Heartburn is very common -- and very unpleasant. It's triggered when stomach acid backs up into the esophagus. It can make you feel as though someone has lit a small bonfire in your chest, and it's burning its way up to your neck.

You're probably well aware that medications can help calm the burn, but natural heartburn remedies and lifestyle changes may be another way to get relief.

One commonly used "natural" heartburn remedy is calcium. It's also the active ingredient in many over-the-counter antacids.

If you find yourself popping antacids like candy and you're having heartburn more than a couple of times a week, or if you are using antacids for longer than two weeks, it's time to see the doctor. You may have a condition called GERD -- gastroesophageal reflux disease or another problem like peptic ulcer disease. Frequent heartburn can lead to long-term problems. It can cause inflammation and strictures in your esophagus. In rare cases, it may even lead to cancer. But stopping the acid reflux can help prevent complications in the future.

Here is a rundown of some other commonly used home remedies for heartburn, and the evidence for their effectiveness.
