What Causes Acid Reflux?

Acid reflux may be triggered for a number of reasons, including hiatal hernia, pregnancy, smoking, or eating certain foods.
July 08, 2019

Acid reflux happens when the lower esophageal sphincter (LES), a ring of muscle between the esophagus and stomach, does not operate correctly. The job of the lower esophageal sphincter is to relax to let food pass through to the stomach, then close to prevent stomach acid from creeping into the esophagus. When the tissue is weakened or malfunctions in some way, stomach acid may splash back into the esophagus and cause inflammation that we often refer to as “heartburn.”

What Is GERD?

GERD, or Gastroesophageal Reflux Disease, is a common digestive disorder characterized by the chronic passage of stomach acid into the esophagus.
June 24, 2019

In the medical world, GERD is an acronym for Gastroesophageal reflux disease. It’s a digestive disorder related to the lower esophageal sphincter (LES), a ring of muscle between the esophagus and stomach.

Normally, the LES relaxes and opens its ring to allow food to enter the stomach, then closes back up. With GERD, the LES is weakened or moves in an abnormal way that leaves the passageway open for stomach acid to splash back up into the esophagus. Your stomach is equipped to handle the stomach acid, but over time, that same stomach acid could be erosive to your esophagus. The inflammation caused by stomach acid is referred to as acid reflux, or often felt as heartburn.
