Many disorders can affect the digestive system. Some are physiological, while others are physical conditions with a strong psychological component. Rumination syndrome is one of the latter. People with this condition unintentionally regurgitate undigested food. They then either rechew it and swallow, or spit it out. Luckily, this rare condition is fully treatable.


1. Regurgitation Occurs Automatically

In rumination syndrome, regurgitation is not intentional. It typically occurs within ten minutes to one hour of eating, at which point the previously swallowed food comes back up into the mouth. Individuals with rumination syndrome typically report that food comes up in the same state it went down; that is, undigested and without any vomit-like taste.
