Abstract
Eating disorders (EDs) are abnormal and pathological eating habit, leading to many psychiatric and somatic complications and thus constitute a major public health problem. There are many forms of EDs, which are described in the Diagnostic and Statistical Manual of Mental Disorders (DSM). Anorexia nervosa (AN) is common in adolescence, especially in girls. Due to intense fear of weight gain, an individual avoids high caloric diet and induces repeated vomiting, leading to emaciation, hypokalemia, alkalosis, and fluid and electrolyte imbalance. Bulimia nervosa (BN) is characterized by recurrent bouts of binge eating in a short period of time. Binge eating is followed by self-induced vomiting and use of laxative and purgative. Complications of the patients suffering from AN and BN occur due to hypokalemia, alkalosis, and electrolyte imbalance. Eating disorder not otherwise specified (EDNOS) is more or less identical to BN. Binge eating disorder (BED) is different from BN as episodes of binge eating are not followed by purging, fasting, and vigorous exercise. BED patients lose control over his or her eating and become obese due to hyperphagia. EDs are also common during childhood, pregnancy and in Type 1 diabetes mellitus.
