GERD, or gastroesophageal reflux disease, is a common condition caused by stomach acid that flows from the stomach back into the esophagus. Also known as acid reflux, GERD can cause irritation to the esophageal lining.
A diagnosis of GERD is pronounced when patients who suffer from mild acid reflux at least twice weekly or moderate acid reflux at least once weekly. Roughly 46% of Americans are diagnosed with GERD, experiencing symptoms such as:
- Heartburn, especially after eating at night
- Difficulty swallowing
- Chest pain
- The sensation of a lump in the throat
- Chronic cough
- Sleep disturbances2
