What should I do if I bleed during a bowel movement? Patients are advised to observe and pay attention to the following questions before visiting the doctor. First, what is the color of the blood? Is it bright red or dark red? Are there any clots? Second, how much blood is there? Is it on the stool paper? Or does it drip out? Or does it come out in jets? Third, how long does the bleeding last? Does it happen for a while? Or is it continuous? How long have the symptoms been like this? Fourth, what are the medications you have used? Remember the above information to provide your doctor with reliable diagnostic information.
