Hi, without physical examination it is difficult to specify the cause but blood in the stool means that
there's some injury or disorder located somewhere in your GI tract. The closer the source of bleeding is
to the anus, the brighter red the blood will be. If the bloody stool is bright red, then it may be due to
hemorrhoids, constipation or anal fissures, but intestinal polyps, inflammatory bowel disease or
diverticulosis can cause significant bleeding. Therefore I advise you to do your ultrasound abdomen, stool
examination, and colonoscopy and consult your physician for these possibilities. Thanks.
