What is the best way to cure heartburn?

Heartburn is caused by stomach acid moving up out of the stomach into the lower part of the esophagus. Living a healthy lifestyle may be one of the best things you can do to tame the heartburn of gastroesophageal reflux disease (GERD). This includes maintaining a healthy body weight; not smoking; getting 30 minutes daily of moderate-to-vigorous physical activity; limiting coffee, tea, or soda to no more than 2 cups per day; and eating a healthy diet. Each one of these factors may prevent the inappropriate relaxation of the sphincter muscle between the stomach and the esophagus, helping to keep acid from refluxing up and causing heartburn.
