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. 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.
