What is heartburn?

Heartburn is known for the burning sensation that often extends from the bottom of the breastbone to the lower throat. Women who have never experienced it before could have their first contact with the nasty burning sensation during pregnancy. Almost everyone has experienced heartburn, where about 25 million American adults suffer daily from it. Although there are plenty of over the counter and prescribed medications one can use for treating this problem, they do have their downsides such as unwanted side effects, which may lead to other health issues for a person suffering from acid reflux.
