What does rectal bleeding look like?

You may notice blood in the stool, in the toilet bowl water or on the toilet paper.  It can range in colour from bright red, to dark red (maroon) or even black. 

Sometimes, blood in the stool may not be visible to the naked eye.  It may be identified on a stool sample test.  This is called a faecal occult blood test.  An example of this is the National Bowel Cancer Screening Program, a government initiative currently provided to people aged 50-74.

What causes rectal bleeding?

There are several possible reasons for rectal bleeding.  Bleeding may come from the conditions in the gastrointestinal tract (gut) or from conditions in the anus.

Conditions in the gastrointestinal tract that may cause rectal bleeding include polyps, tumours, infection, inflammation, ulcers and diverticular disease.

Conditions in the anus that may cause rectal bleeding include haemorrhoids (piles), anal fissure, anal fistula, polyps and tumours.

How do I find the cause of my rectal bleeding?

It may be possible to get an idea of the most likely reason(s) for rectal bleeding based on your age, symptoms, any family history of gastrointestinal conditions and a physical examination of the abdomen and anus.

To confirm the cause, an inspection of the gastrointestinal tract is recommended.  This is performed with a camera, such as a gastroscopy or colonoscopy.
