The first step in diagnosis is admitting that you have symptoms of an eating disorder. You may need support and encouragement from others before seeking help. Initial evaluation—During the initial evaluation, your doctor will ask about your symptoms and medical history, the amount of food you eat, and how you try to control your weight.
Physical exam and tests—Your doctor will give you a physical exam and check your height and weight. If you have symptoms of
bulimia, your teeth may be checked for erosion, which is a sign of frequent vomiting. You will also have routine blood, urine, and other tests to check your overall health status.
Psychiatric evaluation—A mental health professional may perform a series of tests and evaluate you for other psychiatric conditions, such as
anxiety disorders, which are common in people with eating disorders. Diagnosis of a particular type of eating disorder is based on an evaluation of your symptoms using the criteria of the American Psychiatric Association’s
Diagnostic and Statistical Manual of Mental Disorders
(DSM-IV). Screening tests such as the Eating Attitudes Test (EAT-26) can be used to screen for symptoms of eating disorders.
