Instructions for Colonoscopy

The Day Before

If you are having a colonoscopy, your physician will give you instructions on how to prepare for your procedure. You must follow these instructions as closely as possible in order for the physician to perform your procedure. If you have any problems with your preparation, call your physician even if it is after office hours.

If you are a diabetic and are having a colonoscopy, please contact your physician for instructions on how to dose your oral medication and/or insulin before your procedure.

The Day of the Procedure

The morning of your procedure, you may brush your teeth, remembering not to swallow. If your exam is scheduled for the afternoon, your physician may permit a small quantity of clear fluids four hours before the procedure. Clear liquids include water or apple juice. Please check with your physician before having any liquids.

After your procedure, plan on remaining at home for the rest of the day. The day after your exam, you can resume all of your usual activities.

You must have an adult family member or friend available to drive you home as you may likely be a bit too drowsy to drive. Failure to have someone available to drive you home may result in cancellation of your procedure.

You can expect to be at Hamilton Endoscopy & Surgery Center for approximately 2-3 hours, barring any unforeseen delays. The adult driving you to and from the Center is recommended to wait for you at the Center, if possible.

Frequently Asked Questions 

What should I expect upon arrival for my procedure?
Upon arrival at our outpatient center you will be required to fill out and sign registration forms.  At this time you will present your insurance card(s) and be given a band to wear on your wrist that identifies who you are and who your physician is. 
Once you are registered, you will be escorted to the pre-surgical area where you will change into a hospital gown.  At this time you will meet the various staff members who will be caring for you, including our anesthesiologist before, during and after your procedure.  At this time, your vital signs will be checked and monitored, any other preparations will be made and an intravenous line will be established through which fluids and medications can be administered.
Once this is complete, the anesthesiologist will meet with you briefly to discuss your health history, the type of procedure you are having and the type of anesthesia you will be receiving.  It is at this time you can ask any questions. You are then taken to the procedure room where the anesthesia is administered and the procedure is performed.

What should I expect after my procedure at Hamilton Endoscopy?


Following your procedure, you will be taken to our recovery area. The first phase of recovery is to allow the patient to awaken from anesthesia in a calm and relaxed atmosphere, therefore this area is limited to staff only. This time also allows the physicians and nurses to properly monitor you as you recover from anesthesia and provide any necessary medications. Once you are awake, your physician will speak with you about how the procedure went, the expected outcome as well as the expected recovery period.  Your physician will also provide any instructions on what to do over the next few days. We will ask anyone waiting for you to come in to see you once you are fully awake.


Are there any side effects?


Our anesthesiologist will discuss the risks and benefits associated with the different anesthetic options, as well as any complications or side effects that can occur with each type of anesthetic.  The risk of nausea after receiving the anesthetic is extremely low for your procedure because the anesthetic medication that you get has anti-nausea properties.  You may have some discomfort after a colonoscopy because of some residual air in your body,which will pass eventually.
