Gastroesophageal reflux disease (GERD) 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 esophagus.
Many people experience acid reflux from time to time. GERD 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 GERD with lifestyle changes and over-the-counter medications. But some people with GERD may need stronger medications or surgery to ease symptoms.
Common signs and symptoms of GERD include:
-A burning sensation in your chest (heartburn), usually after eating, which might be worse at night.
-Regurgitation of food or sour liquid.
-Sensation of a lump in your throat.
If you have nighttime acid reflux, you might also experience:
-New or worsening asthma.
