gastroesophageal reflux
Also written as: GER — gastroesophageal reflux
The backward flow of stomach contents into the esophagus, common in infants and may require treatment if causing symptoms.
Full Definition
Gastroesophageal reflux (GER) is the physiologic passage of gastric contents into the esophagus, which is common and usually benign in healthy infants. However, when reflux causes troublesome symptoms or complications, it becomes gastroesophageal reflux disease (GERD). In infants, symptoms may include frequent spitting up, irritability during or after feeding, arching of the back, and poor weight gain. Most cases resolve spontaneously as the lower esophageal sphincter matures. Treatment ranges from conservative measures like positioning and feeding modifications to medications such as proton pump inhibitors in severe cases. Distinction between physiologic GER and pathologic GERD is crucial for appropriate management.
Usage
Usage note: Distinguish from GERD (gastroesophageal reflux disease). Note British spelling uses 'oesophageal'.
