Rumination Disorder
Key Points
Rumination is repeated regurgitation of food after eating but does not involve nausea or involuntary retching. Some patients with rumination disorder are aware that the behavior is socially unacceptable and try to disguise or hide it. Some limit how much they eat (to prevent others from seeing them regurgitate), sometimes resulting in weight loss or nutritional deficiencies. Diagnose rumination disorder in patients who report repeatedly regurgitating food for≥1 month after excluding other possible causes (eg, GI disorders, other eating disorders). Treat using behavioral modification techniques.
