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.
Belching is the act of bringing up air from the stomach. Belching is most often a normal process. The purpose of belching is to release air from the stomach. Every time you swallow, you also swallow air, along with fluid or food. The buildup of air in the upper stomach causes the stomach to stretch. This triggers the muscle at the lower end of the esophagus (the tube that runs from your mouth to the stomach) to relax.
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.
