During the onset of the disease, due to the presence of inflammation on the mucosa of the digestive system, spasm and contraction of the gastrointestinal wall occurs, which is accompanied by pain not only in the intestines but also in the stomach. Secondly, cholecystitis causes spasm and contraction of the gallbladder during the disease, which causes pain. The pain is radioactive and radiates not only to the stomach, but also to the intestine, so that both the intestine and stomach are accompanied by pain. Then pancreatitis during the disease, in addition to causing some involvement to the stomach, the food in the intestine will have indigestion symptoms due to the lack of a series of digestion, and undigested food will cause some stimulation to the intestinal wall when passing through the intestine, so many patients will be accompanied by intestinal pain, diarrhea and other manifestations.
