Heartburn, or acid reflux, occurs when stomach acid flows backward into the esophagus, the tube that carries food from your mouth to your stomach. This can happen after eating spicy foods, lying down too soon after a meal, or wearing tight-fitting clothing.

Heartburn symptoms include a burning sensation in the chest, trouble swallowing, and a sour taste in the mouth.

Treatment for heartburn typically involves antacids, which neutralize stomach acid. Some people may also need prescription medications to control their symptoms.

Heartburn is a common condition that affects millions of people worldwide. While it can be uncomfortable, it is usually not a serious condition.

However, heartburn that occurs frequently or is left untreated can lead to more serious problems, such as gastroesophageal reflux disease (GERD).

GERD is a chronic condition that can damage the esophagus and lead to other health complications. If you experience heartburn frequently, talk to your doctor to find out if you have GERD.
