Anorexia nervosa is a disorder characterized by deliberate weight loss, induced
and/or sustained by the patient. The disorder occurs most commonly in
adolescent girls and young women, but adolescent boys and young men may be
affected more rarely, as may children approaching puberty and older women up
to the menopause.
Bulimia nervosa is a syndrome characterized by repeated bouts of overeating and
an excessive preoccupation with the control of body weight, leading the patient to
adopt extreme measures so as to mitigate the “fattening” effects of ingested food.
Binge Eating Disorder (BED) is commonly known by compulsive overeating or consuming abnormal amounts of food while feeling unable to stop and at loss of control. Binge eating episodes are typically classified as occurring on average a minimum of twice per week for a duration of six months.
