<h3>What does it mean if you have constant heartburn?</h3>
If you have frequent or constant heartburn (more than twice a week or heartburn every day), you may have gastroesophageal reflux disease (GERD). GERD is a digestive disorder that affects the lower esophageal sphincter (LES), a muscle that connects the esophagus and the stomach.
Heartburn can have causes that aren't due to underlying disease. Examples include spicy food, alcohol, overeating, or tight clothing. An occasional bout of heartburn usually means that the foods the person ate produced too much acid in the stomach.
