prepare for a Colonoscopy

It is important that you should allow your doctor to know about any special medical conditions that you may have, before a colonoscopy. Here are some of the conditions that are worth mentioning:

  • Pregnancy
  • Lung conditions
  • Heart conditions
  • Allergies to any medications
  • If you have diabetes or take medications that may affect blood clotting; adjustments to these medications may be required before the colonoscopy.

Never stop taking any medication without first consulting your doctor.

You may need to take antibiotics before the colonoscopy if you:

  • Have an artificial heart valve
  • Have ever been told you need to take antibiotics before a dental or surgical procedure


When you are preparing for colonoscopy you must remember to keep your bowel empty during the process. Your doctor will guide you in this regards, by giving you specific directions about using laxatives the day before the procedure. Different doctors may recommend different laxative regimens, with or without enemas. In some cases, you will also need to follow a liquid diet for one to two days before the procedure with a full fast (nothing by mouth) after midnight the evening before the procedure. Your doctor will give you more exact details about diet when you schedule your colonoscopy exam. You must arrange for a friend or family member to help to take you home as the medication that you receive may make you feel drowsy.
