What is Acid Reflux?

Acid reflux, or heartburn, happens as a result of a failed lower esophageal sphincter (LES). The LES is located between the esophagus and the stomach. When working correctly, the LES stops acid from moving up from the stomach into the esophagus. A weak LES allows acid to flow upward, causing heartburn.
