Summary

This lesson introduces peptic ulcer disease (PUD), explains where ulcers occur, and describes common symptoms and warning signs.

A peptic ulcer is a break in the lining of the digestive tract that extends through the muscularis mucosae. Ulcers most often occur in the stomach or the first part of the small intestine, and less often in the lower esophagus.
