This occurs when a person (usually a young woman) with type 1 diabetes manipulates the amount of insulin they normally take and the amount of food they normally eat in order to loose weight. This is extremely dangerous, and doctors are finding out that between 10 to 15 percent of adolescent diabetics suffer from severe diabulimia. If a person is diabulimic for a relatively short time, he or she is at risk for ketoacidosis, or the build-up of acids in the bloodstream, that can lead to diabetic coma or death.
