Colonoscopy in Brisbane
In short
A colonoscopy is the gold-standard test for examining the large bowel — used to investigate symptoms such as bleeding, pain or a change in bowel habit, and to screen for and prevent bowel cancer by removing polyps before they can become cancerous. It takes about 20–30 minutes under gentle sedation, and most patients go home the same day. Performed by Dr Goutham Sivasuthan, specialist surgeon — an Australian-trained, GESA-accredited General and Endoscopic Surgeon. Most insured patients pay no gap for the surgeon’s fee.

A clear view of your large bowel
A colonoscopy examines the inside of the large bowel (colon) using a flexible instrument with a small high-definition camera and light at its tip. It is gently passed through the back passage and guided through the colon so the bowel lining can be viewed in detail.
During the examination, Dr Goutham carefully inspects the bowel for abnormalities such as polyps, inflammation, ulcers, bleeding and tumours. If needed, biopsies can be taken and polyps removed in the same procedure — which is what makes colonoscopy both a diagnostic and a preventative test.
Reasons a colonoscopy may be recommended
A colonoscopy may be recommended to investigate symptoms affecting the digestive system, or to screen for bowel cancer. Common reasons include:
- Blood in the stool or rectal bleeding
- Unexplained iron deficiency anaemia
- Persistent diarrhoea or ongoing constipation
- Unexplained abdominal pain or a change in bowel habits
- A family history of bowel cancer
- A positive bowel screening (FOBT/FIT) test
- Surveillance after previous polyps
Many patients also choose colonoscopy as part of preventative bowel cancer screening, particularly from age 45–50 or with a family history. If symptoms point to the upper gut as well, a gastroscopy can be performed at the same visit.

Early detection saves lives
In Australia, bowel cancer is one of the most common cancers — but also one of the most preventable when detected early. It may cause no symptoms in its early stages, which is why screening colonoscopy plays such an important role.
Polyps are fleshy growths on the bowel lining. While most are benign, some can slowly develop into cancer over time. During colonoscopy, polyps can usually be removed immediately (polypectomy) — one of the most effective ways to prevent bowel cancer. Possible signs worth checking include rectal bleeding, a persistent change in bowel habit, unexplained anaemia, fatigue or unintentional weight loss.
What happens during a colonoscopy
After following clear bowel-preparation instructions beforehand, you are admitted to the endoscopy unit and meet the anaesthetist. The procedure is performed under sedation, so you rest comfortably and generally remember little or nothing of the examination.
- The colonoscope is gently inserted and the colon lining carefully examined.
- Polyps can be removed and biopsies taken if needed.
- Certain problems, such as bleeding, can be treated during the same procedure.
- The colonoscopy itself usually takes 20–30 minutes.
The total time at the hospital or day-surgery centre is generally two to three hours, allowing for admission, the procedure and recovery from sedation.
Recovery after your colonoscopy
After the procedure you rest in the recovery area while the sedation wears off. Most patients can eat and drink soon afterwards, go home the same day, and return to normal activities the following day. Some mild bloating or wind pain from the air used during the procedure is common and settles quickly.
You will receive information about the findings before leaving, and any biopsy results are reviewed with you and your GP once available. Because sedation is used, you will need someone to drive you home and should not drive for the rest of the day.
Colonoscopy as part of whole gut health
At Colonoscopy Brisbane, colonoscopy is part of a broader approach to digestive health. Many symptoms can arise from a range of conditions — inflammatory bowel disease, coeliac disease, gut microbiome imbalance, functional gastrointestinal disorders, food intolerance or enzyme deficiencies.
If colonoscopy findings are normal but symptoms continue, a gut health assessment can look further — including gut microbiome testing, dietary assessment or additional investigations such as capsule endoscopy.
