The most common normal cause of belching is excessive gas in the stomach that comes from swallowed air. 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.
Persistent belching could be a sign of digestive conditions that require medical treatment.
