Acid reflux, also known as gastroesophageal reflux disease (GERD), is a condition in which stomach acid leaks back up into the esophagus, causing heartburn and other uncomfortable symptoms.

While most people experience occasional heartburn, people with GERD suffer from heartburn and other symptoms more often, and it can be severe enough to interfere with daily life.

There are a number of things that can contribute to GERD, including diet, lifestyle, and medical conditions. Knowing what triggers your symptoms can help you avoid them and find relief.
