Gastroesophageal reflux in infants.

Gastroesophageal reflux (GER) occurs when stomach contents reflux, or back up, into the esophagus during or after a meal. The esophagus is the tube that connects the mouth to the stomach. A ring of muscle at the bottom of the esophagus opens and closes to allow food to enter the stomach. This ring of muscle is called the lower esophageal sphincter (LES). The LES normally opens to release gas after meals. With infants, when the LES opens, stomach contents often reflux into the esophagus and out the mouth, resulting in regurgita­ tion, or spitting up, and vomiting. GER can also occur when babies cough, cry, or strain.
