Weight-loss surgery clearly cuts the risk of heart attacks, strokes and death from cardiovascular disease, a new study shows. But the research also raises questions regarding which patients benefit the most from surgery. The study, published Tuesday in the Journal of the American Medical Assn. , is the first controlled clinical trial to measure the impact of bariatric surgery on heart health. The Swedish Obese Subjects study compared 2,010 middle-aged, obese people who had weight-loss surgery with 2,037 similar obese people who received normal medical care, which usually included counseling on lifestyle choices that affect weight.

In its potential to fight Type 2 diabetes, bariatric surgery is looking good -- very good. Bariatric surgeons themselves noticed the operation's potential some time ago, as these earlier stories noted: Gastric bypass: Is it a diabetes fix? Weight-loss surgery may soon be widely used Then other studies began to confirm the operation's ability to help patients quickly get control of their disease. Now we have a study, published Monday in Archives of Surgery, analyzing diabetes-drug use and healthcare costs in the wake of bariatric surgery.

While diet and exercise are available to all, bariatric surgery is likely to remain a solution available to just a small fraction of the 90 million Americans who are obese. But when it comes to inducing weight loss and improving obesity-related health conditions, a new study has found that there really is no contest between the two: Procedures such as gastric bypass, sleeve gastrectomy and gastric banding beat diet and exercise. By a long shot. A new study published Tuesday in the British Medical Journal finds that among subjects followed for at least six months and as long as two years, those who got weight-loss surgery lost on average 57 more pounds than those in nonsurgical weight programs.

Alcohol can be a minefield for anyone trying to lose weight. But for bariatric surgery patients, drinking can become increasingly problematic, a new study has found. Changes in the way the body absorbs and metabolizes alcohol after gastric bypass mean these patients need less alcohol to register intoxication on a breathalyzer, says a study published recently in the Journal of the American College of Surgeons . After drinking a single 5-ounce glass of red wine before their surgery, the study's 19 subjects had an average breath alcohol content of .024% -- well below the level at which most states consider a driver intoxicated.

More than 120,000 obese Americans had some kind of surgery to help them lose weight in 2004, with the biggest increase among middle-aged people, according to a study released Wednesday. In 1998, 772 people age 55 to 64 had gastric bypass, stapling or some similar procedure known as bariatric surgery to help weight loss. But that number ballooned to 15,086 in 2004, the Agency for Healthcare Research and Quality reported.

Americans love to look good, but insurers are often reluctant to pay the bills to help us look better. Last year we spent nearly $11 billion on cosmetic procedures, according to the American Society for Aesthetic Plastic Surgery. Of the more than 10 million procedures performed, the most requested was breast augmentation. But Cameo Wichinsky, a 42-year-old investment fund manager living in Santa Monica, wants to take her figure in the opposite direction. Having long lived with the discomfort of breasts large enough to cause shoulder and neck pain and to limit her level of physical activity, she's ready to go under the knife to reduce her breast size and, she hopes, improve her quality of life.

The weight loss that follows a successful bariatric surgery makes most patients feel younger. But a new study suggests that following bariatric surgery, some patients show signs of being biologically younger, as well. At Stanford University, researchers looked for evidence of change in bariatric surgery patients by measuring their telomeres -- regions of repeating DNA sequences at the end of a chromosome that grow a little shorter with age and chronic illness. Telomeres are considered a biomarker of the aging process.

Weight-loss surgery for morbidly obese adolescents has become more popular even though many questions about safety and effectiveness remain, according to a commentary published Wednesday in the New England Journal of Medicine . Until more is known about the long-term effects of such surgery, stringent requirements to qualify for the surgery should remain in place, said the author of the report. Weight-loss, or bariatric, surgery is much more common among adults, and studies show it produces many benefits for most patients.

Gastric bypass surgery for weight loss is as safe for the elderly as it is for younger patients, researchers said Monday. Several small studies reported previously have yielded mixed results about safety in those over 65, but a new study on a much larger group of patients finds no increased risk from the procedure. Elderly patients do end up spending more time in the hospital after the surgery, however, said Dr. Robert B. Dorman of the University of Minnesota at a Digestive Diseases Week meeting in Chicago.

News from the Obesity Society annual meeting in San Diego: -- Doctors have tried inserting a balloon into the stomach to make a person feel full so he won't eat as much and will lose weight. Now scientists are turning to a similar strategy that involves swallowing a capsule. -- Researchers in Calgary reported Sunday that they had devised fake food, or pseudofood, to make people feel fuller. The method involved filling a gelatin capsule made of biocompatible and biodegradable materials with expandable, absorbent fiber and polymer granules.
