Dysphagia
It is commonly known as difficult or painful swallowing, and it is a common symptom in people who suffer from sustained acid reflux. What’s more, there’s a complication of gastroesophageal reflux disease called Barrett’s esophagus. It is a severe condition in which the esophagus undergoes adaptive changes to the sustained injury from the stomach acid. The esophagus slowly becomes a thick and hard structure, and it may even end up in esophageal cancer.
