What is acid reflux disease?
When the muscle at the entrance of the stomach opens too often or don’t close after food enters the stomach, acid produced by the stomach moves up to the esophagus. This is called acid reflux. If this happens more than twice a week, you have acid reflux disease.
Common symptoms include:
- Bloody stools
The common cause of the disease is hiatal hernia. When it occurs, the lower esophageal sphincter (LES) and the upper part of the stomach move above the diaphragm (a muscle that separates your chest and stomach). When functioning normally, the diaphragm prevents acid from traveling out of the stomach. But once you experience a hiatal hernia, acid moves up to the esophagus and you feel symptoms of the disease.
