Hi and welcome to Healthcaremagic. Thank you for your query. I am Dr. Rommstein, I understand your concerns and I will try to help you as much as I can. In most cases, causes of abdominal pain and bleeding through rectum are benign and include hemorrhoids, anal fissure or rectal polyps. These are primarily treated with stool softener, diet and sitzbaths. If there is no improvement in next few weeks, then surgical management should be considered. Other causes may be more serious and include tumors or inflammatory bowel diseases and these should be ruled out with colonoscopy which must be done if there is low blood count present or rapid weight loss. Otherwise, you can see if conservative therapy will help and consult proctologist if necessary I hope I have answered you query. If you have any further questions you can contact us in every time.
