K28: Gastrojejunal ulcer

Gastrojejunal ulcers fall under a group of digestive conditions that occur when sores or ulcers form in the lining of the stomach and the upper part of the small intestine, specifically the jejunum. This often results from an imbalance between digestive fluids in the stomach and duodenum, and the body's ability to protect the gastrointestinal lining. A common cause includes infection with bacteria called Helicobacter pylori (H. pylori) or long-term use of drugs like nonsteroidal anti-inflammatory drugs (NSAIDs). Symptoms typically include a burning or gnawing pain in the middle or upper stomach between meals or at night, bloating, heartburn, indigestion, nausea, or weight loss. Left untreated, gastrojejunal ulcers can lead to serious complications including bleeding, perforation, or obstruction of the digestive system.
