Clinical Correlates (GERD, Peptic Ulcers, Hepatitis)
Start with the big picture
GERD develops when an ineffective lower esophageal sphincter allows acidic contents to injure the distal esophagus. The lesson links its risk factors and symptoms with complications such as erosive esophagitis, strictures, and Barrett metaplasia. PUD occurs when acid-pepsin injury exceeds mucosal defenses; Helicobacter pylori and NSAID use are key causes. Differences in meal-related pain, ulcer location, and alarm features help distinguish important clinical patterns. The viral hepatitis overview introduces acute liver findings and compares transmission and chronicity across hepatitis A, B, D, and other covered forms. Together, these topics show how pathophysiology, clinical presentation, and complications inform evaluation.
What you'll learn

- Identify common GERD symptoms, complications, and histologic features.
- Compare major causes and pain patterns of gastric and duodenal ulcers.
- Recognize ulcer alarm features and complications associated with location.
- Summarize distinguishing features of acute viral hepatitis types.
