Clinical overview

• Bulimia nervosa usually looks like a painful cycle of binge eating followed by attempts to undo the binge through purging, fasting, overexercise, or other compensatory behaviors. Shame, secrecy, and shape-weight overvaluation are often central to how the illness is experienced.
• Binge plus compensation: Both parts matter. The diagnosis requires loss-of-control binge episodes and compensatory behavior afterward.
• Frequency threshold: The pattern has to be recurring, not occasional. DSM threshold is at least weekly for 3 months.
• Differential: One of the main distinctions is whether the person is currently at significantly low weight, which may shift the frame toward anorexia nervosa.
