Rectal Bleeding
Table of Contents
Rectal bleeding can be a concerning symptom, whether you notice a few spots of blood on toilet paper or see bright red blood in the toilet bowl. While not always a medical emergency, it is important not to ignore rectal bleeding. It can be a sign of common, easily treatable conditions like haemorrhoids, or it may indicate something more serious that requires specialist attention.
In this article, Dr. Goutham, a Brisbane-based general surgeon at Upper Edge Surgery, explains the possible causes of rectal bleeding, when you should seek medical advice, and how a colonoscopy or other investigations can help get to the bottom of the problem.
What is Rectal Bleeding?
Rectal bleeding refers to any bleeding that occurs from the rectum or anus. It can appear in several ways:
Bright red blood on toilet paper after wiping
Blood in the toilet bowl after a bowel movement
Blood streaks on stool
Dark or maroon-coloured stools (less common, may suggest bleeding higher up in the digestive tract)
The amount of blood can vary. Even small amounts of bleeding should not be dismissed, especially if it recurs or is accompanied by other symptoms such as pain, changes in bowel habits, or unexplained weight loss.
Common Causes of Rectal Bleeding
Many conditions can lead to rectal bleeding. Some are minor and easily treated, while others may require further investigation and management by a specialist like Dr. Goutham.
1. Haemorrhoids (Piles)
Haemorrhoids are one of the most common causes of rectal bleeding, especially in Brisbane, where a busy lifestyle and dietary factors can contribute to bowel issues.
Haemorrhoids are swollen veins in the lower rectum or anus. They can be internal (inside the rectum) or external (around the anus). Straining during bowel movements, constipation, prolonged sitting, or pregnancy can all contribute to haemorrhoid development.
Symptoms may include:
Bright red blood after a bowel movement
Itching or discomfort around the anus
Lumps or swelling near the anus
Mucus discharge
2. Anal Fissures
An anal fissure is a small tear in the skin around the anus, often caused by passing hard stools or constipation. Fissures can cause sharp pain during bowel movements and bright red bleeding.
3. Diverticular Disease
Small pouches (diverticula) form in the colon wall
If inflamed (diverticulitis), can cause bleeding and abdominal pain
4. Inflammatory Bowel Disease (IBD)
Conditions like Crohn’s disease or ulcerative colitis cause chronic inflammation
Symptoms: Diarrhoea, abdominal cramps, rectal bleeding
5. Colorectal Polyps
Polyps are growths on the lining of the colon or rectum. While many polyps are harmless, some can develop into colorectal cancer over time. Polyps often do not cause symptoms, but when they do, rectal bleeding may be one of them.
A colonoscopy is the gold standard test for detecting and removing polyps, significantly reducing the risk of bowel cancer.
6. Gastroenteritis & Infections
Bacterial or viral infections can irritate the digestive tract
May cause bloody diarrhoea
7. Angiodysplasia
Abnormal blood vessels in the colon that bleed
More common in older adults
8. Colorectal cancer
Although less common, rectal bleeding can sometimes be a sign of colorectal cancer. This is why ongoing or unexplained bleeding always warrants investigation, especially for people over 45 or those with a family history of bowel cancer.
Other warning signs may include:
Unexplained weight loss
Abdominal pain
Changes in bowel habits (diarrhoea or constipation)
Feeling that your bowels do not empty completely
When Should You See a Doctor for Rectal Bleeding?
While not every episode of rectal bleeding is an emergency, there are situations where you should consult a doctor promptly:
Recurrent or persistent rectal bleeding
Large amounts of blood or clots in the stool
Associated abdominal pain, bloating, or cramping
Unexplained fatigue, weakness, or weight loss
Personal or family history of bowel cancer
You are over 45 years of age and have not had recent bowel screening
If you are experiencing rectal bleeding in Brisbane, Dr. Goutham at Upper Edge Surgery can assess your condition and arrange appropriate investigations, including colonoscopy, to identify the cause.

FAQs About Rectal Bleeding
Can stress cause rectal bleeding?

Spicy foods, alcohol, and low-fibre diets can aggravate bleeding. Increase water and fibre intake.
How quickly should I see a doctor for rectal bleeding?
