General Information

Gastroesophageal reflux, also called "acid reflux," occurs when the stomach contents back up into the esophagus and/or mouth. Most episodes are brief and do not cause bothersome symptoms or complications.

By contrast, people with gastroesophageal reflux disease (GERD) experience bothersome symptoms or damage to the esophagus as a result of acid reflux.

Symptoms of GERD can include:

  • Heartburn - This typically feels like a burning sensation in the center of the chest, which sometimes spreads to the throat. It most often happens after a large meal.
  • Regurgitation - This is when stomach contents (acid mixed with bits of undigested food) flow back into your mouth or throat.
  • Difficulty or pain with swallowing
  • Persistent sore throat or cough

Over time, GERD can lead to complications. These include problems related to esophageal damage, as well as other issues.
