The following information aims to assist you in preparing you for your colonoscopy procedure, providing helpful hints for your bowel preparation, explaining what to expect when you go home and when to seek medical help.
Preparation
For a successful colonoscopy it is important the bowel is completely empty. An empty bowel means the doctor is more likely to see the lining of the bowel and detect any problems. Poor preparation may mean the procedure will need to be repeated on another day.

Carer
It is important to arrange to have a ‘carer’ to care for you when you leave hospital. Every patient who has a procedure performed under sedation or general anaesthetic and is leaving hospital within the same day as their procedure needs to be handed over to a carer (over 18 years of age). This person will be responsible for your wellbeing and recovery for up to 24 hours depending on the type of anaesthesia received.
Work arrangements
It is important that you re-arrange your normal activities and take time off for:
- the day of the procedure
- the day after your procedure (if instructed).
A medical certificate will be provided on discharge for yourself and the person responsible for picking you up from hospital and caring for you at home.
Medications and your procedure
Some medications must be stopped prior to your procedure. These instructions will be given by your doctor and listed on your bowel preparation instructions. Ensure you check and follow these instructions.
Being prepared
You will need to start the low fibre diet prior to your colonoscopy.
This reduces the fibre in your bowel, which makes it easier when you start the two day bowel cleansing regime.
Refer to the diet plan for items you can and cannot eat, as well as the below instructions:
- you may eat barley sugar or butterscotch lollies (to use between prep drinks)
- you may like to apply protective cream, e.g. Lanoline or Vaseline (to apply around your anal area to reduce irritation)
- you may choose to use moist toilet wipes (may also soothe the area after using toilet paper).
During your diet and bowel preparation regime
It is important to follow the diet and bowel preparation instructions that have been provided to you. For successful colonoscopy it is very important that the bowel is cleaned well. This will enable the doctor to clearly see the lining of the bowel.
Poor preparation may mean that the procedure will be stopped and you will have to repeat the preparations and procedure another day.

Failure to have a bowel motion
People vary in the time it takes to have a bowel motion after commencing the bowel preparation. To help relieve any concerns about your progress the following information will help guide you.
Helpful hint and tips
- If you become ill or have severe pain seek medical advice from your general practitioner or nearest Emergency Department.
- Hydration is essential for effective colonoscopy prep.
- Drink the solution through a straw.
- Add diet lemon cordial to the preparation mixture.
- Keep warm.
- Some people find that drinking the solution very quickly and then using a “chaser” such as apple juice helps the prep go down easier.
- If you feel nauseated while taking the preparation, stop for half an hour. Have a hot drink and walk around. Resume drinking the solution more slowly.
- If you have haemorrhoids (piles) use your haemorrhoid cream to reduce discomfort.
- Stay near a bathroom.
- If you feel bloated, try walking around. Suck some peppermints or drink peppermint tea.
Day before your procedure:
If you have not had a bowel motion and you are not experiencing pain or vomiting,continue drinking.
