The first thing to consider in this case is constipation. In addition, colon polyps and colon tumors can also cause the above symptoms, which need to be clarified by e-colonoscopy. If colon polyps are detected, electrocoagulation and electrosurgery of polyps should be performed under e-colonoscopy. If it is found to be a colon tumor, surgery or chemotherapy or radiotherapy is required. If colonoscopy does not reveal any lesion, it is mostly considered to be directly related to the patient’s poor bowel habits and slow bowel movement emptying, which can be regulated by diet and improving bowel habits. In terms of diet, patients should be encouraged to eat more vegetables and fruits, less spicy, fried and other stimulating foods, do not drink alcohol, develop the habit of getting up every morning to defecate, and drink a glass of honey water every morning, which is also conducive to the smooth discharge of stool.
