Anorexia Nervosa is an eating disorder and a psychiatric illness, belonging to a group of conditions known as eating disorders. This condition is characterized by an intense fear of gaining weight, and an extreme and persistent restriction of caloric intake. People with anorexia nervosa may also engage in excessive exercise, purging behaviors such as self-induced vomiting, and/or the use of diet pills and laxatives to control their weight.
The exact cause of anorexia nervosa is unknown, but biological, psychological, and environmental factors are believed to play a role. People with anorexia nervosa typically have a distorted body image, and may be preoccupied with a fear of gaining weight. In addition, they may have an intense need for control, and may be perfectionists. Low self-esteem, depression, anxiety, and difficulty expressing emotions may also contribute to the development of the disorder.
Anorexia nervosa is a serious and potentially life-threatening illness that can have serious medical complications. Treatment typically involves a combination of psychotherapy, nutrition counseling, and medical monitoring. If left untreated, anorexia nervosa can lead to severe medical complications, including heart problems, kidney failure, bone loss, and even death.
