Colonoscopy Sedation (Entonox Only) Advice on Discharge

You have had this procedure today without sedation.

If you have inhaled Entonox during the procedure, you must not drive for 30 minutes after the last inhalation.

Unless otherwise instructed by your doctor, you may resume your normal diet. You are advised to have a plain diet for the next 24 hours, as you might experience diarrhoea until the bowel settles down from the procedure.

You may resume your normal prescription medicines unless otherwise advised on discharge.

There may be some slight soreness in your bottom and abdomen where the instrument has been but this will wear off in a day or so.

Some bloating may be experienced if air has remained in your bowel. This is not something to worry about; it will resolve itself naturally over the next few hours. However, if it gripes you, having a hot drink, or taking some peppermint tea/water and walking around, might help to provide some relief.

Light bleeding from your bottom may be experience if you have had biopsies taken or polyps removed. It may be spotting on the toilet paper or drops in the toilet which should settle in a day or two.

FOLLOWING THIS PROCEDURE YOU MUST NOT DONATE BLOOD FOR 4-6 MONTHS

The reason for this is that your ability to donate blood in the future is dependent upon your diagnosis and the possibility that you might need to undergo further investigations or complete treatments (British Society of Gastroenterology, 2019).

National guidance recommends that you do not fly for 2 weeks following this procedure.
