Problem:
Kate reports to you that between one and three times a week, she comes home from work and eats a large amount of food, much larger than most people could eat in one sitting. She reports that she never means to eat that much, she just feels like once she starts, she can't stop herself from eating more. When she is done, in order to compensate for her large caloric intake, she makes herself vomit over and over until she feels like she has "gotten rid of it all." The whole process creates a great deal of shame for Kate. What disorder is Kate likely experiencing?
