Diagnosis of Eating Disorders
- 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 depression and 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.

A randomized trial found that drinking water before main meals led to higher weight loss than those who were asked to imagine a full stomach before main meals. Water preloading is believed to help create a feeling of fullness or satiety during the meal, which may help curb overeating.
