Do you want to have heartburn no more, but do not know what kind of treatment to take? If you have occasional heartburn, then you should consider eating smaller meals and standing or sitting up after a meal. Usually heartburn will be caused by lying down after a meal, increasing the risk that stomach acid will back up into the esophagus. Another home treatment includes taking an antacid, which neutralizes the stomach acid in the esophagus, thus lowering the burning sensation. Occasional heartburn can be a pain, but it tends to go away on its own or with home treatments.
