There are many digestive problems involving the esophagus (e.g. achalasia, squamous cell carcinoma of the esophagus, etc), but one of the most common esophageal diseases are heartburn or reflux disease also known as gastroesophageal reflux disease or GERD. GERD is characterized by the backflow of the stomach acids to the distal end of the esophagus causing damage and erosion.
