Bowel preparation

Some operations — especially those involving the bowel itself — may require bowel preparation before your procedure. This helps clear the bowel so that the surgical team can work safely and effectively.

One commonly used preparation solution is Moviprep, which is a laxative drink that cleans the bowel by increasing bowel movements and emptying the colon. Moviprep is provided so that your bowel is as clean and empty as possible before your procedure.

How Bowel Preparation works

Bowel preparation normally comes as a powder that you mix with water to make a drink. When you drink the solution, it stimulates frequent bowel actions leading to loose, watery stools. This is a normal effect and part of the cleansing process.

You will be given clear instructions about timing and how much to take based on your appointment time and clinical needs.

It is usual to stay close to a toilet during the preparation period, as the bowel movements occur frequently once the bowel preparation starts working.

Your clinical team will provide detailed instructions tailored to your situation. If you are unsure about how to take your bowel preparation, or if you have particular concerns (for example, related to other medical conditions), please contact your surgical or endoscopy team before starting the prep.

Tips and common experiences

• Continue drinking clear fluids until the time advised by your team — usually stopping drinking a couple of hours before your procedure.
• You may experience side effects such as nausea, bloating, or abdominal cramps. These are common and usually settle as the bowel empties.
• If you feel unwell, very dehydrated, or cannot complete the preparation, contact your clinical team promptly for advice.
• Your bowel preparation instructions may differ depending on the type of surgery or test you are having, so always follow the specific written guidance you are given with your appointment details.
