Patients whose stools are dilute every day should first rule out any disturbance in their dietary habits, for example, some patients especially like to eat cold, stimulating, such as ice-cream, ice cream, chili-related things, which will cause irritation to the gastrointestinal mucosa and will result in such performance of unformed, pasty stools. If there is no such condition and the patient’s condition is greater than six months, it is recommended that the patient further improve the stool examination for chronic inflammatory infections or other parasitic infections. If all these conditions are ruled out, it is necessary to refine the e-colonoscopy. If the colonoscopy reveals polyps, it is considered to be related to the chronic inflammatory irritation caused by the polyps. If there are no polyps, there is no ulcerative colitis, and there are no related diseases such as intestinal tuberculosis. In other words, if these organic lesions are excluded, it is necessary to consider the possibility of functional lesions, the most common of which is irritable bowel syndrome. Irritable bowel syndrome may be related to the patient’s mood, mental state, eating habits, and even the patient’s physical condition. Patients need to adjust the intestinal function is a relatively long process, it can be recommended to give intestinal flora regulators, the most common is Jin Shuang Qi, Mei Chang An and other such drugs, or with the anti-diarrheal Similac and so on, these drugs to slowly regulate. The essence of this functional disease is actually that the intestinal mucosa is more sensitive to cold, cool, or slightly higher than room temperature food will be more sensitive and more reactive, which can be interpreted as an allergic phenomenon.
