Esempio
Disorders of the esophagus, such as gastroesophageal reflux disease (GERD) or esophageal cancer, can cause symptoms like heartburn, difficulty swallowing, or chest pain.
The lower esophageal sphincter (LES) is a ring of muscle at the bottom of the esophagus that opens to let food into the stomach and closes to prevent stomach acid from coming back up into the esophagus.
A blockage or narrowing of the esophagus, called esophageal stricture, can make it difficult or painful to swallow food or liquids.
