Bulimia Nervosa is a serious psychiatric illness characterized by persistent binge eating (usually starches and sweets) and then inappropriate weight control. The most common type of inappropriate weight control is vomiting or the use of laxatives and/or diuretics. The person may also restrict food intake by fasting for several days after a binge. Or the person might excessively exercise in order to compensate for the high amount of calories ingested. In any case, Bulimia should be taken seriously and treated aggressively, as quickly as possible.
Many people wonder what constitutes a binge. Parents come into my office all the time asking if their child has a problem because they see large quantities of food eaten and no indications of weight gain. If your child is binging on food, two things will be true. First, she/he consumes much more food than most people would in a similar circumstance and in a similar period of time. In other words, eating large quantities of food during Thanksgiving dinner wouldn’t necessarily be considered a Bulimic binge. However, eating an entire box of cereal, a large pizza, or finishing off an entire birthday cake by oneself in a short period of time on a random Monday afternoon after school would constitute a binge.
In addition, when the person is engaged in the binging behavior, she/he feels very much out of control. My patients often state things like “I couldn’t stop myself,” or “It was as if I was driven by a motor.” This is perhaps one of the most distressing parts of this illness—the feeling of being out of control. Imagine a teenager who leaves school, goes to McDonalds, orders a meal deal, then stops by an ice cream shop and gets a double sundae. Next he/she goes home and if the stomach is not completely full yet (it expands with the large quantities it takes in), he/she finds something else to consume. Due to physical discomfort, fear, or even disgust, the person then rids himself or herself of the food—usually by purging.
In order to be formally diagnosed with Bulimia, both of the behaviors mentioned above (binge eating and inappropriate weight control) have to occur at least twice a month for at least three consecutive months. As a warning, I tell parents that if their child is engaging in these behaviors even on an irregular basis, act fast to get her/him into treatment. Bulimia can be highly habit forming.
