Here's another good reason to lose weight: It might benefit your friends, family and co-workers. Such altruism might be just the final "nudge" some of us need.

Researchers are finding that the friends and family of obese and overweight individuals who lose weight lost weight themselves, and sometimes a lot of it. Dr. John Morton, who directs Bariatric Surgery at Stanford Hospital & Clinics, calls obesity a "family disease."

Parents and doctors around the world have been alarmed by the dramatic increase in childhood asthma.

One factor in the upswing is better detection by doctors, but at least one doctor thinks a common over-the-counter drug also has something to do with it.

Tai chi, the Chinese martial art involving slow and rhythmic movement, has been shown to benefit older people by maintaining balance and strength. Now, researchers have found that tai chi also helps patients who suffer from Parkinson's disease.

Leona Maricle was diagnosed with Parkinson's two years ago. At the time, she was teaching math, and she says she had experienced the telltale tremors of Parkinson's for a number of years. She learned how to cope.

Access to emergency contraception has swirled at the center of a recent flurry of debate over insurance coverage. It's a pill women can take if their birth control fails or they forget to use it.

The most popular brand of emergency contraception is called "Plan B One-Step." You might better know it as the morning-after pill. Today, about 10 percent of sexually active women say they've used it.

Heart disease remains the leading cause of death in the U.S. But who's at the most risk?

A study in the lastest New England Journal of Medicine offers a simple way to predict the risk of a fatal or debilitating heart attack or stroke for a middle-aged person over the rest of his or her life.

Most patients who undergo bariatric surgery lose weight and experience other health benefits. They have less heart disease, diabetes and cancer than their obese counterparts who don't have the surgery.

Now, researchers from the University of Gothenburg in Sweden find bariatric surgery also reduces deaths from cardiovascular causes, such as heart attacks and strokes.

If you're the parent of a teenager, you likely find yourself routinely embroiled in disputes with your child. Those disputes are the symbol of teen developmental separation from parents.

It's a vital part of growing up, but it can be extraordinarily wearing on parents. Now researchers suggest that those spats can be tamed and, in the process, provide a lifelong benefit to children.
