In many cases, these changes cause a personâs organs to stop working. 1  Some of the signs that organs are affected include: 2  Heart â low blood pressure, fast pulse. 3  Lungs â low oxygen level, problems breathing. 4  Kidneys â making very little urine. 5  Brain â confusion, coma.
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.
Swallowing air and belching are natural occurrences that result from eating or drinking too quickly. Chewing gum or drinking carbonated beverages can also introduce air into the stomach and cause belching. Because infants frequently swallow air when feeding, burping or belching is normal after they have been fed. The act of burping an infant helps relieve the discomfort caused by swallowed air.
