Eating disorders are serious behavioural problems. A person who suffers from eating disorders follows eating patterns that can seriously damage his/her health. The common causes and symptoms of this disease include excessive concern about their weight, a distorted view of the body and low self-esteem. The most common eating disorders are anorexia and bulimia nervosa. When a person suffers from anorexia, he/she avoids eating and/or takes laxatives and diuretics. In addition to this, the person may also do intense physical exercise, which could endanger her/his life. The main characteristic of bulimia is that people do binge eating, followed by purging or self-induced vomiting to eliminate and compensate for overeating. All this with a sense of guilt. In these cases, the emergency treatment of patients through a comprehensive plan that includes psychotherapy and continuous monitoring is crucial. In severe cases, the admission of patients to a specialised centre for treatment may be necessary.
