A flexible sigmoidoscopy looks at the rectum and the left side of the colon and is often used to investigate symptoms such as persistent diarrhoea or change in bowel habit or bleeding from your back passage.
If Miss Gupta recommends a flexible sigmoidoscopy, you will need to have an enema to clear out the lower bowel. The procedure will then be carried out while you are awake and without the need for sedation or pain relief, and usually only takes 10 to 20 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.
