Peptic Ulcer

This is a sore that forms in the lining of your digestive tract. It develops when stomach acid eats through the mucus layer that protects the walls of your digestive tract. A peptic ulcer can form in your stomach. It can also form in your esophagus, or in the upper part of your small intestine.
