Document Summary
It has not always done so, but western society today equates thinness with health and beauty. There has been a rise in eating disorders in the past three decades. The core issue is a morbid fear of weight gain. A third disorder is on the rise: binge-eating disorder -- people frequently go on eating binges but do not force themselves to vomit or engage in other purging behaviours. The main symptoms of anorexia nervosa are: a refusal to maintain more than 85% of normal body weight, intense fears of becoming overweight, distorted view of weight and shape, amenorrhea -- inability to menstruate. There are two main subtypes: restricting type. Lose weight by cutting out sweets and fattening snacks, eventually eliminating nearly all food. At least half of people with anorexia nervosa reduce their weight by restricting their intake of food: binge-eating/purging type. Lose weight by forcing themselves to vomit after meals or by abusing laxatives or diuretics.
