Peptic Ulcer Disease — NEET PG Notes
Master peptic ulcer disease as one clean story: acid-pepsin injury versus mucosal defence, with H. pylori as the central driver. Built for NEET-PG recall and practical clinical reasoning.
Why This Guide
PUD becomes easy when the whole chapter is arranged around one clinical logic: too much acid at the wrong place causes duodenal ulcer, while weak mucosal defence explains gastric ulcer — even in low-acid states.
This note connects H. pylori, Type A and Type B gastritis, gastric versus duodenal ulcer, diagnostic test selection, eradication therapy, emergency complications, PPI adverse effects, rapid revision points, and clinical MCQs into one exam-friendly framework.
What You’ll Learn
- The core PUD framework — acid-pepsin injury versus mucosal defence, with H. pylori as the key driver.
- H. pylori logic — urease, ammonia shield, hypergastrinemia, hyperchlorhydria, MALToma and gastric cancer links.
- Type A vs Type B gastritis — autoimmune fundus versus H. pylori antrum, with pernicious anemia and cancer risk.
- Gastric ulcer vs duodenal ulcer — food-pain pattern, weight change, acid status, blood group, cancer risk and bleeding artery.
- Diagnosis made simple — UBT for H. pylori, upper GI endoscopy for ulcer crater, and how PPIs, antibiotics and bismuth cause false-negative tests.
- Treatment frameworks — CAP triple therapy, bismuth quadruple therapy, hybrid therapy, LOAD regimen and bismuth counselling pearls.
- Complications you must never miss — bleeding, perforation, penetration, gastric outlet obstruction, gastrocolic fistula and malignancy.
- Rapid revision + MCQs — high-yield checklist and clinical reasoning questions for NEET-PG style preparation.
