People with anorexia nervosa often have the following personality traits: perfectionism, low self-esteem, neuroticism, and social isolation. Symptoms of anorexia nervosa include the maintenance of body weight 15% (or more) below normal. This weight is achieved through unhealthy behaviors such as the avoidance of certain types of foods, engaging in excessive exercise, vomiting, and / or the use of laxatives.
Those who suffer from anorexia nervosa are typically scared of gaining weight and are preoccupied with their bodies. Health risks associated with anorexia nervosa include hormonal disturbances, constipation, diarrhea, tooth loss, no menstruation, osteoporosis, and damage to internal organs (heart, liver, kidneys, and brain). These health risks are severe and can result in death.
