Gastric distension
Gastric distention is the enlargement of the stomach, and can be due to a number of causes.[citation needed]
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:
- binge eating associated with bulimia nervosa[3]
- tumors causing obstruction[4]
- diabetic neuropathy
- scarring due to pyloric gastritis[5]
- delayed gastric emptying[6]
To identify the cause of gastric distention, an upper endoscopy or barium upper GI imaging should be done.[7]
