"Diabulimia" is a relatively new term for the tampering or reducing of insulin intake to lose weight. It blends "diabetes" and "bulimia," but the term itself is misleading; diabulimia does not necessarily reflect the binge eating and purging that characterizes bulimia nervosa. Experts say it can take many forms. Some people wrestling with it might eat completely normally but reduce their insulin, so their body does not absorb the calories they consume. Some, like Russell, might go through the motions of injecting insulin, or freeze or heat it to make it less effective, so the people around them don't notice different behavior, other than sudden weight loss and often a heightened interest in body image. Other symptoms might include trouble sleeping, increased thirst and exhaustion. Learn more.
