Heartburn is a common condition that may affect anyone. It usually happens when the lower esophageal sphincter or LES is not working well. The LES is a muscular valve found at the end of the esophagus that works to keep food as well as liquid and other digestive uses in the stomach where it belongs. But when the LES becomes weak or doesn’t work right, stomach contents along with the digestive juices tend to move back into the esophagus causing what is known as heart burn.
