Gastric distention is the enlargement of the stomach, and can be due to a number of causes.

Physiologic (normal) gastric distension occurs when eating. Distension of the upper stomach stimulates the secretion of stomach acid, while distension of the lower stomach stimulates gastrin secretion.[1] Distension of the stomach also stimulates the secretion of ghrelin.[2]

Other causes include:

To identify the cause of gastric distention, an upper endoscopy or barium upper GI imaging should be done.[7]
