Gastric Bypass Risk And Binge Eating


There has long been a debate over whether binge eating presents a gastric bypass risk and increases the possibility of a poor outcome following surgery. A recent report published in the Journal of Clinical Psychiatry may however shed new light on this argument.
The study carried out at the Yale University School of Medicine involved nearly 140 extremely obese patients and looked at their eating habits prior to surgery and then followed them up during the twelve months after gastric bypass surgery.
Of the study group, some 40 patients reported binge eating in the month before their operation and approximately ten percent of the study group were classified as meeting the criteria to be diagnosed as having binge eating disorder. It was also noted that those people classed as binge eaters were considerably more nervous about their impending surgery than the non-binge eaters.
Following surgery the study noted that there was no difference of note between the two groups and that both binge eaters and non-binge eaters showed virtually identical weight loss profiles in the twelve months after their gastric bypass.
Prior to surgery the average body mass index was 51.7, placing the group well over the body mass index figure of 40 which defines extreme, or morbid, obesity. One year after surgery this figure had fallen to just 33.3, bringing many of those in the study group close to a normal body mass index.
