Regurgitation can arise from 3 documented medical conditions. Understanding the clinical context helps identify urgent causes early.
GERD (Acid Reflux)
Gastroesophageal reflux disease (GERD) is a chronic condition where stomach acid flows back into the esophagus, causing heartburn, regurgitation, and chest discomfort. Long-term untreated GERD can lead to esophageal damage.
Esophageal Cancer
Esophageal cancer presents with progressive difficulty swallowing and weight loss. The two main types are squamous cell carcinoma (related to smoking and alcohol) and adenocarcinoma (related to GERD and Barrett's esophagus).
Achalasia
Achalasia is a motility disorder where the lower esophageal sphincter fails to relax and esophageal peristalsis is absent, causing progressive dysphagia to both solids and liquids, regurgitation, and weight loss. Treatment includes pneumatic dilation or surgical myotomy.
