Blood in stools may be due to several causes like hemorrhoids -commonest inflammatory bowel disease , colonic polyps , Anal fissure , cancers of the colon and rectum etc Hemorrhoids can usually be diagnosed from a simple medical history and physical exam. External hemorrhoids are generally apparent, especially if a blood clot has formed. Your clinician may perform a digital rectal exam to check for blood in the stool. She or he may also examine the anal canal with an anoscope, a short plastic tube inserted into the rectum with illumination. If there s evidence of rectal bleeding or microscopic blood in the stool, flexible sigmoidoscopy or colonoscopy may be performed to rule out other causes of bleeding, such as colorectal polyps or cancer, especially in women over age 50. Hemorrhoids home treatment Get more fiber. Add more fiber to your diet from food, a fiber supplement (such as Metamucil, Citrucel, or Fiber Con), or both. Along with adequate fluid, fiber softens stools and makes them easier to pass, reducing pressure on hemorrhoids. Some women find that boosting fiber causes bloating or gas. Start slowly, and gradually increase your intake to 25–30 grams of fiber per day. Also, increase your fluid intake. Exercise. Moderate aerobic exercise, such as brisk walking 20–30 minutes a day, can help stimulate bowel function. Take time. When you feel the urge to defecate, go to the bathroom immediately; don t wait until a more convenient time. Stool can back up, leading to increased pressure and straining. Also, schedule a set time each day, such as after a meal, to sit on the toilet for a few minutes. This can help you establish a regular bowel habit. Sitz.

You can also use a hair dryer to dry the area. Over-the-counter hemorrhoid creams containing a local anesthetic can temporarily soothe pain. Creams and suppositories containing hydrocortisone are also effective, but don t use them for more than a week at a time, because they can cause the skin to atrophy. Witch hazel wipes (Tucks) are soothing and have no harmful effects. A small ice pack placed against the anal area for a few minutes can also help reduce pain and swelling. Finally, sitting on a cushion rather than a hard surface helps reduce the swelling of existing hemorrhoids and prevents the formation of new ones. try all these measure .If bleeding per rectum still continues you need to see a Gastroenterologist for further evaluation
