Can health marketing be harmful? Watch out for health ads that make misleading or even dangerous claims that an unproven product or treatment is better than a proven one.
Health advice tells us to eat less processed food, but what does that mean? Researchers compared diets with most of the calories from unprocessed foods and from ultra-processed foods, to see how the subjects were affected.
A sense of dizziness or spinning associated with migraine headache is called vestibular migraine. A small study found that a type of nerve stimulation treatment improved symptoms of vestibular migraine in study participants.
Recently, Annals of Internal Medicine published guidelines for consumption of red meat and processed meats that are at odds with established evidence of the increased risk of early death, cardiovascular disease, and cancer. So, how much red meat should we be eating?
A recent study confirms that people born with congenital heart disease have a significantly greater risk of being diagnosed with an autism spectrum disorder. The research highlights the need for autism screening in children with CHD as early as possible.
There are many things about hospital routines that make it difficult for patients to sleep well. If you find yourself hospitalized, there are things you can do to improve the chances that you will get a better night’s sleep.
Probiotics are being promoted as a way for women to improve vaginal health, but unlike with the gut and digestion, there is almost no evidence for any benefit.
Eosinophilic esophagitis is an allergic inflammation of the esophagus that most typically develops as an allergic response to certain foods. The exact cause is unclear, but if left untreated it can lead to permanent scarring or narrowing of the esophagus.
Many people now wear smartwatches and other wrist-based devices, and use them to collect and track information about their sleep. But the algorithms that govern how the devices work are opaque, and there is no data comparing them to devices that sleep researchers use.
Prostate cancer screening with the prostate-specific antigen (PSA) test has been criticized for flagging too many slow-growing tumors that might never be life-threatening. But some men have inherited gene defects that boost their risk of developing prostate cancers that can be quite aggressive. Is PSA screening particularly well-suited for these genetically defined groups? New research […]
The first of a new class of medications for the treatment of migraine has been approved by the FDA. Lasmiditan works differently than existing medications, and does not cause blood vessels to narrow (a side effect that makes them unsuitable for those with vascular conditions).
Parents of adult children who are struggling with infertility experience complicated feelings, both for what their child is going through and for themselves. Knowing how to deal with these feelings can make the situation easier for everyone involved.
For decades, people with atrial fibrillation were prescribed warfarin to prevent blood clots.

Crohn’s disease is a chronic, lifelong inflammatory bowel condition that affects approximately 500,000 Americans. It typically alternates between flare-ups and periods of remission. Dietary and lifestyle changes can help people manage the disease’s flare-ups.
Semantic memory is your store of factual knowledge and the meanings of words. It also helps you recall nonverbal concepts and relationships between words and concepts. And while some aspects of memory may decline with age, semantic memory does not.

Having trouble getting younger kids ready to leave home on time in the morning? Try these strategies to motivate them to accomplish morning-routine tasks.
An analysis of studies found an association between people with psoriasis and an increased risk of developing several types of cancer. While this does not establish a definitive link, psoriasis is a relatively common condition and those who have it should be aware of its implications.
Preeclampsia is a dangerous condition marked by hypertension that affects some women during late pregnancy or early weeks after birth. Rising rates of high blood pressure and maternal age increase risk for it. A recent study finds monitoring blood pressure at home may help.
Decisions about follow-up care after prostate cancer surgery sometimes involve a basic choice. If the cancer had features that predict it could return, doctors will likely recommend radiation therapy. But when should a man get that treatment? Should he get the radiation right away, even if there’s no evidence of cancer in the body (this […]
People who have elevated blood pressure readings in a doctor’s office but normal readings elsewhere are said to have white-coat hypertension. A new study suggests that people with this condition face a greater risk of heart disease than those whose blood pressure is always normal.
