Refusal to maintain body weight at or above a minimally normal weight for age and height. (This includes a failure to achieve weight gain expected during a period of growth leading to an abnormally low body weight.)

Intense fear of weight gain or becoming fat.

Distortion of body image (e.g., feeling fat despite an objectively low weight or minimizing the seriousness of low weight).

Amenorrhea. (This criterion is met if menstrual periods occur only following hormone — e.g., estrogen — administration.)
