Gastroesophageal reflux in infants

Alternative names:

chalasia; GE reflux; reflux

Definition:

The movement of stomach contents up the esophagus in a direction against normal peristalsis. Adults may develop gastroesophageal reflux disease.

In infants, a small amount of reflux is normal. Persistent reflux with frequent vomiting, and subsequent irritation of the esophagus is indicated by unrelenting crying and discomfort. Reflux that causes breathing difficulty is considered abnormal.
