Prior to a colonoscopy, it is important to inform your doctor of any drug allergy, regular medications (e.g. oral hypoglycaemic drug, anti-coagulant, anti-platelet agent) or pre-existing medical condition (e.g. diabetes mellitus, hypertension, ischaemic heart disease, valvular heart disease, pacemaker in situ). If you are currently on blood thinners, these should be stopped prior to the colonoscopy as advised by your doctor.
To prepare for your colonoscopy, you will be required to follow a bowel preparation process to empty your bowel and fast for six hours prior to your procedure.
- Diet – a low residue diet should be commenced three days before the colonoscopy, avoiding high fiber food such as vegetables, fruits, beans, cereals and dairy product. Stop iron supplements at least three to four days prior to procedure. On the day before the colonoscopy a fluid diet should be commenced (e.g. rice water, clear soup and fluid, avoiding dairy products).
- Laxatives – finish the laxatives provided the night before or in the morning of the day of colonoscopy as prescribed by your doctor to empty the bowel
- Fluids – it is recommended to drink clear fluids to avoid dehydration ahead of your procedure until six hours before the procedure
- Medications – continue to take any prescribed medications unless advised otherwise by your doctor
