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.
However, discomfort in the abdomen for any reason also may lead to excessive belching. Therefore, belching does not always indicate the presence of excessive gas in the stomach. It is not difficult usually to differentiate between excessive gas in the stomach and other causes of excessive gas. If the problem is gas in the stomach, belching brings relief.
