Rumination
Introduction
Rumination is the (usually involuntary) regurgitation of small amounts of food from the stomach (most often 15 to 30 minutes after eating) that are rechewed and, in most cases, again swallowed. Patients do not complain of nausea or abdominal pain. Rumination is commonly observed in infants. The incidence in adults is unknown, because it is rarely reported by patients themselves.
