A peptic ulcer is a wound that forms on the lining of the stomach, small intestine, or esophagus, which is the swallowing tube. This condition is often caused by an infection with the bacterium Helicobacter pylori or long-term use of pain relievers like ibuprofen and aspirin. Symptoms of a peptic ulcer can include burning stomach pain, bloating, heartburn, and nausea. If left untreated, peptic ulcers can lead to serious complications such as bleeding, holes in the stomach or intestine, and blockages. Treatment typically involves antibiotics to clear the infection, medications to reduce stomach acid, and lifestyle changes to promote healing and prevent recurrence.
