Feel woozy? Do this first
People who’ve never experienced wooziness should call 911 if the symptom comes on suddenly or severely, especially if it’s accompanied by other symptoms. However, a person who has experienced wooziness before or been unwell recently should sit down, have a drink of water or juice, and rest for 10 to 15 minutes. If the feeling of wooziness persists, if other symptoms develop, or if it’s hard to get up without feeling faint, one should call 911.
Can long COVID affect the gut?
Some people who have been infected with the virus that causes COVID-19 have experienced lingering effects like low energy and brain fog. Could gastrointestinal problems be another aftereffect of the virus?
Why you keep waking up to go to the bathroom
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.
What's that speck in my eye?
Floaters are shadows that develop in people's field of vision and become more noticeable in certain light. Aging, cataract surgery, and being nearsighted make floaters more likely.
Why won't my hives go away?
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.
Shingles linked with higher risk for heart disease and stroke
People who have had shingles have a 30% increased risk for heart disease and stroke, says a new Harvard study. Learn more about the risk.
A mask that's hard to shed
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.
Vaccination may protect against long COVID
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 skinny on fatty liver
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.
Harvard study: Shingles linked to a spike in risks for heart attack and stroke
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.
