A 37-year-old member asked:

What causes blood in stool?

5 doctor answers10 doctors weighed in
Dr. Carlos Encarnacion
Medical Oncology 35 years experience
A lot of things: Many things can cause blood in the stool (i presume you talk about bright red blood and not black tarry stools) including simple things like hemorrhoids or fissures or more serious things like colitis, polyps, or even cancer. Any blood in the stool should be evaluated. Visit your family doc and he/she will likely send you to a gastroenterologist. Best to you.
Dr. Heidi Fowler
Psychiatry 25 years experience
Blood in stool.: Possible causes of blood in stool include: fissures, fistulas, hemorrhoids, cancer, ulcers, infections, inflammation, Diverticular disease & Angiodysplasia . Get evaluated if more than a one time occurrence.
Dr. Sidney Vinson
Gastroenterology 27 years experience
Lots of things: The most common causes of blood in the stool are hemorrhoids and an anal fissure (tear in anus). Other causes include cancer, poyps, diverticulosis, angioectasia and colitis. Anyone with blood in their stool should discuss this with their doctor as further evaluation is necessary.
Dr. Jan Rakinic

See doctor: Rectal bleeding is not normal and should always be evaluated. See a colorectal surgeon, who will do a complete evaluatin and examination, and can treat most causes of rectal bleeding.
Dr. Eric Kaplan
Colon and Rectal Surgery 42 years experience
Hemorrhoids: Usually but can be many other things including infection, inflammatory bowel disease and tumors, both benign and malignant. See a colorectal surgeon sooner rather than later.

Not normal, get help: Blood in stool is a warning sign. Brisk bleeding warrants emergency care. Causes of bleeding may be predictable (e.G rectal trauma), but evaluation is always appropriate. A rule of thumb (but not absolute): black stool means bleeding comes from upper GI tract; grape jelly stool from small bowel; silver stool from biliary tree; burgundy stool from right colon; red blood from left colon to anus.
A 46-year-old member asked:

Can palafer cause blood in stool?

1 doctor answer1 doctor weighed in
Dr. Shaad Abdullah
Hematology and Oncology 17 years experience
No: Palafer usually refers to iron supplements. It can make your stool appear black and possibly look like bleeding but usually i would expect such a medication being used for people who have blood loss from other causes such as GI related diseases. Patient should see a local gastroenterologist if any signs of bleeding reported in the stool.
