Anorexia is a serious mental health condition in which the sufferer has a preoccupation with weight and body shape with a morbid fear of being ‘fat’ or an intense desire to be ‘thin’ and therefore an abnormally intense wish to keep the body weight as low as possible.
People with anorexia nervosa try to keep their weight low by restricting their food intake drastically, making themselves vomit and exercising excessively. A large proportion of the sufferers also have a distorted body image, believing that they are fat when in fact their weight is lower than normal healthy weight.
Anorexia mostly affects girls and women in late childhood or adolescence (with 10:1 Female: male ratio) and is commoner in the Western culture.
Unfortunately people with anorexia lose the insight into their mental health issues and therefore go to great lengths to hide their disorder from family and friends, and do not seek professional help for prolonged period of time.
