A 2023 study found that an oral penicillin challenge in a doctor's office provides a simple method of determining true penicillin allergy.

A strong core serves as the foundation for upper- and lower-body movements. It helps maintain a healthy posture and prevents back injuries and falls. Like all muscles, the core muscles weaken as people age, so it's important for people to do core exercises on a regular basis. The best core exercises are movements that activate as many of the core muscles as possible at one time. Some examples include planks, diagonal chops, and deadbugs.

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.

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.

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.

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.

"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.

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.

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.

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.
