"Heartburn is a condition in which you feel burning behind your chest and it can be a symptom of reflux," says Dr. Shah. "Reflux is the medical term given to the stomach contents coming up into your esophagus. Heartburn is one of the common symptoms."

Is there a difference between acid reflux and heartburn?

Are they the same thing? Acid reflux occurs when stomach acid backs up into the esophagus irritating the tissue. Heartburn, or acid indigestion, is a symptom of acid reflux, so named because the esophagus lies just behind the heart, and that is where the burning sensation is felt.

Can you have heartburn without acid reflux?

But is it possible to suffer from reflux and not know it? Laryngopharyngeal reflux (LPR) or “silent reflux” is a condition in which acid from the stomach travels up the esophagus and gets to the throat. This type of acid reflux typically does not produce heartburn or indigestion like GERD.
