60% of Bariatric Patients Keep Weight Off

April 16, 2010 -- Nearly 60% of bariatric surgery patients are successful atlong-term weight loss, according to a new study from Switzerland with aneight-year follow-up.

However, disordered eating behaviors, such as binge eating or night eating,lingered for 51% of the 80 women who completed the entire study, says studyauthor Maaike Kruseman, MPH, RD, professor of nutrition and dietetics atthe University of Applied Sciences Western Switzerland, Geneva.

The weight loss results, however, were a pleasant finding for researchersand patients, Kruseman says. ''In our center, most patients have a long historyof failed diets, so successful weight loss lasting longer than a coupleof years was an incredibly good result," Kruseman tells WebMD in an emailinterview.

Disordered eating after the bariatric or weight loss surgery is not usuallydocumented on a routine basis, she says, but she suspects it is common. "Thebypass takes care of one aspect of the patient's problems, but if disorderedeating is present before the operation, it will not [usually] disappear byitself, or only rarely," she says.

That finding, she says, points to the need for long-term follow-up ofbariatric surgery patients by a team of health care providers that can tend tomedical and psychological needs.

The study appears in the Journal of the American DieteticAssociation.

Is Weight Loss Surgery Right for You?

Bariatric Surgery Study Initially, 141 patients (including 10 men) were enrolled in the study. Theaverage age was 40. At the study start, the average weight was 274 pounds andthe average body mass index (BMI) was 46.

Candidates for bariatric surgery have a BMI of 40 or above, according to theAmerican Society for Metabolic & Bariatric Surgery, or a BMI of 35 or morewith an obesity-related disease, such as type 2 diabetes or heart disease. ABMI of under 25 is deemed healthy.

All participants had the type of bariatric surgery known as the Roux-en-Ygastric bypass between 1997 and 2002. In the procedure, the gastric bypass isachieved by reducing the size of the stomach so that a small gastric pouch iscreated. The small pouch size leads to reduced food intake.

At the 8-year mark, 80 participants, all women, were still taking part inthe study. Of those, 47, or 59%, had achieved an excess weight loss of 50% ormore, considered successful.

At the end of the follow-up, researchers also found:

Fifty-three patients or 67% had a BMI under 40; 16 or 20% had shifted fromthe obesity category to overweight. One woman achieved a normal BMI, under25. The average daily calorie intake went from 2,355 at the study start to1,680 for the 80 participants who finished the study. Younger women were more likely to maintain the successful weight loss. http://www.webmd.com/diet/weight-loss-surgery/news/20100416/60-percent-of-bariatric-patients-keep-weight-off?src=RSS_PUBLIC
