RUMINATION DISORDER, also known as rumination syndrome, is a rare and chronic eating disorder. Individuals with Rumination Disorder unintentionally and repeatedly regurgitate food before swallowing it again, chewing it once more or spitting it out. They often spit up food from their stomach; re-chew partially digested or undigested food unintentionally and either re-swallow or spit it out. As per the reports of the patients, since the food hasn’t yet been digested, it isn’t acidic, as vomit is and tastes normal. Rumination usually happens soon after eating, at every meal but it appears to be the result of increased abdominal pressure.
