Constipation with bleeding should be given in two ways: First, for the treatment of constipation, consider giving lactulose oral solution, 10 ml once, 3 times a day. Bifidobacterium bifidum live capsules, 2 capsules once, 3 times a day. If the symptoms are not relieved, you need to give oral compound polyethylene glycol electrolyte dispersion, divided into flushes. Second, give medication to stop bleeding. Clinically, Yunnan Baiyao is commonly used, 2 capsules once, 2-3 times a day. If the bleeding is not relieved by oral medication, it is necessary to improve the colonoscopy to further clarify the site and cause of bleeding, and to provide symptomatic treatment for the cause, as well as to improve the routine blood and coagulation tests. If the bleeding is not relieved repeatedly, intravenous fluids should be given, and intravenous hemostatic drugs should be given for symptomatic treatment, such as phenolsulfonamide or aminobenzoic acid are commonly used in clinical practice.
