How Is Anorexia Diagnosed?

Identifying anorexia can be challenging. Secrecy, shame, and denial are characteristics of the disorder. As a result, the illness can go undetected for long periods of time.

If symptoms are present, the doctor will begin an evaluation by performing a complete medical history and physical exam. Although there are no lab tests to specifically diagnose anorexia, the doctor might use various diagnostic tests, such as blood tests, to rule out physical illness as the cause of the weight loss, as well as to evaluate the effects of the weight loss on the body's organs.

If no physical illness is found, the person might be referred to a psychiatrist or psychologist, health care professionals who are specially trained to diagnose and treat mental illnesses. Psychiatrists and psychologists may use specially designed interview and assessment tools to evaluate a person for an eating disorder.
