Acid Reflux Symptoms


Heartburn, also called acid indigestion, is one of the most common symptoms of acid reflux. It refers to a painful, burning sensation or sense of discomfort that occurs in the middle of your abdomen and rises up through your chest and/or throat. Despite its name, heartburn does not affect your heart.


Another common acid reflux symptom, regurgitation describes the sensation of acid rising up into your throat or mouth. Regurgitation may produce a sour or bitter taste, and can sometimes cause burping and vomiting.

When symptoms occur

Acid reflux symptoms most often occur:

  • after eating a heavy meal
  • when bending over, or lifting a heavy object
  • when lying down, especially on your back
  • at night
