You should not smoke after intestinal polyp surgery. Tobacco contains a variety of substances that can lead to local microcirculation disorders, and after surgery for intestinal polyps, smoking will affect wound healing and postoperative repair. It has been proved that nicotine in tobacco is a carcinogen, which not only causes lung cancer, but also induces or promotes rectal polyps to become cancerous, so smoking is prohibited after intestinal polyp surgery. In addition to quitting smoking, avoid alcohol and other stimulating foods, eat more vegetables and fruits rich in dietary fiber, keep the stool smooth and soft, to avoid postoperative bleeding, appropriate physical exercise and anal lifting exercise, promote local blood circulation, and promote the healing of the wound. Smoking and intestinal polyps are both high incidence factors of colon cancer. Therefore, patients found to have intestinal polyps are advised to quit smoking. After surgery for intestinal polyps, regular outpatient review should be performed.
