We’ve spoken about gastritis. Peptic ulcer disease is a related but different kettle of fish. Now ulcers, you can think of it as a cut or a sore in the lining of the stomach. All right, so imagine if you had a cut and now you’re sprinkling that cut or bathing that cut with acid. Okay. Ouch. That would hurt. All right, so when patients have an ulcer, especially in the stomach, then it’s being coded with acid on a fairly frequent basis. Now this acid serves as an irritant and it may also prevent the ulcer from healing. It can cause an extension of an ulcer. And ulcer symptoms are somewhat different then gastritis type symptoms.
