Go behind the scenes to see what causes heartburn.

You might refer to it as that frustrating pain or discomfort that may occur after you eat, but it’s more complex than that.

What is heartburn?

Heartburn occurs when acid from the stomach moves back into the esophagus, thus causing pain and discomfort in your chest, and maybe even a bitter taste in your mouth.

Why is it painful?

The fluids produced by your stomach to help your body digest food contain a powerful acid called hydrochloric acid - something your stomach is naturally protected from, but your esophagus is less so. Therefore if the hydrochloric acid moves back or “refluxes” into your esophagus, the more sensitive lining of the esophagus can become irritated, thus resulting in heartburn pain.

See heartburn in action.

And if you have heartburn symptoms occurring 2 or more days a week, that’s classified as frequent heartburn. So it’s the same discomfort of heartburn, just more frequent.
