Upper GI hemorrhage is most commonly due to which condition?

• A. Diverticulosis
• B. Hemorrhoids
• C. Peptic ulcer disease from NSAIDs or alcohol
• D. Esophageal varices in all cases

Answer: (C)

The key idea here is that the most common source of upper gastrointestinal bleeding in adults is peptic ulcer disease, typically from ulcers in the stomach or duodenum caused by NSAID use or alcohol. NSAIDs disrupt protective prostaglandins in the gastric mucosa, increasing susceptibility to ulceration and bleeding; alcohol can also damage the mucosa and promote ulcer formation. While esophageal varices can cause serious upper GI bleeding, they occur mainly in people with portal hypertension (such as cirrhosis) and are not the most frequent cause overall. Diverticulosis and hemorrhoids are lower GI sources and usually present with bleeding from the colon or rectum, not the upper GI tract. So peptic ulcers from NSAID or alcohol exposure best explains why upper GI bleeding is most commonly seen.
