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.

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.

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.
