Rectal Bleeding in Brisbane
In short
Rectal bleeding should always be assessed. Most cases are due to benign causes such as haemorrhoids, anal fissures or polyps, but bleeding can also be the first sign of bowel cancer — so it is never safe to assume the cause without a proper examination. A colonoscopy lets Dr Goutham find the exact source and rule out higher-up causes. Where haemorrhoids are responsible, they can often be banded during the same procedure — one visit, both done. Assessment is especially important if you are aged 45 or older, or have anaemia, weight loss, a change in bowel habit, or a family history of bowel cancer.
What causes rectal bleeding?
Bleeding from the back passage can come from the anus, the rectum or higher in the bowel. The colour and pattern can give clues, but they are not reliable enough to diagnose the cause on their own. Common causes include:
| Cause | Typical pattern |
|---|---|
| Haemorrhoids | Bright red blood on the paper or in the bowl, often painless |
| Anal fissure | Bright red blood with sharp pain on passing a motion |
| Polyps | Often no symptoms; can bleed intermittently |
| Diverticular disease | Can cause sudden, heavier bleeding |
| Inflammatory bowel disease | Blood mixed with mucus, with diarrhoea or pain |
| Bowel cancer | May cause bleeding, a change in bowel habit, or anaemia |
Because these causes can look similar, the only reliable way to know which one is responsible is a proper assessment.
Never assume it’s “just haemorrhoids”
It is tempting to put rectal bleeding down to haemorrhoids, especially if you have had them before. But haemorrhoids are very common, which means they can be present at the same time as another, more important cause. Assuming the bleeding is from haemorrhoids without ruling out higher-up causes is one of the most common reasons a serious diagnosis is missed or delayed.
In Australia, bowel cancer is one of the most common cancers — and one of the most preventable when found early. Rectal bleeding can be its first and only warning sign. A colonoscopy allows the whole large bowel to be examined so that polyps can be removed before they become cancerous and any other cause is identified.
Get assessed sooner if any of these apply
The threshold for a colonoscopy is lower — and the importance higher — if you also have:
- Age 45 or older
- Iron deficiency or anaemia
- Unexplained weight loss
- A persistent change in bowel habit
- A family history of bowel cancer or polyps
- Blood mixed through the stool (rather than only on the paper)
Finding the exact source
Assessment begins with a consultation and examination. Depending on your age, symptoms and history, Dr Goutham will recommend the right test to identify the source safely:
- Colonoscopy — the most thorough test, examining the entire large bowel, allowing polyps to be removed and biopsies taken, and haemorrhoids to be treated in the same procedure.
- Gastroscopy — considered if an upper-gut source is suspected, for example with anaemia or black, tarry stools.
- Capsule endoscopy — used when bleeding is not found at standard scopes and a small-bowel source is suspected.
Using advanced endoscopic imaging, the cause can usually be pinpointed quickly so that the right treatment can begin.
Diagnose and treat in one visit
When haemorrhoids are confirmed as the source, they can often be treated during the same colonoscopy using rubber-band ligation (banding) — a quick, minimally invasive technique that cuts off the blood supply to the haemorrhoid so it shrinks and settles. Treating the haemorrhoids at the same time as the diagnostic colonoscopy means:
- One procedure instead of two
- Fewer hospital visits and less time off
- Faster relief and recovery
- Reassurance that the rest of the bowel has also been checked
Haemorrhoids are graded from I to IV by size and whether they protrude. Banding is well suited to lower-grade internal haemorrhoids; larger or more advanced cases may need a different approach, which Dr Goutham will discuss with you. Simple measures such as more fibre, adequate fluids and not straining also help prevent them returning.
When rectal bleeding is an emergency
Most rectal bleeding is not an emergency, but seek urgent medical care — for example at your nearest emergency department — if you have:
- Heavy or continuous bleeding
- Light-headedness, fainting, or a racing heartbeat
- Black, tarry stools, or vomiting blood
- Severe abdominal pain with the bleeding
For bleeding that is lighter but ongoing or recurrent, it is still important to be assessed rather than waiting to see if it settles.
Thorough assessment, efficient treatment
Diagnose and treat together
As a GESA-accredited endoscopic surgeon, Dr Goutham can both identify the cause and band haemorrhoids during the same colonoscopy — avoiding a separate procedure.
Safety first
The whole bowel is examined so serious causes are not missed — never assuming bleeding is “just haemorrhoids”.
