Common causes and involved organs
Pain in the upper abdomen may originate from the stomach, oesophagus, pancreas, gallbladder and bile ducts, liver, or the upper intestine and abdominal wall. Frequent causes include reflux and gastritis, peptic ulcer disease, gallstone-related biliary colic, pancreatitis, and musculoskeletal pain. Sometimes cardiac pain near the lower chest can be perceived as upper abdominal discomfort. Each source tends to have typical accompanying features that help clinicians differentiate between them.
