About Your Care and Condition
Acid reflux, also known as gastroesophageal reflux disease, or GERD, is a digestive disorder that occurs when your stomach acid flows back into your esophagus. If you are experiencing heartburn or acid indigestion, you may have GERD.
GERD is the result of the progression of occasional heartburn to a chronic condition of more than twice weekly. It is caused by a faulty valve between the esophagus and stomach. Without tight closure, stomach acid backs up into the esophagus. This can progress to a serious condition called Barrett's esophagus and a greater risk of esophageal cancer.
