What is Acid Reflux Disease?
Acid reflux disease is a chronic condition in which stomach acid washes back up onto the esophagus, causing severe discomfort. Stomach acid burns the esophagus lining due to a relaxed lower esophageal sphincter (LES). The LES acts as a valve between your stomach and the esophagus. The valve is designed to open and allow food into the stomach, and then close, protecting the esophagus from acids. However, if the LES is not closing properly, acid rushes or refluxes upward, coating the esophagus, and causes a burning sensation.
Remember that it’s normal to suffer from acid reflux (heartburn) every once and awhile. It’s only acid reflux disease when it’s a chronic condition, happening frequently and for long periods of time. If you are unsure, don’t hesitate to see your doctor. One more thing to keep in mind is that heartburn has nothing to do with your heart. It just feels that way at times because the esophagus is located behind the heart.
