People with eating disorders can suffer from oral health problems as well. This is because many of the behaviors associated with anorexia nervosa and bulimia nervosa—such as binge eating, self-induced vomiting, and use of diuretics or laxatives—cause changes in the mouth. For example, repeated episodes of vomiting, which is common in people with bulimia, release harmful stomach acids that pass through the mouth and can erode tooth enamel, causing cavities, discoloration and tooth loss.
