Gastroesophageal reflux disease (GORD) occurs when stomach acid frequently flows back into the tube connecting your mouth and stomach (esophagus). This backwash (acid reflux) can irritate the lining of your oesophagus.
Many people experience acid reflux from time to time. GORD is mild acid reflux that occurs at least twice a week, or moderate to severe acid reflux that occurs at least once a week.
Most people can manage the discomfort of GORD with lifestyle changes and over-the-counter medications. But some people with GORD may need stronger medications or surgery to ease symptoms.
