Heartburn typically refers to pain in the chest due to stomach acid flowing back up into the esophagus causing a burning sensation. Since stomach acid is causing the burning sensation, heartburn is commonly associated with hyperacidity. Heartburn is a symptom of GERD. Risk factors include those that increase the production of acid in the stomach, as well as structural problems that allow acid reflux into the esophagus.
What Causes Heartburn?
Heartburn occurs when stomach acid backs up into the tube that carries food from your mouth to your stomach. Normally when you swallow, a band of muscle around the bottom of your esophagus relaxes to allow food and liquid to flow down into your stomach. Then the muscle tightens again. If the lower esophageal sphincter relaxes abnormally or weakens, stomach acid can flow back up into your esophagus and cause heartburn.
