Question

why are the contents of gastric juice so hostile to the exposed duodenal wall?

Answer 1

@babsarica Most common cause of a duodenal ulcer is an excessive secretion (Hypersecretion) of gastric juice. Other factors, such as certain drugs, nicotine or stress can encourage the formation of ulcers in the duodenum.
