Acidity Gives You Heartburn! Burrrrrrrrp!!! Oh, this is one embarrassing sound that escapes your mouth. While burping in some cultures is considered as a compliment for a good sumptuous meal that one has, but not everywhere. And if it becomes frequent and with foul smell, then there is a problem. The problem is coined as Acidity or Indigestion or Heartburn, where it is an uncomfortable burning sensation triggered by the stomach leading back up to the Esophagus, the Food Pipe. The sensation is like a fire travelling from your chest to your throat. Prolonged heartburn, if not treated, may lead to a disease called GERD (Gastroesophageal Reflux Disease) and in rare cases it might lead to cancer.
