Colonoscopy is a common procedure used to examine the large intestine (colon) and rectum. It helps doctors investigate symptoms, detect abnormalities, and screen for conditions such as bowel polyps and colorectal cancer.
A colonoscopy is a procedure that allows a specialist to examine the lining of the large intestine using a thin, flexible tube called a colonoscope. The colonoscope has a small camera that sends images to a monitor, allowing the specialist to check for inflammation, polyps, bleeding, or other abnormalities. Colonoscopy is commonly used to investigate symptoms such as changes in bowel habits, abdominal pain, rectal bleeding, or unexplained anaemia. It is also used for bowel cancer screening.
Before the procedure, you will receive medication to help you relax and remain comfortable. Many patients receive intravenous sedation, meaning you will be drowsy but still breathing on your own.
During the colonoscopy, the specialist gently guides the colonoscope through the colon while viewing images on a screen. Air or carbon dioxide may be introduced to expand the bowel and allow clear viewing of the lining.
If polyps or abnormal tissue are found, they can often be removed during the procedure and sent for testing.
After the procedure, you will rest in our recovery room while our nursing team monitors you as the sedation wears off.
You may experience mild bloating or cramping due to the air introduced during the procedure, but this usually settles quickly. Most patients are able to go home once they feel alert and comfortable.
If you have received sedation, you must arrange for someone to drive you home, as you will not be able to drive for 24 hours.
You should avoid making important decisions, operating machinery, or drinking alcohol during this time.
Most people are able to return to normal activities the following day unless advised otherwise by their doctor.
Contact your doctor if you experience:
These symptoms are uncommon but should be checked promptly.
Colonoscopy is generally a safe procedure, but like all medical procedures it carries some risks.
Possible complications include bleeding, infection, or a tear in the bowel wall. These complications are uncommon, and your specialist will discuss any risks with you before the procedure.
Proper bowel preparation is essential for a successful colonoscopy. The bowel must be completely clean so the specialist can clearly see the lining of the intestine.
This usually involves dietary restrictions and medication the day before the procedure.
