Peptic ulcer disease
Peptic ulcer disease involves open sores that develop on the inside lining of the stomach and the upper portion of the small intestine. It is most commonly caused by bacterial infection or long-term use of anti-inflammatory medications.
Overview
Peptic ulcer disease involves open sores that develop on the inside lining of the stomach and the upper portion of the small intestine. It is most commonly caused by bacterial infection or long-term use of anti-inflammatory medications.
Understand this condition
The stomach and small intestine are coated with a thick mucus layer to protect against acid. When this protective layer breaks down, stomach acid eats away at the organ tissue. This process creates an open sore, known as an ulcer, in the digestive lining.
Why it happens
Most ulcers result from a bacterial infection or long-term medication use that thins the protective mucus. Without this barrier, acidic digestive juices irritate the underlying tissue and cause inflammation. If left untreated, the sore can deepen and potentially cause bleeding or a perforation.
