Gastroesophageal reflux disease (GERD) occurs when stomach acid repeatedly flows back into the tube connecting your mouth and stomach (esophagus). This backwash (acid reflux) can irritate the lining of your esophagus.

Many people experience acid reflux from time to time. However, when acid reflux happens repeatedly over time, it can cause GERD.

Most people are able to manage the discomfort of GERD with lifestyle changes and medications. And though it's uncommon, some may need surgery to ease symptoms.

Symptoms
