How is bulimia nervosa diagnosed?

    Last Updated: October 25, 2023

    Bulimia is diagnosed when a person discloses typical binging or purging behavior to a healthcare provider. The provider then assesses their symptoms and medical history and conducts a clinical interview to make the diagnosis. According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) a person is considered to have bulimia nervosa if they binge at least once a week for 3 months. People with purging-type bulimia use vomiting, laxatives, diuretics, or enemas after binging, whereas those with nonpurging bulimia engage in other compensatory behaviors, like fasting or excessive exercise.[1][2]
