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.
This is because excessive air in the stomach often is the cause of mild abdominal discomfort; as a result, people belch whenever mild abdominal discomfort is felt, whatever the cause. If the problem causing the discomfort is not excessive air in the stomach, then belching does not provide relief.
