What Is Regurgitation, and Why Does It Happen

Regurgitation happens when a mixture of gastric juices, and sometimes undigested food, rises back up the esophagus and into the mouth. In adults, involuntary regurgitation is a common symptom of acid reflux and GERD. It may also be a symptom of a rare condition called rumination disorder. In babies, regurgitation is normal within the first year of life. This article will explore the common causes, diagnosis, and treatment for involuntary regurgitation in both adults and babies.
