Heartburn is the common name for esophagitis, a burning sensation of "indigestion" localized centrally in the upper abdomen or lower chest. It is frequently worse after large meals or on lying flat, especially with hiatus hernia. Acid stomach contents irritate the esophageal epithelium and may lead to ulcer; relief is with antacids. Heartburn is also loosely applied to other pain in the same situation.
