Burping after eating an upset stomach is usually caused by indigestion, chronic gastritis, gastric ulcer and other diseases. Dyspepsia people will have insufficient secretion of digestive juices, these people’s food digestion and emptying time will be relatively longer, due to the food in the stomach for a long time in the stagnation, so it will be a certain stimulation of the stomach wall, especially in the bad fermentation of food to produce a lot of gas, due to the over-expansion of the gastric body to the diaphragm caused by stimulation caused by hiccups. People with chronic gastritis should try to avoid rough and indigestible food in their diet, which is not only indigestible, but also causes friction to the stomach lining when digested, thus causing stomach discomfort. When the stomach wall is rubbed by the food to produce spasm contraction, it will stimulate the diaphragm to cause hiccups. Gastric ulcer patients in about an hour after food intake, because of food stimulation will secrete a lot of gastric acid, when gastric acid contact with the ulcer surface will cause corrosion of the ulcer surface, which will not only cause pain in the stomach, but also lead to stomach spasm hiccups.
