Bowel prep with enema in hospital

https://kingstonhospital.nhs.uk/information/bowel-prep-with-enema-in-hospital

Red warning circle saying no bowel preparation means no procedure

A sigmoidoscopy is done to have a look inside the lower part of your bowel. For this, the bowel must be completely empty.

You must prepare properly

Six hours before the procedure, you will need to start ‘bowel preparation’ to empty the bowel. You will then be given an enema when you arrive at hospital to wash out your lower bowel.


6 hours before the appointment

• Have a light meal, such as a sandwich or soup and bread.
• Then have nothing else to eat until after the appointment.
• Drink only clear fluids from now (see box A, below).

4 hours before

• Stop all fluids apart from sips of water

2 hours before

• Stop all fluids
These instructions are very important. If you do not stick to them, we will probably have to cancel the procedure because we will not be able to see inside your bowel clearly.

Contact the endoscopy nurse helpline if you have any questions.

Having the enema

You will be given an enema at the hospital when you arrive. You will need this even if you have recently opened your bowels.

An enema is a liquid that is passed into the back passage (rectum). This will make you open your bowels. It may take 30 minutes to 1 hour for the enema to be fully effective.

You will have access to a toilet in the unit whilst you are waiting. Do not worry if you do not open your bowels.
