Hormone Release and Stomach Disturbances in People With Binge Eating Disorder
Postprandial Cholecystokinin Release and Gastric Emptying in Binge Eating Disorder

This study will determine whether the disturbances in cholecystokinin release and gastric emptying that occur in people with binge eating disorder are similar to those that occur in people with bulimia nervosa.

Binge Eating Disorder (BED) is a serious eating disorder that can occur in people of any weight, but occurs most frequently in people who are overweight. BED is characterized by the following eating behaviors: frequent episodes of eating large quantities of food in short periods of time; feeling out of control over one's eating behavior; feeling ashamed or disgusted by one's eating behavior; eating when not hungry; and eating in secret. BED is similar to Bulimia Nervosa (BN), in that binge eating is a characteristic of both disorders. However, people with BED do not purge after an episode of binge eating, and therefore often become overweight. The health risks of BED include those that are most commonly associated with clinical obesity. High blood pressure, high cholesterol levels, heart disease, diabetes mellitus, and gallbladder disease are all health problems that occur frequently in people with BED. CCK is a hormone that is released by the small intestine, and functions as a trigger for digestion and hunger suppression. People with BN often have disturbances in the release of cholecystokinin (CCK), which may contribute to their binge eating behavior. This study will determine whether the disturbances in CCK release and gastric emptying that occur in people with BED are similar to those that occur in people with BN.

Participants in this study will report to the study site on two non-consecutive days within a 2-week period for gastric emptying testing. On the day before the first study visit, participants will be instructed to eat a standardized dinner that does not include alcohol before 7 P.M., and not to eat or drink after 9 P.M. On the first day of testing, participants will lie in a semi-reclined position while drinking 600 ml of Ensure Plus. A gamma camera will be placed over the stomach to measure gastric emptying. In addition, a catheter will be inserted into the forearm of all participants for periodic blood testing throughout the process. On the second day of testing, participants will perform the same procedures, but the Ensure Plus will also contain a small amount of radioactive material so that gastric emptying can be tracked by the gamma camera. The testing procedure on each day will take approximately 90 minutes.
