It's no secret that excess weight is bad for the heart. But a new study suggests that obese people who lose a substantial amount of weight may reverse the related cardiovascular risks.

Researchers found the odds for high blood pressure and elevated cholesterol were similar in formerly obese Americans who were now at a healthy weight and people who had always had a healthy weight.

Severely obese children who are unable to slim down should be eligible for weight loss surgery, a new study suggests.

The gastric sleeve procedure is safe and effective long-term, said a research team that followed participants as young as 5 for a decade.

Obese boys who lose weight may avoid fertility problems in adulthood, a preliminary study suggests.

Even short-term weight loss might partially reverse weight-related alterations in reproductive function, the researchers said.

Shedding excess weight does much more for the long-term heart health of young people than building muscle, new research suggests.

It's not that gaining muscle while young proved to be a cardiovascular problem. It's just that losing fat offered bigger heart benefits.

"We absolutely still encourage exercise," said study lead author Joshua Bell, a senior research associate in epidemiol...

Twenty years on from the terrible event itself, weight loss may reduce the risk of lung disease among 9/11 first responders, a new study suggests.

"Our findings should reassure World Trade Center first responders that there are steps they can take to protect their lungs even decades after exposure," said co-lead author Dr. Sophia Kwon. She's a fellow in the Division of Pulmonary, Critical...

Seniors, it may be easier than you think to undo the damage of decades of bad eating and precious little exercise.

New research shows that cutting just 250 calories a day and exercising moderately could lead to not only weight loss but improved vascular health in older obese adults.

These lifestyle changes may help offset age-related increases in aortic stiffness, which is a measure...

Weight-loss surgery can be a double-edged sword for obese women who want to shed pounds before becoming pregnant: New research shows it lowers the risk of some complications, but it may increase the risk of others.

Investigators followed more than 20,000 women in California who became pregnant between 2007 and 2018. Of those, 9.3% had weight-loss (bariatric) surgery before their pregnanc...

Some people severely ill with COVID-19 may struggle to regain lost weight for months afterward, a new study shows.

While COVID-19 is primarily a respiratory illness, it's become clear that the infection can wreak havoc on the body in many ways. Gastrointestinal (GI) symptoms -- like nausea, diarrhea and even bleeding in the digestive tract -- are among the manifestations.

In some ca...

People with type 2 diabetes face heightened risks for heart attack and stroke, as well as progressive kidney disease. But a new once-a-week injected drug called efpeglenatide could greatly reduce their odds for those outcomes, new research shows.

The clinical trial was conducted in over 28 nations and involved more than 4,000 patients with type 2 diabetes.

Over two years, patients ...

Losing weight is hard, but many weight loss supplements promise to make the journey easy. Unfortunately, there's little high-quality research to back these claims, a new study shows.

Hundreds of weight loss supplements like green tea extract, chitosan, guar gum and conjugated linoleic acid are being hawked by aggressive marketers. And an estimated 34% of Americans who want to lose weight ...
