oa SA Pharmacist's Assistant - Heartburn : gut health
Heartburn occurs when the valve between the stomach and oesophagus (the tube that carries food from the mouth to the stomach), is unable to prevent the gastric contents, particularly acid, from passing back into the oesophagus. The stomach acid can irritate the oesophagus and cause heartburn. The symptoms of heartburn are typically described as a painful or burning sensation in the upper abdomen or chest, which sometimes radiates to the back. Acid reflux may also come up into the throat or mouth, leaving a bitter or sour taste in the mouth. Heartburn usually lasts for a few minutes, but may persist for several hours.
