Which statement best describes GERD compared with peptic ulcer disease?

• A. GERD results from lower esophageal sphincter incompetence causing reflux; peptic ulcers are mucosal erosions in the stomach/duodenum due to H. pylori or NSAIDs
• B. GERD is due to increased acid production; PUD is due to lax motility
• C. GERD only occurs in the elderly; PUD only in children
• D. GERD involves duodenal ulcers; PUD involves esophageal ulcers

Answer: (A)

The main idea is that GERD and peptic ulcer disease differ in both where the injury occurs and why it happens. GERD happens when the lower esophageal sphincter isn’t doing its job, allowing stomach acid to reflux up into the esophagus and irritate it. Peptic ulcer disease is about actual mucosal erosions in the stomach or the first part of the small intestine (the duodenum), typically due to a mucosal defense break in combination with factors like Helicobacter pylori infection or NSAID use. That’s why the best description is the one that pairs reflux from LES incompetence with esophageal irritation for GERD, and mucosal erosions in the stomach or duodenum due to H. pylori or NSAIDs for PUD. The other statements mix up mechanisms or locations (for example, GERD is not defined by increased acid production, PUD isn’t caused by lax motility, these conditions aren’t restricted to specific ages, and ulcers are not primarily in the esophagus for PUD nor limited to the duodenum for GERD).
