Some people suffer from gastric prolapse, when excessive intake of food, the degree of gastric prolapse will be more serious, which will affect the gastric peristaltic function, thus causing pain in the stomach. Many people will have chronic inflammation on the gastric mucosa, and then too much intake of food, food in the digestive process will cause friction on the stomach wall, resulting in congestion and edema of the stomach wall more serious, which will cause a sense of pain. Some people consume a lot of fatty foods in their diet, and fat requires bile and pancreatic juice for digestion. Once bile and pancreatic juice are secreted excessively, it will affect the discharge of bile and pancreatic juice, thus triggering attacks of cholecystitis and pancreatitis.
