Heartburn is a burning pain in your chest, just behind your breastbone. The pain is often worse after eating, in the evening, or when lying down or bending over.
Common symptoms
Causes
A burning pain in the chest that usually occurs after eating and may occur at night
Pain that worsens when lying down or bending over
A bitter or acidic taste in the mouth
Heartburn occurs when stomach acid backs up into the tube that carries food from your mouth to your stomach (esophagus).
Typically, when food is swallowed, a band of muscle around the bottom of the esophagus (lower esophageal sphincter) relaxes to allow food and liquid to flow down into the stomach. Then the muscle tightens again.
If the lower esophageal sphincter isn't working as it should, stomach acid can flow back up into the esophagus (acid reflux) and cause heartburn. The acid backup may be worse when you're bent over or lying down.
