Food Rumination Syndrome

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.
