Burning stomach acid happens when acidic digestive fluids flow backward into the esophagus, irritating its lining. This condition is medically known as acid reflux or gastroesophageal reflux (GER).
The lower esophageal sphincter (LES), a ring of muscle between the stomach and esophagus, usually closes tightly after food passes through. If the LES relaxes abnormally or weakens, stomach acid can flow back up, causing a burning sensation. Occasional acid reflux is common, but frequent episodes may indicate gastroesophageal reflux disease (GERD).
Common triggers include:
According to the American College of Gastroenterology, obesity increases the risk of GERD due to increased abdominal pressure.
Symptoms vary but often include:
