👉 A peptic ulcer, also known as a peptic ulcer disease (PUD), is a type of digestive tract inflammation that occurs in the upper part of the stomach. It can cause severe pain and discomfort when it's present, particularly in the early stages, but can progress to more serious conditions like bleeding or perforation if left untreated. The term "peptizes" refers to the breakdown of peptic ulcers into smaller pieces, which is a process that occurs in the digestive system.
