Rumination is an eating disorder where an individual will chew, swallow and then regurgitate food back into their own mouth in order to re-chew it or spit it out. Rumination can be involuntary or voluntary with some ruminators enjoying the process.Â
The side effects of Rumination can be minor or life threatening. Some of the side effects include weight loss, tooth decay, bad breath, frequent stomach aches or indirection, chapped lips, electrolyte imbalance and inhalation of food which can lead to pneumonia.
