Anorexia Nervosa is the fear of gaining weight or becoming too fat when in reality the person is actually underweight.

Anorexia is a serious problem as it often deprives the body of essential vitamins and nutrients. Anorexia can be split into two groups;

  • The first involves bing-eating and purging
  • The other is a restricting type whereas the person does not involve oneself in eating and self induced purging or misuse of laxitives or enemas

In medicine, anorexia is the symptom of diminished appetite or appetite loss. The eating disorder anorexia nervosa is commonly referred to simply as “anorexia” in lay terminology.

Anorexia is one of the major etiologies, or causes, of malnutrition. Common disorders that cause anorexia include anorexia nervosa, severe depression, cancer, dementia, AIDS, and chronic renal disease.

Anorexia may also be seen in heart failure, perhaps due to congestion of the liver with venous blood.

Although the presenting symptom (the one which prompts a patient to seek medical attention) in acute appendicitis is abdominal pain, the presence of anorexia is requisite to making the diagnosis.
