Patient guide · Procedure prep
A colonoscopy is one of the best ways to check the health of your large bowel and to find and remove polyps before they can cause harm. Good preparation makes the test safer, quicker, and more accurate — here's exactly what to do.
A thin, flexible tube with a small camera is passed gently through the back passage to examine the entire large bowel (colon). You'll usually be given sedation so you're relaxed and comfortable. If any polyps are found, they can often be removed during the same procedure. The examination itself typically takes 20–45 minutes.
The bowel must be completely clean for the camera to see clearly. If preparation is incomplete, small polyps can be missed — and occasionally the test has to be repeated. The effort you put into the prep directly affects how good and how safe your colonoscopy is.
Your specific bowel-cleansing medicine, dose, and timing will be given to you by the clinic when your colonoscopy is booked. Follow those instructions precisely — they are matched to your appointment time. The steps below explain the general pattern.
Your motions should gradually become clear or pale yellow, like tea without milk — the sign you're well prepared.
Contact the clinic beforehand if you have significant heart, kidney or liver disease, if you are diabetic, if you might be pregnant, or if you have ever reacted to sedation. These aren't reasons to cancel — just things we plan around to keep you safe.
Most people feel little or no pain. Sedation keeps you relaxed and drowsy, and many remember very little afterwards. Some bloating or cramping from the air used settles quickly.
Most can be continued, but blood thinners, diabetes medicines and iron often need adjusting. Confirm with the clinic in advance rather than stopping anything yourself.
Some nausea is common. Slow down, take smaller sips, and take short breaks. If you vomit repeatedly or can't keep it down, contact the clinic.
Dr. Maaz usually explains the main findings straight after, once the sedation wears off enough to talk. Biopsy results follow in a few days.
The clinic team is happy to help you prepare with confidence.
