Stomach bouts are caused by an attack of gastritis, while diarrhea is caused by enteritis. You should pay attention to hygiene and cleanliness when eating, and especially avoid eating food that has been spoiled and contaminated with bacteria. When food enters the digestive system pathogenic bacteria as well as bacteria can multiply in the stomach and intestines, which can cause irritation to the mucous membrane of the stomach wall and induce gastritis disease. When food enters the digestive system, it also affects the intestinal flora of the intestinal system, causing abnormal spasms and increased peristaltic speed in the intestine, which rapidly expels food residues from the digestive system, and the patient will exhibit diarrhea symptoms. When these symptoms appear, they can be judged by routine stool and blood tests, and for diarrhea symptoms determined to be due to bacterial infection, they can be treated with cimetidine and haloperidol.
