How does gastroesophageal reflux in infants occur?

1, anti-reflux structure

and function impairment such

as delayed gastric emptying, increased intra-abdominal pressure, gastric dilation, etc., will damage the structure of the lower esophageal sphincter, making it difficult to block gastric contents reflux into the esophagus, resulting in gastroesophageal reflux.

2, food clearance decreased Esophagus

can clear substances through its own peristaltic and saliva, if esophageal motility slowed down or saliva secretion decreased, resulting in decreased esophageal clearance, but also easy to cause gastroesophageal reflux.

3, esophageal mucosal defense reduced such

as eating rough, hard or spicy food, will cause irritation and damage to the esophageal mucosa, so that its defense ability decreased, and then cause gastroesophageal reflux.
