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.

MGH investigators report that medication could augment benefits of bariatric surgery

New findings about the mechanisms involved - or not involved - in the effects of the most common form of bariatric surgery suggest that combining surgery with a specific type of medication could augment the benefits of the procedure. In a report that has been published online in the journal Endocrinology, Massachusetts General Hospital investigators report that the effects of Roux-en-Y gastric bypass (RYGB) do not utilize neurologic pathways controlled by the serotonin 2C receptor.

Small intestine causes chronic inflammation in obese patients

Obesity is caused by numerous and complex factors, some of which are as yet unsuspected. Scientists from the CNRS, INSERM, UPMC and Université Paris Descartes, working with research clinicians from Paris Public Hospitals (AP-HP) have now shown that severe obesity is accompanied by inflammation of the small intestine and enhanced immune response in that region.

Medtronic's new GastriSail gastric positioning system combines benefits of three devices into one

Furthering its commitment to fight obesity with innovative bariatric surgical solutions, Medtronic now offers the GastriSail(TM) gastric positioning system to help promote more consistent sleeve creation and greater procedural efficiency(1) within the sleeve gastrectomy procedure, the most commonly performed weight loss procedure in the U.S.

Study explores non-biological factors that may cause fewer men to seek bariatric surgery

A new study by researchers at the University of California, San Diego School of Medicine has identified demographic, socioeconomic and cultural factors that contribute to a major gender disparity among U.S. men and women undergoing weight loss surgeries. Men undergo the surgeries in far lower numbers than women.

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.

Gastrointestinal colonization with methanogens increases difficulty of losing weight after bariatric surgery

A new study finds that after weight loss surgery, people whose breath has high concentrations of both hydrogen and methane gases have a lower percentage weight loss than other bariatric surgery patients do. The study results will be presented Thursday at the Endocrine Society's 97th annual meeting in San Diego.

Experts question value of current obesity treatments

Many people with obesity can lose weight for a few months, but 80%–95% regain their lost weight eventually. One explanation for this limited long-term success is that reducing caloric intake triggers several biological systems that drive us to eat high-calorie foods and gain weight.

Study suggests that gastric bypass should be used with caution to treat extreme obesity

Based on five-year follow-up of patients in a randomized clinical trial, researchers have concluded that gastric bypass is the preferred treatment for extreme obesity. This is despite the fact that it is not as effective in reducing body weight as the so-called duodenal switch.
