Which class of medications should be avoided due to risk of stomach ulcers after bariatric surgery?

• A. Antibiotics
• B. NSAIDs
• C. Antihistamines
• D. Beta-blockers

Answer: (B)

NSAIDs increase ulcer risk because they block enzymes that make protective prostaglandins in the stomach. Prostaglandins help maintain the stomach’s protective mucus, bicarbonate, and blood flow; when their production is reduced, the lining becomes more vulnerable to acid and can develop gastritis or ulcers. After bariatric surgery, the stomach and surgical connections are especially delicate, so NSAIDs can more easily cause ulcers at the staple line or surrounding tissue and impede healing. That’s why avoiding this class is advised postoperatively. For pain, safer options like acetaminophen are typically used, and any anti-inflammatory needs should be discussed with a clinician. The other medications mentioned don’t carry the same ulcer risk in this context.
