Memory slips are aggravating, frustrating, and sometimes worrisome. When they happen more than they should, they can trigger fears of looming dementia or Alzheimer’s disease. But there are some treatable causes of forgetfulness.

New studies shed light on the role of aspirin for people without a previous heart attack or stroke.

It costs just pennies per pill, doesn't require a prescription, and may be lifesaving for some people. But daily low-dose aspirin doesn't make sense for everyone. Now, three major studies that examined the benefits and risks of this widely used drug may alter the advice about who should take aspirin.

"Aspirin remains a cornerstone of treatment after a heart attack or stroke. But the question of whether people with a low to moderate risk of heart disease should take aspirin is a really important one," says Dr. Christopher Cannon, a cardiologist at Brigham and Women's Hospital and professor of medicine at Harvard Medical School. Tens of millions of people in the United States fall into that low-to-moderate-risk category. But until now, there weren't many large trials that included those people, he notes.

Dozens of states are cracking down on the amount of opioids doctors can prescribe.

Overdoses of powerful painkillers called opioids kill more than 115 people per day in the United States. More than 42,000 people died from opioids in 2016, five times more than in 1999. The reason? Since several of these powerful painkillers became available in pill form several decades ago, doctors have been prescribing more than patients need. "It is estimated that a large part of leftover opioids are diverted to the street, either deliberately or through theft," says Dr. Edgar Ross, senior clinician at the Pain Management Center at Harvard-affiliated Brigham and Women's Hospital.

The misuse of opioids is a risk many states are no longer willing to take. The rules limit the amounts that medical professionals can prescribe for temporary (acute) pain from surgery, injury, or illness.

Postprandial hypotension, low blood pressure that occurs after eating, can cause dizziness, chest pain, nausea, or other issues, particularly in the elderly.

Trans fats and saturated fats can raise LDL cholesterol levels. A diet rich in unsaturated fats, whole grains, and fruits and vegetables can lower them.

Findings from a follow-up on people taking the weight-loss medication Belviq showed a slight increase in the occurrence of cancers, resulting in the drug being withdrawn from the market at the request of the FDA.

The growing field of health and wellness coaching uses motivational techniques and positive psychology to offer people individualized support as they work to achieve their health goals.

Some drugs that contain ranitidine (best known as Zantac) have been found by the FDA to have unacceptable amounts of N-nitrosodimethylamine (NDMA), a possible cancer-causing chemical (which also triggered recalls of certain lots of the blood pressure drugs called angiotensin-receptor blockers).

On April 1, 2020, the FDA requested that all forms of ranitidine (Zantac, generic versions), including prescription and over-the-counter products, be removed from the market. They may contain unacceptable levels of a potential cancer-causing substance known as NDMA, or N-Nitrosodimethylamine. In some samples tested by the FDA, the impurity appears to increase over time, especially when stored at higher temperatures. So far, tests of other acid blockers do not show this potential increased cancer risk.
