Anorexia Nervosa Definition

Anorexia nervosa or anorexia is a complex eating disorder characterized by an abnormally low body weight, irrational fear of gaining weight and a distorted perception of body weight altogether.

Anorexia is an obsessive condition where people take extreme to control their body weight so much so, that it begins to interfere with important aspects of their lives. These measures may include strictly restricting their food intake, reducing their calorie intake or by misusing diuretics, laxatives diet aids or enemas.

Often, anorexia is looked at an unhealthy way to cope with emotional problems, rather than the problem lying in eating itself.

Anorexia Nervosa Diagnosis

If your doctor thinks you may be suffering from anorexia, he/she will run a number of tests and exams to confirm the prognosis and rule out any other possibilities that may cause excessive weight loss. These tests and scans may include:

Physical Exam

In a physical exam, the doctor might check your vital signs and measure your height and weight.

Lab Tests

Lab tests may include a complete blood count (CBC) and specialized blood tests to check electrolytes and functions of organs such as the liver and kidney.

Other tests may include a full psychological evaluation, X-Ray, bone density tests, etc.

Anorexia Nervosa Treatment

Treatment for anorexia may range for hospitalization for medical complications such as dehydration, electrolyte imbalance or psychiatric emergencies.

Having family members around who can help restore confidence and ensure the patient gets back to a healthy weight can be very helpful.

Psychotherapy is another way of treating anorexia as it will address the emotional and behavioural problems that one may be facing.

Alternative treatment such as yoga, meditation, massage may also help.
