Indigestion and heartburn can cause excessive belching. Heartburn can stem from acid reflux, be the symptom of a peptic ulcer, or a sign that last night's spicy meal did not agree with your stomach lining.

Conditions that may cause belching include: gastroesophageal reflux disease (GERD): a disorder that causes acid from the stomach to flow upward into the esophagus, or food pipe.
