Anorexia Nervosa: Symptoms & Signs

Anorexia nervosa is an eating disorder often characterized by a distorted body image. There is significant weight loss and difficulty maintaining an appropriate body weight. The exact cause of anorexia is not well understood, but it involves a combination of self-esteem and body-image issues, genetic factors, and societal pressures.

Symptoms of anorexia nervosa can include restricting food intake, compulsive exercise, overuse of laxatives, extreme weight loss, and preoccupation with weight, food, calories, and diet. Poor nutritional status and weight loss can also cause symptoms throughout the body. Examples of possible associated signs and symptoms are dizziness, constipation, feeling cold, sleep disturbances, irregular menstruation, muscle weakness, poor wound healing, thinning hair, damage to enamel of the teeth, delayed puberty, and difficulty concentrating.
