Bulimia Nervosa
Bulimia Nervosa is described as a disorder in which frequent episodes of binge eating (rapid consumption of food in one sitting) are almost always followed by purging (ridding the body of food). Purging can involve vomiting, abusing laxatives and/or diuretics, exercising compulsively and/or fasting. Binging and purging is often followed by intense feelings of guilt and shame. Those suffering with bulimia may not be visibly underweight and may even be slightly overweight. As in anorexia nervosa, bulimia nervosa may use self-destructive eating behaviors to deal with psychological problems that may go much deeper than her/his obsession with food and weight. Usually, the individual feels out of control and recognizes that the behavior is not normal. Up to 5% of college women in the U.S. are bulimic.
Research on Zofran®
One of the studies conducted by our eating disorders research group at the University of Minnesota has found that the drug Zofran®, which is traditionally used to combat nausea induced by chemotherapy, shows considerable promise in the treatment of bulimia nervosa. Patients involved in this study had to be diagnosed as suffering from sever bulimia. This meant patients had binge/vomit episodes greater then seven times per week with some patients having episodes up to 25 times per week. Most patients had exhibited the behaviors for more than 5 years and had a feeling of loss of control over the symptoms.
In the study 26 women with bulimia nervosa were randomly placed in one of two groups, no drug (placebo) or drug (Zofran®). After an initial baseline and placebo week, patients in the no drug group received a placebo pill while patients in the drug group received Zofran®. Throughout the subsequent four weeks, the number of binge/vomit episodes was measured in both groups. At the end of the study we found that the number of binge/vomit episodes dropped significantly in the group being treated with Zofran® when compared to the placebo group.
Since the end of the study period there have been several patients that haven’t binged/vomited for up to seven years, while others have cut the number from as many as seven times a day down to once or twice a day.
