A colonoscopy is used to examine the entire colon, which is also known as the large bowel or large intestine. It can be used to check for conditions such as Crohn’s disease, cancer or benign growths called polyps.

The day before the colonoscopy, you will be given laxatives to clear the bowel out completely, as well as advice about what to eat or drink. Most patients will have a combination of sedation and pain relief during the procedure, which usually takes between 20 and 30 minutes.

In some cases, Miss Gupta may take samples of the tissue from your bowel, called biopsies, which will be used to help diagnose or monitor your condition.

After the procedure Miss Gupta will explain the findings to you and answer any questions you may have. You will also be given a copy of your report, while a further copy will be sent to your GP.
