What is bulimia nervosa?

    Last Updated: October 25, 2023

    Bulimia nervosa (BN), also called bulimia, is a type of eating disorder characterized by eating a lot of food in a short amount of time while feeling out of control (binge eating) followed by feelings of disgust that lead a person to purge with vomiting, laxatives, excessive exercise, fasting, or diuretics to prevent weight gain.

    Binging and purging can lead to stomach damage, dehydration, electrolyte imbalances, tooth decay, throat ulcers, menstrual irregularities, and intestinal problems. Teen girls and young women are at greatest risk of developing BN, but it can occur in all genders, races, and ages.[1][2]
