label_lc: rumination disorder
description: Rumination disorder is the backward flow of recently eaten food from the stomach to the mouth. The food is then re-chewed and swallowed or spat out. A non-purposeful contraction of stomach muscles is involved in rumination. It may be initially triggered by a viral illness, emotional distress, or physical injury. In many cases, no underlying trigger is identified. Behavioral therapy is the mainstay of treatment.
