Abstract

Summary Atypical anorexia nervosa (AAN) is an eating disorder in which people who were previously higher or overweight experience body image disturbance and lose weight through unhealthy behaviors, resulting in weight loss, though patients may remain normal or above the normal weight range for age. In this article, we review the medical effects of AAN and how this unhealthy weight loss affects each organ system, and what is known about treatment.
