Esophagitis generally does not cause coughing, as coughing is a symptom of respiratory diseases. Esophagitis mostly causes symptoms of the digestive system, such as heartburn, particularly when eating food, accompanied by painful swallowing, and pain behind the sternum. Severe esophagitis can lead to the narrowing of the esophageal lumen, difficulty swallowing, and may also present with vomiting. Esophagitis can also cause bleeding; bleeding of the mucous membranes can lead to vomiting blood or black stools. Recurrent esophagitis causes a decrease in appetite and impairs absorptive functions, leading to weight loss.
