What causes Acid Reflux?

Acid reflux is caused by weakness or relaxation of the lower esophageal sphincter (valve). Normally this valve closes tightly after food enters your stomach. If it relaxes when it shouldn’t, your stomach contents rise back up into the esophagus.Acid backwash then flows back up through your esophagus into your throat and mouth, giving you a sour taste.

Acid reflux happens to nearly everyone at some point in life. Having acid reflux and heartburn now and then is totally normal. But, if you have acid reflux/heartburn more than twice a week over a period of several weeks, constantly take heartburn medications and antacids yet your symptoms keep returning, you may have developed GERD. Your GERD should be treated by your healthcare provider. Not just to relieve your symptoms, but because GERD can lead to more serious problems.
