Melasma, which causes dark patches on the face, is far more prevalent in women than in men. Dubbed the "mask of pregnancy," melasma triggers include not only pregnancy but also hormonal fluctuations, genetics, and sun exposure. People with darker skin are more prone to it. Melasma is typically treated with topical products that lighten the skin or slough off cells. Laser treatments and chemical peels, however, may worsen melasma. Sunscreen use can help prevent flares.

Hives are red, itchy welts that crop up on the skin. Allergic reactions and stress, among other triggers, can cause episodes of hives, which typically last several days to a couple of weeks. Cases that last six weeks or longer may be autoimmune hives.

Getting at least one dose of a COVID vaccine lowers the risk of developing long COVID even among people who were previously unvaccinated and recovered from COVID.

The body's second largest organ, the liver is responsible for more than 500 bodily functions. One of the liver's greatest threats is nonalcoholic fatty liver disease (NAFLD), an umbrella term that includes several forms of liver disease. Most people with NAFLD have a type known as simple fatty liver. However, up to 20% of people with NAFLD develop inflammation in the liver known as nonalcoholic steatohepatitis (NASH). Left unchecked, this more dangerous form can progress into fibrosis (scarring) and potentially cirrhosis (severe scarring and liver damage). Lifestyle changes, such as weight loss, increasing exercise, and adopting a plant-based diet are the best means to manage and prevent NAFLD.

A 2022 observational study that included more than 200,000 people found that those who'd had shingles at some point had a 30% higher long-term risk for a major cardiovascular event, compared with people who didn't have shingles.

People with knee arthritis who don't feel ready for joint replacement can take a number of steps as they ponder the possibility. These include getting knee injections or wearing a brace to reduce pain, modifying activities (such as exercise) that aggravate knee pain, losing weight to take pressure off the knee joint, exercising more to help with weight control, seeking physical therapy, getting underlying health conditions under control, doing research about knee replacement, and talking to an orthopedic surgeon.

Making one or more trips to the bathroom every night is the defining characteristic of a medical condition called nocturia. It can be caused by aging, lifestyle habits, or underlying conditions such as an overactive bladder or (in men) an enlarged prostate. Treating nocturia starts with lifestyle changes such as avoiding fluids several hours before bedtime, eliminating caffeinated drinks 10 hours before bedtime, and limiting evening alcohol intake. Medications, pelvic floor exercises, injections of botulinum toxin (Botox), or nerve stimulation treatments may also help.
