Diagnosis

Eating disorders are diagnosed based on signs, symptoms and eating habits. If your doctor suspects you have an eating disorder, he or she will likely perform an exam and request tests to help pinpoint a diagnosis. You may see both your primary care provider and a mental health professional for a diagnosis.

Assessments and tests generally include:

• Physical exam. Your doctor will likely examine you to rule out other medical causes for your eating issues. He or she may also order lab tests.
• Psychological evaluation. A doctor or mental health professional will likely ask about your thoughts, feelings and eating habits. You may also be asked to complete psychological self-assessment questionnaires.
• Other studies. Additional tests may be done to check for any complications related to your eating disorder.

Your mental health professional also may use the diagnostic criteria in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published by the American Psychiatric Association.
