The first step in being diagnosed is admitting that you have symptoms of an eating disorder. You may need support and encouragement from others before seeking help.
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.
As part of the overall evaluation, your doctor will: Give you a physical exam and check your height and weight.Check the back of your teeth for erosion if you have symptoms of
bulimia. Erosion indicates frequent vomiting.Have your blood, urine, and other fluids tested to evaluate your overall health.Get x-rays
to check for bone thinning.
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-5). In addition: 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.Screening tests, such as the Eating Attitudes Test (EAT-26), can be used to screen for symptoms of eating disorders.
