Print OverviewRumination 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.Products & ServicesBook: Mayo Clinic on Digestive Health Symptoms Effortless regurgitation, typically within 10 minutes of eating Abdominal pain or pressure relieved by regurgitation A feeling of fullness Bad breath Nausea Unintentional weight loss Rumination syndrome isn't usually associated with retching. When to see a doctorConsult a doctor if you or your child persistently regurgitates food. CausesThe precise cause of rumination syndrome isn't clear. But it appears to be caused by an increase in abdominal pressure. Rumination syndrome is frequently confused with bulimia nervosa, gastroesophageal reflux disease (GERD) and gastroparesis. Some people have rumination syndrome linked to a rectal evacuation disorder, in which poor coordination of pelvic floor muscles leads to chronic constipation. The condition has long been known to occur in infants and people with developmental disabilities. It's now clear that the condition isn't related to age, as it can occur in children, teens and adults. Rumination syndrome is more likely to occur in people with anxiety, depression or other psychiatric disorders. ComplicationsUntreated, rumination syndrome can damage the tube between your mouth and stomach (esophagus).
