Burping during stomach pain and venting is good is mainly due to indigestion. When the organism has indigestion symptoms, the ingested food can not be digested and emptied in time, it will stay in the stomach for a period of time, and in the process of staying in the stomach will cause irritation to the stomach causing stomach pain. As the food in the stomach and the stomach acid will be neutralized, fermentation will occur, and the gas in the stomach will gather too much, which will lead to increased pressure in the stomach and cause hiccups, and after the hiccups, the gas will be released partially, and the feeling of bloating in the stomach will be relieved for a while. Indigestion can lead to a large amount of gas in the intestines, causing the intestinal wall to dilate, affecting the blood circulation of the intestinal wall, and also abdominal pain, after the gas is discharged through the anus, the abdominal pressure will be temporarily reduced, and the pain can also be relieved.
