A visit with a surgeon can be overwhelming. You may feel anxious about your planned surgery. Many questions could be swirling in your head during a rushed visit. While surgeons have a reputation as technical specialists, bedside manner may be lacking at times.

It sounds simple, but setting the right expectations — on both sides — can ease your anxiety and help you feel more comfortable during a visit with your surgeon. So what exactly does this mean? And how can you accomplish it?

Tell your story

Tell your story to help set clear goals. Beyond simply stating what hurts or what is not working, be sure to include details such as

• how your current condition limits what you enjoy doing
• your daily activities
• how your condition affects your relationship with your social circle and family
• upcoming plans or goals such as travel, or life events like vacations or weddings.

Sharing details like these helps you collaborate to define a successful outcome for surgery.

Listen with your goals in mind

When explaining surgical options, surgeons are obligated to discuss key information, including risks, potential complications, and likely outcomes. Encourage your surgeon to put these facts into context based on what is important to you.

• Ask questions about how surgery will affect things you enjoy doing, such as playing pickleball, taking walks, cooking, reading, or listening to music.
• Ask what you should realistically expect during recovery and once you have recovered. For example, if you have a vacation or travel planned, be sure to discuss how surgery will affect your plans.

Define success before your surgery

Once you are confident that you have told your story and feel like you and your surgeon have set appropriate expectations, take the next step. Ask whether this discussion affects your surgeon’s approach to surgery, and explore how you each define surgical success.

Often, both surgeon and patient agree on a definition of success: for example, remove the entire tumor. But this simple definition may leave room for misalignment. Let’s say a surgeon is able to entirely remove a thyroid tumor, but now the patient speaks in a hoarse voice. While technically successful, this surgery may feel like a failure unless the person understood and accepted the risk that it could affect how they speak.

This highlights the importance of setting expectations. In this example, clear speech after surgery might be your expectation as a patient. Your surgeon must balance explaining how surgical risks might affect that expectation with the reality of treating the condition. Surgery is more likely to feel successful if both sides discuss and align their expectations.

Give yourself time when possible

Processing information about surgery can take time. A surgeon may have to provide realistic expectations that do not align with your initial expectations and hopes.

Some surgeries are urgent, others are not. If you do not need to make an immediate decision, be open with your surgeon. Let them know that you need time to consider the surgeon’s definition of success and your own. Reflecting on the discussion can reduce the stress and anxiety you’re likely to feel during an initial visit.

The bottom line: Making the most of your appointment

Communication goes two ways during a good pre-surgery visit. Do your best to tell your story and emphasize details of your life that are important. When listening, ensure that your surgeon acknowledges these details and describes how surgery may affect your life, as opposed to simply stating technical facts about the surgery. Setting expectations together will help you achieve a common goal and establish a strong surgeon-patient relationship that is essential for a positive surgical outcome.

Lifestyle changes like regular exercise, a healthy diet, and sufficient sleep are cornerstones of self-care for people with type 2 diabetes.

But what about mind-body practices? Can they also help people manage or even treat type 2 diabetes? An analysis of multiple studies, published in the Journal of Integrative and Complementary Medicine, suggests they might.

Which mindfulness practices did the study look at?

Researchers analyzed 28 studies that explored the effect of mind-body practices on people with type 2 diabetes. Those participating in the studies did not need insulin to control their diabetes, or have certain health conditions such as heart or kidney disease. The mind-body activities used in the research were:

• yoga
• qigong, a slow-moving martial art similar to tai chi
• mindfulness-based stress reduction, a training program designed to help people manage stress and anxiety
• meditation
• guided imagery, visualizing positive images to relax the mind.

How often and over what time period people engaged in the activities varied, ranging from daily to several times a week, and from four weeks to six months.

What did the study find about people with diabetes who practiced mindfulness?

Those who participated in any of the mind-body activities for any length of time lowered their levels of hemoglobin A1C, a key marker for diabetes. On average, A1C levels dropped by 0.84%. This is similar to the effect of taking metformin (Glucophage), a first-line medication for treating type 2 diabetes, according to the researchers.

A1C levels are determined by a blood test that shows a person’s average blood sugar levels over the past two to three months. Levels below 5.7% are deemed normal, levels from 5.7% to less than 6.5% are considered prediabetes, and levels 6.5% and higher are in the diabetes range.

How can mind-body practices help control blood sugar?

Their ability to reduce stress may play a big part. “Yoga and other mindfulness practices elicit a relaxation response — the opposite of the stress response,” says Dr. Shalu Ramchandani, a health coach and internist at the Harvard-affiliated Benson-Henry Institute for Mind Body Medicine at Massachusetts General Hospital. “A relaxation response can lower levels of the stress hormone cortisol. This improves insulin resistance and keeps blood sugar levels in check, thus lowering A1C levels.”

A relaxation response can help people with diabetes in other ways, such as by improving blood flow and lowering blood pressure, which protects against heart attacks and strokes.

What else should you know about this study?

The results of studies like this suggest a link between various mind-body practices and lower A1C levels, but do not offer firm proof of it. Levels of participation varied widely. But because all mindfulness practices studied had a modest positive effect, the researchers suggested that these types of activities could become part of diabetes therapy along with standard lifestyle treatments.

Could mind-body practices protect people against developing type 2 diabetes, especially for those at high risk? While this study wasn’t designed to look at this, Dr. Ramchandani again points to the long-range benefits of the relaxation response.

“Reducing and managing stress leads to improved moods, and greater self-awareness and self-regulation,” she says. “This can lead to more mindful eating, such as fighting cravings for unhealthy foods, adhering to a good diet, and committing to regular exercise, all of which can help reduce one’s risk for type 2 diabetes.”

Trying mind-body practices

There are many ways to adopt mind-body practices that can create relaxation responses. Here are some suggestions from Dr. Ramchandani:

• Do a daily 10-minute or longer meditation using an app like Insight Timer, Calm, or Headspace.
• Attend a gentle yoga, qigong, or tai chi class at a local yoga studio or community center.
• Try videos and exercises to help reduce stress and initiate relaxation responses.
• Practice slow controlled breathing. Lie on your back with one or both of your hands on your abdomen. Inhale slowly and deeply, drawing air into the lowest part of your lungs so your hand rises. Your belly should expand and rise as you inhale, then contract and lower as you exhale. Repeat for several minutes.

Want your child to grow up healthy, happy, smart, capable, and resilient? Play with them. Infants and toddlers thrive on playful games that change as they grow.

Why does play matter during the first few years of life?

More than a million new nerve connections are made in the brain in the first few years of life. And pruning of these neural connections makes them more efficient. These processes literally build the brain and help guide how it functions for the rest of that child’s life. While biology — particularly genetics — affects this, so does a child’s environment and experiences.

Babies and children thrive with responsive caregiving. Serve and return, a term used by the Harvard Center on the Developing Child, describes this well: back-and-forth interactions, in which the child and caregiver react to and interact with each other in a loving, nurturing way, are the building blocks of a healthy brain and a happy child, who will have a better chance of growing into a healthy, happy, competent, and successful adult.

Play is one of the best ways to do responsive caregiving. To maximize the benefits of play:

• Bring your full attention. Put the phone down, don’t multitask.
• Be reciprocal. That’s the “serve and return” part. Even little babies can interact with their caregivers, and that’s what you want to encourage. It doesn’t have to be reciprocal in an equal way — you might be talking in sentences while your baby is just smiling or cooing — but the idea is to build responsiveness into the play.
• Be attuned to developmental stages. That way your child can fully engage — and you can encourage their development as well.

Great games to play with infants: 6 to 9 months

The Center for the Developing Child has some great ideas and handouts for parents about specific games to play with their children at different ages.

6-month-olds and 9-month-olds are learning imitation and other building blocks of language. They are also starting to learn movement and explore the world around them.

Here are some play ideas for this age group:

• Play peek-a-boo or patty-cake.
• Play games of hiding toys under a blanket or another toy, and then “find” them, or let the baby find them.
• Have back-and-forth conversations. The baby’s contribution might just be a “ma” or “ba” sound. You can make the same sound back, or pretend that your baby is saying something (“You don’t say! Really? Tell me more!”).
• Play imitation games: if your baby sticks out their tongue, you do it too, for example. Older babies will start to be able to imitate things like clapping or banging, and love when grownups do that with them.
• Sing songs that involve movement, like “Itsy Bitsy Spider” or “Trot, Trot to Boston” with words and motions.
• Play simple games with objects, like putting toys into a bucket and taking them out, or dropping them and saying “boom!”

Great games to play with toddlers

Between 12 months and 18 months, young toddlers are gaining more language and movement skills, and love to imitate. You can:

• Play with blocks, building simple things and knocking them down together.
• Do imaginative play with dolls or stuffed animals, or pretend phone calls.
• Use pillows and blankets to build little forts and places to climb and play.
• Play some rudimentary hide-and-seek, like hiding yourself under a blanket next to the baby.
• Continue singing songs that involve movement and interaction, like “If You’re Happy And You Know It.”
• Go on outings and explore the world together. Even just going to the grocery store can be an adventure for a baby. Narrate everything. Don’t worry about using words your baby doesn’t understand; eventually they will, and hearing lots of different words is good for them.

Older toddlers, who are 2 or 3 years old, are able to do more complicated versions of these games. They can do matching, sorting, and counting games, as well as imitation and movement games like “follow the leader” (you can get quite creative and silly with that one).

As much as you can, give yourself over to play and have fun. Work and chores can wait, or you can actually involve young children in chores, making that more fun for both of you. Checking social media can definitely wait.

Playing with your child is an investment in your child’s future — and a great way to build your relationship and make both of you happy.

The current shortage of semaglutide (Ozempic), an important diabetes drug, has an unusual origin: too many people without diabetes are taking it. Here’s how that happened, and how we might course-correct to help ensure that those with the greatest need for this medicine can get it.

A diabetes drug with an important side effect: Weight loss

Semaglutide (Ozempic) was first approved by the FDA in 2017 to help people with type 2 diabetes keep blood sugar under control. But during pre-approval studies, researchers noticed a remarkable side effect: people lost weight. For example, in one pivotal study, average losses for those receiving one milligram a week of semaglutide were:

• nearly 10 pounds lost over 30 weeks
• nearly 5% overall body weight lost
• waist size shrank 1.6 inches.

This side effect helped people with type 2 diabetes because excess weight is a major risk factor for the condition. Among other health benefits, weight loss can lower blood sugar and blood pressure, and reduce the need for other diabetes medications.

Turning a side effect into a selling point

Unintended weight loss would usually be listed as a side effect for a study medication. But ads for Ozempic didn’t list it with the other possible side effects; instead, it was featured as a benefit. The Ozempic “Tri-Zone” (a phrase concocted by marketers, not medical experts) promised improved blood sugar control, lower cardiovascular risk, and weight loss.

At the bottom of the ad, fine print that’s easy to miss states: “Ozempic is not a weight loss drug.” Talk about mixed messages!

The makers of Ozempic saw the potential of semaglutide as a weight loss drug for people without diabetes. Sure enough, clinical trials confirmed that overweight and obese people taking semaglutide also lost substantial weight. Semaglutide received FDA approval in 2021 for people with obesity (BMI of 30 or greater), or who were overweight (with a BMI of 27 to 29.9) and had a medical problem related to excess weight, such as high blood pressure or high cholesterol. As a weight loss drug, it was rebranded as Wegovy.

The only difference between the two drugs? The maximum approved dose of semaglutide is a bit higher with Wegovy than Ozempic.

How social media fueled the Ozempic shortage

Soon after the approval of Wegovy, celebrities and social media influencers began taking it and sharing glowing weight loss experiences. What’s more, medicines approved for specific uses in the US can be prescribed off-label for any use: up to 38% of all prescriptions written in the US are off-label (note: automatic PDF download). So, it’s likely some of the viral run on Wegovy was fueled by people who wanted to lose weight but had no medical reason to take it.

After high demand put Wegovy in short supply, many turned to Ozempic to lose weight. And that contributed to a shortage of Ozempic, threatening the health of people with type 2 diabetes who rely on the drug.

Readjust priorities and limit irresponsible prescribing

This situation couldn’t have happened without physicians or other health care professionals willing to write Ozempic prescriptions for people who did not have diabetes or another medical reason to use semaglutide. And that suggests an obvious solution: limit prescriptions for Ozempic to people with diabetes. For many drugs, a prior authorization process requires certain conditions be met before a prescription can be filled. This could be done for Ozempic.

And of course, we should encourage people who don’t have diabetes not to request a prescription for Ozempic. While that message is unlikely to show up in a drug ad, public service announcements could do the trick.

The bottom line

Drug ads often urge you to ask your doctor if a treatment is right for you. But we already know a key piece of the answer for Ozempic: if you don’t have diabetes, don’t ask for a diabetes medicine to help with weight loss. There are better ways to get the help you need to reach a healthy weight if you are overweight or obese. Talk to your doctor about a full range of treatment options. And if your weight is already in a healthy range, it’s not a good idea to take a medication to become thinner.

Finally, to keep vitally important medicines available for those who need them most, health care professionals must prescribe them responsibly. Responsible requests by their patients could help.

Pregnancy is often painted as a time of elation and joy, emotions many people may indeed feel. As doctors, though, it’s hard to ignore the health risks and the fears that can arise in the wake of a positive pregnancy test for some of our most vulnerable patients.

Simply being pregnant poses significant short-term and long-term risks to health, particularly in the US. We have the highest rate of serious pregnancy-related complications among developed nations, resulting in about 700 deaths a year nationally. This health burden is unequally distributed, falling hardest on women of color and low-income women — in fact, Black women are three times as likely to die as white women from pregnancy-related complications.

What makes pregnancy challenging from a health standpoint?

Pregnancy acts as an ongoing stress test that taxes body systems and generates unique health risks. It changes how the heart, lungs, and kidneys function. It also alters the immune system, and changes metabolism through effects on various organs. It increases blood flow throughout the body. The impact is greater for anyone who already has high blood pressure, diabetes, or other health conditions. Additionally, pregnancy can also deepen existing mental health disorders such as depression and anxiety, often exacerbating symptoms.

Two health issues unique to pregnancy are:

• Preeclampsia. This causes high blood pressure and possible damage to other organs, such as the kidneys, liver, and brain. Pregnancy alone places extra stress on the heart and blood vessels. Having a pregnancy affected by preeclampsia more than triples one’s lifetime risk of cardiovascular disease such as stroke or heart attack, according to the Preeclampsia Foundation. The biggest risk factors for developing preeclampsia are being younger than 18 or older than 40, autoimmune disease (such as lupus), existing high blood pressure, or preeclampsia in a prior pregnancy.
• Excess bleeding after birth (postpartum hemorrhage). While certain factors put people at higher risk, hemorrhage may occur with any birth, even those that follow uncomplicated pregnancies.

Most often, pregnancy can be safely navigated even when a person has health conditions. Yet having an existing condition like heart disease or diabetes does raise risk for complications and death. Now that pregnancies at later ages are more common, existing heart disease is complicating more pregnancies. Once rarely needed, large multidisciplinary teams of health professionals are now often required to care for pregnant people with complex cardiac needs or other health conditions.

Many pregnancies are unintended

Nearly half of all pregnancies in the United States are unintended. In some cases that means a pregnancy is wanted at a future time; in others that a pregnancy is not desired.

Why do so many unintended pregnancies occur? Nine in 10 sexually active women who are not trying to get pregnant report using some form of birth control. Of course, not all types of birth control are highly effective. In a year of use, 13 out of 100 people relying on condoms alone — and up to 23 out of 100 relying on fertility awareness methods — will become pregnant.

Unintended pregnancies occur even when people use very effective contraceptives. With perfect use (which is very hard to achieve), fewer than one in 100 women taking birth control pills for a year will become pregnant. With typical use, seven in 100 will become pregnant. More than 13 million US women use surgical sterilization, such as tubal ligation, as a permanent form of birth control. Given the failure rate of nearly one in 100, research suggests more than more than 65,000 unintended pregnancies may occur annually after these procedures.

Health factors in, too. Certain medical conditions or medications, such as medicines used to treat epilepsy, may also increase the risk of contraceptive failure. Health conditions also dictate whether people can use some of the more effective forms of birth control.

A narrowing of health care choices and life choices

Pregnancy, childbirth, and parenting alter the trajectory of many lives — parents, siblings, and wider family — even when people choose this path. Since June 2022, when the Dobbs Supreme Court decision overturned a national constitutional right to abortion, at least 14 states have banned or severely restricted the ability to make choices once pregnant. Even before Dobbs, nearly 10% of people seeking abortion care in the US had to travel out of state.

Research shows that women who seek an abortion but are denied abortion care are more likely to have health problems during their pregnancy and to experience financial difficulties or live in poverty years later. State bans on abortion care will have a disproportionate impact on Black and low-income women, who already are at higher risk for complications or death related to childbirth. Ultimately, legislation that restricts or bans comprehensive health care that includes abortion care puts all people capable of pregnancy at risk — medically, economically, and socially.

Like pregnancy itself, the decision to remain pregnant is deeply personal. And as with all health care, patients and physicians should be able to freely consider all medical options to help guide decisions, including ending a pregnancy. Although abortion care is more restricted today than it has been since 1973, options are available and remain a critical part of maternal health care.

Are you having a little trouble hearing conversations? If so, you’re not alone. An estimated 23% of Americans ages 12 and older have hearing loss. Although most of those people have mild hearing loss, for people ages 80 years and older, it’s more common for hearing loss to be moderate to severe than mild.

But not only is moderate to severe hearing loss disruptive to one’s life, it also makes you more likely to develop dementia. A new study helps explain why — and what you can do about it.

What did the new study look at and find?

A study published in JAMA focused on a sample of adults in the United States from the National Health and Aging Trends Study, which follows Medicare beneficiaries. The participants sampled were 70 or older.

The researchers found that about 33% of participants had normal hearing, 37% had mild hearing loss, and 30% had moderate to severe hearing loss. Dementia occurred least often among those with normal hearing (6%), more often among those with mild hearing loss (9%), and most often among those with moderate to severe hearing loss (17%). That’s a large increase in risk, particularly for those whose hearing loss is moderate to severe.

What else to know about this study

The study sample was selected to make it possible to analyze subgroups by age and apply findings to a diverse population. The sample included additional participants ages 90 years and older, and additional participants who identified as Black. Of the 2,413 total participants, 53% were ages 80 years and older, 56% were female, 19% were non-Hispanic Black, 4.5% were Hispanic, and 74% were non-Hispanic white.

Also, unlike previous research, this study looked objectively at hearing loss and dementia. Prior research had shown that hearing loss is thought to account for about 8% of all dementia cases worldwide. Exactly why the connection exists is not known.

It’s important to note that most large studies that found this link were based on questionnaires that people fill out. In other words, no one actually measured the hearing of those participating in the study to make sure that they had hearing loss — or that their hearing was really normal.

In this new study, however, the investigative team used an electronic tablet-based audiometer to evaluate participants’ hearing for four pure tone frequencies that are most important for understanding speech. So, for the first time in a large study, there was objective measurement of hearing loss.

How do hearing aids reduce the risk of dementia?

If you have hearing loss, does that mean you’re doomed to develop dementia? Not at all. This study found that those with moderate to severe hearing loss could significantly reduce their risk of dementia simply by using hearing aids.

This research helps us understand why hearing loss causes dementia. Here’s the connection:

There is increasing evidence that the more the brain is stimulated, the less likely it is that dementia will develop. When there is hearing loss, auditory stimulation is reduced. This, by itself, likely increases dementia risk. But even more important is that when an individual suffers from moderate to severe hearing loss, they are less likely to participate in social activities. Perhaps they are embarrassed about their hearing loss. Or they may simply find it unrewarding to attend a social event when they cannot hear what is going on.

It turns out that social activities are one of the best ways to stimulate the brain, as there is evidence that our brains evolved to facilitate social behavior. Given all this information, you won’t be surprised to learn that reduced social activity has been linked to cognitive decline. Thus, this new study provides additional evidence that the reason hearing loss increases the risk of dementia is because hearing loss reduces brain stimulation — both directly and through reduced social interaction.

What to do if you have hearing loss

Don’t let hearing loss raise your risk of dementia.

• Keep your ears clean. (But remember, never put anything in your ears smaller than your elbow. Ask your doctor if you’re not sure how to clean your ears.)
• If you can’t hear and you don’t have hearing aids, get them. Hearing aids now available over the counter can help many people with mild to moderate hearing loss.
• If you have hearing aids, wear them.
• If your hearing aids aren’t working, get them fixed.
• Don’t be passive — ramp up your social life and other activities.

All these things will help to reduce your risk of dementia. And you might just find that, despite some hearing loss, you’re enjoying life more.

It used to be that doctors would automatically recommend treating all men with prostate cancer, even if their initial biopsies suggested the disease would grow slowly (or at all). But during the last several decades, the pendulum on treatment has swung the other way.

Doctors are now likely to advise active surveillance for low- to intermediate-risk cancers that may never turn deadly over the course of a man’s life. Active surveillance involves routine PSA checks, follow-up biopsies, and more recently, magnetic resonance imaging of a patient’s tumor. Treatment is initiated only when — or if — the disease shows signs of progression.

Recent evidence from Johns Hopkins University shows that the long-term risks of metastasis and death from low-grade prostate cancer among men on active surveillance averages just 0.1%. But doctors who care for such men also face a nagging question: which of their patients might have more aggressive cancer that should require closer monitoring? New findings published by the Johns Hopkins team in January provide useful insights.

The researchers’ approach

The researchers in this case zeroed in on the prognostic value of so-called perineural invasion, or PNI, on tumor biopsy samples. PNI simply means that cancer cells are moving into the perineural space between nerves in the prostate and their surrounding tissues. A finding of PNI raises red flags because the perineural space “provides a conduit by which tumor cells can potentially escape the prostate and grow elsewhere in the body,” says Dr. Christian Pavlovich, a urologic oncologist at Johns Hopkins who led the research.

Dr. Pavlovich’s team wanted to know if PNI detected on initial or follow-up biopsies would be associated with higher risks for cancer progression. So they analyzed long-term follow-up data from 1,969 men who had enrolled in an active surveillance research protocol at Johns Hopkins between 1995 and 2021. All the men were diagnosed initially with Grade Group 1 prostate cancer (the least risky form of the disease) and had undergone at least one follow-up biopsy since then.

What did the results show?

Among the 198 men with PNI, 44% of them (87 men in all) eventually progressed to Grade Group 2 prostate cancer, which is a more advanced form of the disease with an intermediate risk of further spread. Conversely, just 26% of the remaining 1,771 men without PNI (461 men) had progressed to Grade Group 2.

Pavlovich emphasizes that despite the new findings, PNI “does not make patients ineligible for active surveillance.” Importantly, the research showed that PNI was not associated with high-risk features, such as cancer in the lymph nodes of patients who wound up having surgery, or post-surgical elevations in PSA that show cancer still lurks in the body.

“What we’ve really shown here is that PNI puts men at a slightly higher risk of extraprostatic extension (cancer cells located just beyond the confines of the prostate),” Pavlovich says. “This is not necessarily a new finding. But PNI only occurs in about 10% of Grade Group 1 patients, and this is the boldest statement yet from the largest study conducted so far.” Pavlovich and his colleagues concluded that PNI provides an inexpensive and readily available indicator for identifying which men on active surveillance will benefit from more intensive monitoring protocols, including MRI and genetic tests.

Dr. Marc B. Garnick, the Gorman Brothers Professor of Medicine at Harvard Medical School and Beth Israel Deaconess Medical Center, agrees, while pointing out that PNI evaluations aren’t performed often enough. A PNI analysis of pathology specimens, he says, “along with emerging and sophisticated genetic testing of the tissue samples, may lead to more certainty in our recommendations to patients.”

How well are you protecting yourself against heart disease, the nation’s leading cause of death? A check of five important numbers can give you a good idea: blood pressure, blood sugar, LDL cholesterol and triglyceride levels, and waist circumference. Those values provide a picture of a person’s overall health and, more specifically, what factors they may need to address to lower their chance of a heart attack or stroke.

Below are the ideal values for each measurement, along with why they’re important and targeted advice for improving them. Universal suggestions for improving all five measurements appear at the very end.

How do your heart health numbers stack up?

While the ideal values are good goals for most people, your doctor may recommend different targets based on your age or other health conditions.

Blood pressure

Less than 120/80 mm Hg

Blood pressure readings tell you the force of blood pushing against your arteries when your heart contracts (systolic blood pressure, the first number) and relaxes (diastolic blood pressure, the second number). Your blood pressure reflects how hard your heart is working (when you’re resting or exercising, for example) and the condition of your blood vessels. Narrowed, inflexible arteries cause blood pressure to rise.

Why it matters to heart health: High blood pressure accelerates damage to blood vessels, encouraging a buildup of fatty plaque (atherosclerosis). This sets the stage for a heart attack. High blood pressure forces the heart’s main pumping chamber to enlarge, which can lead to heart failure. Finally, high blood pressure raises the risk of strokes due to a blocked or burst blood vessel in the brain.

What helps: A diet rich in potassium (found in many vegetables, fruits, and beans) and low in sodium (found in excess in many processed and restaurant foods); minimizing alcohol.

LDL cholesterol

Less than 70 mg/dL

A cholesterol test (or lipid profile) shows many numbers. Doctors are usually most concerned about low-density lipoprotein (LDL) cholesterol, particles that makes up about two-thirds of the cholesterol in the blood.

Why it matters to heart health: Excess LDL particles lodge inside artery walls. Once there, they are engulfed by white blood cells, forming fat-laden foam cells that make up atherosclerosis.

What helps: Limiting saturated fat (found in meat, dairy, and eggs) and replacing those lost calories with unsaturated fat (found in nuts, seeds, and vegetable oils).

Triglycerides

Less than 150 mg/dL

Perhaps less well-known than cholesterol, triglycerides are the most common form of fat in the bloodstream. Derived from food, these molecules provide energy for your body. But excess calories, alcohol, and sugar the body can’t use are turned into triglycerides and stored in fat cells.

Why it matters to heart health: Like high LDL cholesterol, elevated triglyceride values have been linked to a higher risk of heart attack and stroke.

What helps: Limiting foods that are high in unhealthy fats, sugar, or both; eating foods rich in omega-3 fatty acids (such as fish); avoiding alcohol.

Blood sugar

Less than 100 mg/dL (fasting)

High blood sugar defines the diagnosis of diabetes. Type 2 diabetes is most common. It occurs when the body develops insulin resistance (insulin enables cells to take in sugar) and does not produce enough insulin to overcome the resistance.

Why it matters to heart health: High blood sugar levels damage blood vessel walls and cause sugar (glucose) to attach to LDL. This makes LDL more likely to oxidize — another factor that promotes atherosclerosis. Excess sugar in the blood also makes cell fragments called platelets stickier so they’re more likely to form clots, which can trigger a heart attack or stroke.

What helps: Avoiding sugary beverages and foods high in sugar; eating whole, unprocessed grains instead of foods made with refined grains (white flour, white rice).

Waist circumference

Whichever number is lower:

Less than half your height in inches

OR

Women: Less than 35 inches

Men: Less than 40 inches

Measure your waist around your bare abdomen just above your navel (belly button). A big belly — what doctors call abdominal or visceral obesity — usually means fat surrounding internal organs.

Why it matters to heart health: Visceral fat secretes hormones and other factors that encourage inflammation, which triggers the release of white blood cells involved in atherosclerosis.

What helps: Consuming fewer calories, especially those from highly processed foods full of sugar, salt, and unhealthy types of fat.

Universal advice to improve all five measures of heart health

If one or more of your numbers is above ideal levels, you’re far from alone. Most Americans are overweight or obese and have bigger-than-healthy bellies. Excess weight and waist circumference affect blood pressure, LDL cholesterol, triglycerides, and blood sugar. Eating a healthy, plant-based diet can help. Regular exercise also helps: aim for at least 30 minutes of moderate-intensity exercise like brisk walking most days. Other lifestyle habits that can lower your heart disease risk include getting seven to eight hours of sleep nightly and managing your stress level.

Psychedelic drugs have been capturing the attention of doctors and patients alike, for their increasingly proven potential to effect long-lasting improvements in the mental health of people who are suffering from conditions such as treatment-resistant depression. Microdosing of psychedelic substances such as LSD or psilocybin involves taking a fraction of a regular dose (a subperceptual dose) that is much lower than one would take if one wanted to “trip” or hallucinate on these substances.

Many people share the idea that microdosing with psychedelics enhances one’s mood, creativity, concentration, productivity, and ability to empathize with others. Or could the benefits be an “expectancy effect”? This means that most people who take a daily pill that they fervently expect will help them feel happier and smarter will feel like they are happier and smarter — just from taking the pill, regardless of what’s in it.

What is microdosing?

There isn’t a single, clearly recognized definition of microdosing for any psychedelic drug, and this complicates attempts to perform consistent research. One definition is approximately 1/5 to 1/20 of a recreational dose. (From anecdotal experience this is accurate, as a medium-strength dose of psilocybin is 2 to 3 grams of dried mushrooms, and a microdose is typically around 0.3 grams.) One obstacle is that the potency of mushrooms can vary greatly, as they are not regulated outside of clinical trials, so this isn’t an exact science. Likewise, LSD is an invisible, tasteless, odorless substance that usually comes either in liquid form or embedded into a piece of paper to be slipped under the tongue.

Given its current illegality and lack of regulation, there is no good way to know what dosage you are taking unless you have an extraordinarily reliable supplier. LSD is an extremely powerful and long-acting drug, and you don’t want to take more of it than intended. Further, psychedelics such as psilocybin and LSD can produce physiological tolerance, which might suggest that, even if microdosing does help, there could be diminishing returns if one stays at the same dosage.

Is microdosing safe?

We don’t know as much about safety as we might have learned if not for the War on Drugs, which curtailed much of the research into psychedelics starting in the late 1960s. This research has been renewed over the last five to 10 years, and many medical centers are conducting research on psychedelics. Psilocybin is generally thought to be safe in low dosages and has been used for centuries by indigenous peoples. However, if one takes too large a dose it can result in a terrifying — even traumatic — experience.

Psilocybin is a compound produced by almost 200 species of fungi (mushrooms), and the mushrooms must come from a trusted source. It is very easy to poison oneself with the wrong type of mushroom, as there are many types of mushrooms in nature that can look quite similar to each other, but some are poisonous and can harm your liver, causing severe illness or even death.

Could psychedelics become safer if legalized?

It is anticipated by experts in the field that some psychedelics may become fully legalized — for medical usage, under supervision — within the next few years, specifically psilocybin and MDMA (ecstasy). Some policy makers and public health experts believe that the safety of these psychedelics would be enhanced if they were decriminalized, and if their cultivation and production were monitored and regulated. At least one state (Oregon), and many cities around the country, have decriminalized psychedelics at the local level.

Some advocates of decriminalization are looking forward to a safer product, and wider access that could include not having to see a medical professional to get a prescription or be under medical supervision when using psychedelics. Skeptics are worried that uncontrolled access to these drugs might affect patients with mental illness, or might even precipitate mental illness such as psychosis in people that are vulnerable.

It is important to mention that the use of all psychedelic drugs should be undertaken with utmost caution — if they should be used at all — in patients with major mental illness such as schizophrenia or bipolar disorder. For safety reasons, these patients are typically excluded from studies involving psychedelic drugs.

Evidence for microdosing of psychedelics is mixed

Does microdosing work? In short, the jury is still out. Some studies indicate a very real and significant benefit from microdosing, whereas others are much less convincing and show little to no benefit. One recent study used a naturalistic, observational design to study 953 psilocybin microdosers compared with 180 nondosing participants for 30 days, and found “small to medium-sized improvements in mood and mental health that were generally consistent across gender, age, and presence of mental health concerns.” This study and others like it appear to confirm many anecdotal reports of people who swear by the benefits they have experienced from microdosing.

Other studies on microdosing are far less impressive. In one example the researchers conducted a randomized controlled study, which represents the strongest type of evidence because it weeds out the placebo effect. The researchers took 34 patients and randomized half of them to receive psilocybin and half to placebo. While there were some intriguing subjective effects (people felt happier and more creative), and even some changes in brain waves recorded on an EEG machine, they concluded that low-dose psilocybin mushrooms did not show objective evidence of improvements in creativity, well-being, and cognitive function. Studies such as this one support the hypothesis that the effect people receive from psychedelics at these subperceptual doses is mostly an expectancy effect, and that one needs to consume a higher dosage to receive a therapeutic benefit.

To microdose or not to microdose?

While any medical or lifestyle decision is an individual’s choice (assuming that they aren’t harming others), I would highly recommend that you speak with your doctor to explore your decision to take psychedelics, and see if there are any medical reasons why you should be cautious or avoid these drugs. It is critical to pay attention to the legality and the quality of your product — you likely can’t afford to get into legal jeopardy, and certainly can’t afford to poison yourself.

Finally, it is important to understand that there isn’t yet definitive proof that microdosing is at all helpful, or even that it is safe in the long term. With these points in mind, it is fair to say that psychedelic drugs are becoming better understood, and are undergoing a resurgence of research and a more widely accepted use.

Ketamine is an unusual type of psychedelic drug — called a dissociative — that is undergoing a resurgence in popularity. Originally derived from PCP, or “angel dust,” ketamine has been used in hospitals and veterinary clinics as an anesthetic for decades, and has been cited as a drug of misuse under the moniker “special K.”

It is the effects that ketamine reliably produces that underlie both its medical and recreational uses: pain control, forgetfulness, intoxication, disassociation, and euphoria. Recently, it has been used more widely due to its approval for treatment-resistant depression (TRD) — that is, severe depression that has not improved via other therapies, including people who are experiencing suicidal thoughts.

Evidence of the benefit of ketamine

A prescription version of ketamine called esketamine (Spravato), given through a nasal spray, was approved in 2019 by the FDA for TRD; however, according to the guidelines, it is only to be used “under the supervision of a health care provider in a certified doctor’s office or clinic.” That means medical professionals need to watch you use it, and then follow you after you’ve taken your dose, checking your vital signs and how you are doing clinically.

The effectiveness of ketamine for TRD was first demonstrated for short-term treatment in research that resulted in clinically and statistically significant decreases in depression scores for ketamine versus placebo (In both groups in this study, the patients continued with their regular antidepressants because of concern of not treating TRD in the placebo arm.) Nasal ketamine was shown to have longer-term efficacy, in a study where ketamine (plus the regular antidepressant) helped people stay in stable remission 16 weeks into treatment.

Relief from TRD with ketamine happens rapidly. Instead of waiting for an SSRI to hopefully provide some relief over the course of weeks, people who are suffering under the crushing weight of depression can start to feel the benefits of ketamine within about 40 minutes.

Is ketamine the right treatment for you?

This is a discussion that should include your primary care doctor, your mental health provider, and any other health care professionals who care for you. It’s important to remember that ketamine isn’t a first-option treatment for depression, and it is generally used only when other, more longstanding treatments haven’t been effective. It is not thought to be curative; rather, it improves symptoms for a certain amount of time. It is easier to say who isn’t appropriate for ketamine treatment, based on the side effects.

Should you go to a ketamine clinic for treatment?

Independent, outpatient ketamine clinics are popping up all over the place. It is estimated that there are currently hundreds to thousands of these clinics — almost all of which were established in 2019 when ketamine was approved for TRD. Typically, these clinics are for-profit enterprises that are staffed by some combination of either a psychiatrist or an anesthesiologist (who can administer the infusion), a nurse, a social worker, and (of course) the businesspeople who make it all work.

In writing this piece, I called several ketamine clinics, posing as a patient, to investigate what would be involved in receiving ketamine therapy. Most of them seemed as if they would provide ketamine for me without any major hurdles, after an introductory medical interview by a nurse or a social worker. A few clinics required communication or a diagnosis from my psychiatrist — and this seemed quite sensible.

The clinics operate on a fee-for-service arrangement, so you would pay out of pocket, as insurance rarely covers this treatment. In the Boston area where I live, the ketamine infusions cost about $600 each, and a course of six infusions and a clinical re-evaluation are typically recommended. (I should note that the ketamine clinics affiliated with medical academic institutions seem to have more safeguards in place, and they may also be enrolling people in clinical trials.)

Are ketamine clinics safe?

These ketamine clinics raise many questions — namely, what does one look for in a reputable and safe ketamine clinic? Currently, we don’t yet have definitive answers to that question. One wonders if a ketamine infusion, which can cause a profound dissociation from reality, would be better controlled in a hospital setting, where there are protocols for safety in case anything goes wrong. It was unclear (in part because I didn’t actually go through with the therapy) how much communication, if any, there would be between the ketamine clinic staff and your health care providers, and typically the treatments you receive would not be included in your primary electronic medical record.

What are the side effects?

Ketamine is generally considered safe, including for those who are experiencing suicidal ideation (thoughts or plans for suicide). The main side effects are dissociation, intoxication, sedation, high blood pressure, dizziness, headache, blurred vision, anxiety, nausea, and vomiting. Ketamine is avoided or used with extreme caution in the following groups:

• people with a history of psychosis or schizophrenia, as there is concern that the dissociation ketamine produces can make psychotic disorders worse
• people with a history of substance use disorder, because ketamine can cause euphoria (likely by triggering the opioid receptors) and some people can become addicted to it (which is called ketamine use disorder)
• teenagers, as there are some concerns about the long-term effects of ketamine on the still-developing adolescent brain
• people who are pregnant or breastfeeding
• older adults who have symptoms of dementia.

More detailed research needs to be done on the longer-term benefits and side effects of ketamine treatment, and on its safety and effectiveness for teens and older adults, as well as for the emerging indications of ketamine therapy for PTSD, OCD, alcohol use disorder, and other mental health conditions.

Finally, there is some concern that, with repeated dosing, ketamine can start to lose its effectiveness and require larger doses to produce the same effect, which is not sustainable.

Ketamine could provide hope for people with serious depression

Serious, treatment-resistant depression can rob people of hope for the future and hope that they will ever feel better. Ketamine can provide help and hope to patients who have not found relief with any other treatments. Given its efficacy in people considering suicide, it is plausible that ketamine may be lifesaving.

As we learn more from research on ketamine and from people’s experiences in newer clinics, we will be better able to answer the questions of ketamine’s longer-term effectiveness and what safeguards are needed for treatment. We may also learn who is most likely to safely benefit from ketamine therapies, and the best method of administration: intravenous infusion, a nasal spray, or a pill.
