Overview

Rumination syndrome is a condition in which people repeatedly and unintentionally spit up (regurgitate) undigested or partially digested food from the stomach, rechew it, and then either reswallow it or spit it out.

Because the food hasn't yet been digested, it reportedly tastes normal and isn't acidic, as vomit is. Rumination typically happens at every meal, soon after eating.

It's not clear how many people have this disorder. Treatment may include behavioral therapy or medications. Behavioral therapy that involves teaching people to breathe from the diaphragm is the usual treatment of choice.
