2. Key Concepts to Study
Gastrointestinal pathologies:
Pathophysiology of GERD
Gastroesophageal reflux disease (GERD) occurs when the
lower esophageal sphincter (LES) becomes weakened or
relaxes inappropriately, allowing gastric acid to reflux
into the esophagus. Chronic exposure to acid causes
mucosal inflammation, irritation, and possible erosion.
Signs and Symptoms of GERD

, lOMoAR cPSD| 66470069
Common symptoms include heartburn, regurgitation,
chest pain, dysphagia, chronic cough, and hoarseness,
particularly after meals or when lying down.
Pharmacologic Management of GERD
Treatment includes proton pump inhibitors (PPIs) such as
omeprazole, H2 receptor antagonists like famotidine, and
antacids for symptomatic relief. Prokinetic agents may be
used in selected cases.
Risk Factors for Esophageal Stricture
Chronic GERD, prolonged acid exposure, esophageal
injury, radiation therapy, or ingestion of caustic
substances can lead to fibrosis and narrowing of the
esophagus.
