The following matters need to be noted after polyp removal: First, patients need to pay attention to rest and do not engage in strenuous activities, otherwise it will lead to bleeding from the trauma. Second, observe the recovery of the patient, mainly observe whether there is abdominal pain and blood in the stool. Third, pay attention to the diet, patients should not eat spicy, stimulating food, such as chili peppers, etc., do not eat hard food, such as nuts, etc. Fourthly, the polyps will be examined pathologically to be able to determine whether the polyps are cancerous. Polyp is very common, and after this disease occurs, it needs to be removed surgically in time, if not, the polyp may increase in size, and the polyp may become malignant. Once malignant, the patient’s prognosis is very poor. It is recommended that endoscopic polypectomy be performed in time to completely cure the disease.
