Heart burn

 

Heartburn is a burning sensation or discomfort in the chest and throat that results from stomach acid backing up into the esophagus. This happens when the lower esophageal sphincter (LES), a ring of muscle that separates the stomach from the esophagus, doesn't close properly or relaxes at the wrong times. Common symptoms of heartburn include a burning feeling in the chest, a sour or bitter taste in the back of the throat, and sometimes, regurgitation of stomach acid into the mouth.

Heartburn is often triggered by certain foods, lifestyle factors, or underlying conditions like gastroesophageal reflux disease (GERD). It's a common and usually temporary condition, but chronic or severe heartburn can lead to complications and should be evaluated by a healthcare professional. Treatment options range from lifestyle changes and dietary modifications to medications and, in some cases, surgery.
