While the FDA rules for blood donation were revised twice in the last decade, one group — men who have sex with men — continued to be turned away from donating. Now new, evidence-based FDA rules will focus on individual risk rather than groupwide restrictions.

Many chronic conditions seem to be related. Examples include obesity, high blood pressure, type 2 diabetes, high cholesterol, and heart disease; hearing loss and dementia; obstructive sleep apnea and high blood pressure; various autoimmune diseases; and obesity and joint problems. People with chronic conditions should ask their doctors about the risk for associated diseases.In some cases, they should have certain health screenings to check for them. In other cases, additional screening isn't automatic.

Tens of millions of people who've had COVID-19 suffer with persisting symptoms. The condition is called long COVID. Symptoms, such as fatigue, difficulty concentrating, and disrupted sleep, can seriously impair the ability to function at work and at home. Vaccines and antiviral drugs appear to offer some protection against getting long COVID. But more information is needed. The National Institutes of Health has committed over $1 billion to discover how to better diagnose, effectively treat, and ultimately prevent long COVID.

Irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) are different, though they can have similar symptoms. IBS symptoms seem to arise from hypersensitive nerves and abnormal muscle contractions in the digestive tract, while IBD results from a problem with the immune system causing inflammation.

A rapid heart rate—tachycardia—is a key feature of postural orthostatic tachycardia syndrome, or POTS, a mysterious condition that involves the nervous system and can cause a constellation of symptoms, including fatigue, shortness of breath, headaches, and brain fog, as well as pain in the chest, extremities, or elsewhere in the body. At least half of all cases of POTS are thought to be triggered by an infection (such as mononucleosis), which then spurs inflammation or an autoimmune response. Treatment includes drinking lots of water, eating lots of salt, and graded exercise training.

Scientists are testing potential vaccines that aim to prevent urinary tract infections (UTIs). Until then, strategies that may help ward off UTIs include drinking lots of water each day, emptying the bladder after sexual intercourse, using vaginal estrogen creams (for women), wiping front to back after gong to the bathroom (for women), taking a daily long-term, low-dose antibiotic, taking a single dose of an antibiotic after sex (if recurrent UTIs often follow sexual intercourse), or taking cranberry supplements.
