Burning is that painful sensation that is commonly experienced with GERD, heartburn and indigestion. Acid is the cause, and what makes the difference is how often or where this painful burn is felt.
GERD, or gastroesophageal reflux disease, is a more serious form of gastroesophageal reflux, which is common.
Persistent reflux that occurs more than twice a week is considered GERD, and it can eventually lead to more serious health problems. You can have GERD without having heartburn, and other symptoms may could include:
Chronic GERD, that is left untreated, can cause serious throat problems. Stomach acid can damage its lining and cause bleeding or ulcers. Also, scaring from tissue damage can narrow your esophagus making it difficult to swallow.
Heartburn is a painful burning feeling in your chest or throat. It happens when stomach acid backs up into your esophagus, the tube that carries food from your mouth to your stomach.
Some people also use the term indigestion to describe the symptom of heartburn.
If you have persistent indigestion that is not related to any of these factors, it may be caused by a problem in the muscular squeezing action of the stomach (motility function).
