Duodenal ulcer is the diagnosis for a patient who experiences chronic intermittent pain in the epigastric area when the stomach is empty and in the middle of the night.
A duodenal ulcer is a peptic ulcer that develops in the first part of the small intestine. It occurs in the lower part of the esophagus. Few symptoms of duodenal ulcer are a dull or burning pain in the belly. The main cause of this ulcer is bacterial infection. The bacteria causes the lining of the stomach to become inflamed and an ulcer can form. Few medications such as ibuprofen may also cause ulcer.
The wound generally heals on its own but if the ulcer is deep it can cause serious pain or bleeding.
