Understanding new weight-loss drugs

A newer class of medications used to treat type 2 diabetes called glucagon-like peptide-1 (GLP-1) receptor agonists has gained attention because of their impressive weight-loss results—in many cases, 10% to 20% of a person's body weight. Versions of two of these GLP-1 receptor agonists, liraglutide (Saxenda) and semaglutide (Wegovy), are FDA-approved for weight loss, even for people without diabetes. However, there isn't enough evidence to know whether these drugs might be beneficial or dangerous for people who are not diagnosed with diabetes or obesity.

Check out your skin

People should do a full-body skin check-up every three to six months to identify abnormalities that may be early signs of skin cancer or other skin problems. Write down the date of the self-exams, record any issues like new or questionable moles, sores, painful or itchy spots, raised or firm bumps, dark flaky patches, and unusual freckles. Include the exact locations of these skin issues and take photos for reference. After six to eight weeks, see a dermatologist if they have not improved, have changed color or size, have become painful, or easily bleed.

Why do medical guidelines change frequently?

Medical recommendations and guidelines, such as colon cancer screening, seem to change often. These contradictions in large part reflect different expert opinions based on the changing scientific information. Rely on your doctor to help determine how these changes may apply to you.

Cannabis use disorder may raise surgical risks

A 2023 study suggests that regular cannabis users have higher risks before, during, and after surgery, including the risk of heart attack, stroke, acute kidney injury, breathing difficulties, and blood clots.

Staying regular

"Regular" bowel movements can mean something different for each person. Some people have a bowel movement once or twice daily; for others, it's once or twice weekly. People should see a doctor if they notice a dramatic change in bowel habits or other symptoms, including fatigue, pain, unintended weight loss, bloody stool, or a change in stool consistency. People can promote digestion by maintaining a toileting schedule, heeding their body's signals, and using a toilet stool.

Debunking common wellness myths

Many common wellness myths contain a grain of truth but are misleading over all. One wellness myth holds that being thin equates to being healthy, but people who are think can still be unhealthy. Another myth posits that detoxes and cleanses can help people be healthier, but these products don't help and can even be dangerous for some people. Another myth is that eating before bedtime leads to weight gain, but food choice matters more than timing.

UK study confirms Mediterranean lifestyle benefits

A 2023 study of about 110,000 people in the United Kingdom suggested that those who most adhered to a Mediterranean lifestyle had a 28% lower risk of dying from cancer and a 29% lower risk of dying prematurely from any cause, compared with those who least adhered to the lifestyle.

Does poor sleep diminish the cognitive benefits of exercise?

In a 2023 study, among people age 50 or 60 who reported high rates of exercise, those who said they slept less than six hours per night had faster rates of cognitive decline over the next 10 years than those who said they got six to eight hours of sleep per night.

10 ways to find purpose in life

Having a sense of purpose is linked to important health benefits, such as longevity and sharp thinking skills. There are many ways to cultivate a sense of purpose. Ideas include thinking about one's strengths or skills and how to apply them; becoming a mentor; volunteering time to a worthy cause; reading Viktor Frankl's book Man's Search for Meaning; writing about lived experiences and sharing the information with family or friends; and thinking of longtime dreams and ways to achieve elements of them.

Injuries and blood thinners: How to stop bleeding

Taking a blood thinner helps protect people at risk for dangerous blood clots that can lead to life-threatening conditions, such as a stroke or heart attack. But the medications increase the risk for uncontrolled bleeding. People taking the drugs should learn what to do in case bleeding occurs. For minor injuries, it's important to apply extra pressure until bleeding stops. For serious injuries, one should call 911 and apply as much pressure as possible to the wound until help arrives. People who take blood thinners and experience even minor injury from a fall or accident should automatically go to urgent care or the emergency department to get checked out, even if there is no apparent bleeding or trauma is observed.
