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.


Cluster Number:
Wiki Number: PW190
Diagnosis: (Food) Rumination Syndrome
US Patients: 10% of institutionalized infant or child mental disabilities
World Patients:
Sex Ratio: B;G+

Progression: Unlike normal vomit, the process is normal and unforced. Damage to the esophagus and alimentary canal, malnutrition, weight loss

    Rumination syndrome is a functional gastrointestinal disorder defined as the effortless regurgitation of recently ingested food from the stomach back into the oral cavity in the absence of organic disease. The regurgitation usually occurs within the first 15 minutes after the completion of a meal.
