What causes heartburn?
Heartburn typically occurs after eating a large meal or drinking a lot of alcohol. Some people get heartburn when they bend over or lie down. The frequency of stomach acid reflux varies from one person to another. For most people, it happens very
rarely. But weekly or daily incidents of heartburn or acid regurgitation may occur.
Heartburn is the most common symptom of a condition called gastroesophageal reflux or acid reflux. A sphincter (specialized muscle), known as the lower esophageal sphincter (LES), is located at the end of the esophagus and opens during swallowing to allow food to pass into the stomach. The LES muscle then closes quickly to prevent the return (reflux) of food and stomach juices back into the esophagus.
However, the LES muscle does not always work perfectly. Gastroesophageal reflux occurs when the LES muscle either relaxes inappropriately or is weak. This allows stomach juices to back up, or reflux, into the esophagus, creating heartburn. When the acid contents from the stomach regularly back up into the esophagus, a chronic condition called gastroesophageal reflux disease, or GERD, occurs. Heartburn is sometimes called acid indigestion and usually occurs after meals. In addition to heartburn, symptoms of acid reflux may include persistent sore throat, hoarseness, chronic cough, asthma, heart-like chest pain and a feeling of a lump in the throat.
