Is rectal bleeding always caused by hemorrhoids?

No. Hemorrhoids are a frequent cause, but fissures, polyps, inflammatory bowel disease and colorectal cancer can produce similar bleeding. Examination is required to distinguish them.

Can I wait if the bleeding stops on its own?

Bleeding that stops does not exclude an underlying condition. Recurrent or unexplained bleeding should still be assessed.

Is colonoscopy always necessary?

Not always. The indication depends on age, risk factors, examination findings and the character of the bleeding.

Rectal Bleeding: Possible Causes and Evaluation

Rectal bleeding means blood seen on toilet paper, on the stool or in the bowl during or after defecation. Causes range from benign and self-limiting conditions to disorders that require prompt assessment. Colour, amount and accompanying symptoms guide the evaluation.

Common causes

Hemorrhoidal disease — bright red blood after defecation
Anal fissure — sharp pain with hard stools and small amounts of blood
Anal fistula or abscess — discharge that may be blood-stained
Colon polyps — often painless, intermittent bleeding
Colorectal cancer — bleeding with bowel habit change or weight loss
Inflammatory bowel disease — bloody, mucous diarrhoea
Diverticular disease — sudden, painless, heavier bleeding

How the evaluation proceeds

Assessment starts with a detailed history and physical examination. Depending on findings, anoscopy, rectoscopy or colonoscopy may be advised. Identifying the source of bleeding is the decisive step before any treatment plan is made.
