Study reveals long-term survival benefits of gastric bypass surgery in patients with severe obesity

Patients with severe obesity who have gastric bypass surgery reduce their risk of dying from obesity and other diseases by 48 percent up to 10 years after surgery, compared to similar patients who do not undergo the procedure, according to new research presented today at ObesityWeek 2016, the largest international event focused on the basic science, clinical application and prevention and treatment of obesity.

Bariatric surgery becomes safer in accredited surgical centers, research shows

Patients who have weight-loss operations at nonaccredited bariatric surgical facilities in the United States are up to 1.4 times likelier to experience serious complications and more than twice as likely to die after the operation compared with patients who undergo these procedures at accredited bariatric surgical centers, researchers conclude.

New supplement could help reduce urge to consume high-calorie foods

Eating a type of powdered food supplement, based on a molecule produced by bacteria in the gut, reduces cravings for high-calorie foods such as chocolate, cake and pizza, a new study suggests.

Study shows subcutaneous fat tissue has internal clock that regulates insulin sensitivity

Fat tissue shows a robust circadian rhythm in a dish.In humans, glucose tolerance varies with time of day, but the mechanism responsible for the variation in insulin sensitivity throughout the day is unclear.

PYY hormone may offer effective treatment for type 2 diabetes

Researchers at the Norwegian University of Science and Technology and Oxford University have found a hormone that may offer an effective treatment for type 2 diabetes.

Health benefits of gastric bypass surgery start soon after procedure

The health benefits of Roux-en Y gastric bypass surgery—a surgical weight-loss procedure in which the stomach is made smaller—start soon after the procedure. New research presented today at the Experimental Biology 2016 meeting in San Diego found that patients who underwent the procedure already showed some reductions in weight, waist circumference and body mass index one week after the procedure.

Gastric bypass surgery cuts patients' healthcare costs by nearly 40%, study finds

A new study based on national insurance claims in the United States found that patients with obesity who had gastric bypass surgery cut their healthcare costs by nearly 40 percent after four years, and by 80 percent, if they also had type 2 diabetes before surgery.

Insulin sensitivity of main glucose storage sites in the body improve following gastric bypass surgery

Roux-en-Y, the most common type of gastric bypass surgery, can lead to remission of type 2 diabetes along with weight loss. A new study in the American Journal of Physiology—Regulatory, Integrative and Comparative Physiology examines why, finding that insulin sensitivity of the main glucose (sugar) storage sites in the body improve after gastric bypass surgery.

Gastric bypass surgery enhances energy expenditure

Gastric bypass surgery often leads to a sustained weight loss. Researchers at Sahlgrenska Academy have found part of the explanation: the operation enhances energy expenditure such that eating actually helps the person lose weight.

New study to explore mechanisms responsible for taste changes following RYGB, diet-induced obesity

Currently, one of the most effective surgical methods for treating obesity is the Roux-en-Y gastric bypass surgery, which limits the amount of food and drink that can be ingested at one time and the amount of calories and nutrients absorbed through the intestinal tract. An unintended side effect of RYGB is that it reduces the patient's taste for sweet and fatty foods—but there is no scientific explanation for why these taste changes occur.

Adjustable gastric band surgery, weight management program offer similar benefits in diabetes patients

Weight loss is never easy, but it's important for overweight people with type 2 diabetes seeking to control their blood sugar levels and optimize their health. A small clinical trial among such patients led by Joslin Diabetes Center and Brigham and Women's Hospital researchers now has shown that two approaches--adjustable gastric band surgery and an intensive group-based medical diabetes and weight management program--achieved similar improvements in controlling blood sugar levels after one year.
