What Is Heartburn
Heartburn is not a disease and also it has nothing to do with heart disease. It is an irritation or burning sensation occurs in upper esophagus, the part which connects throat and stomach. This irritation is basically caused by stomach acid which leads to discomfort in upper belly or below breastbone or sternum. The pain of heartburn or acid reflux may remain in the lower chest but if it reaches near larynx it may cause coughing. Heartburn or acid reflux if persist for few time then it is ok, but if stays for a long time then it may lead to GERD (Gastroesophageal reflux Disease).
