Thank you all again for the info. I may not have clearly indicated that I would not be fasting for 5 days prior but stated the instructions indicate what to eat and not eat for 5 days prior. They have given me a separate set of instructions and I am only not to take my insulin the night before the colonoscopy. In looking at the cases of colo-rectal cancer, there are approximately 50,000 people a year who die from this so I have decided I am going to go ahead and be screened. I do worry about the 12 hours of clear liquids but am sure I will find healthy clear broths that are good. I have a history of different types of cancers in my family so another reason I decided to go ahead with this. It will be in December.

Thank you all again for your advice and input. I appreciate it so much.

My HMO has decided that since there is NO history of colon cancer in my family, and because of my diabetes, that until I fail my yearly occult fecal test, it would be just fine to not have that colonoscopy at this time. That is alright with me, because I don't believe i can go 24 hours on clearliquids. I have a hard time going 12 hours [for lab tests]. Plus, when I skip my insulin, I notice my numbers rise. Strange, but true. If. for instance, I miss breakfast, and my numbers was in the 90 range at that time of day [I tested it to know], the next time I tested for dinner, it was in the 130 to 140 range.

I was so incensed by the prep instructions you quoted that I left out the very important word NOT in my first line!  NO NO NO NO ONE fasts for 5 to 7 DAYS before a colonoscopy and that makes no sense whatsoever.  Nor does any responsible practitioner advise an insulin-using diabetic to not take any insulin for 24 hours or 12 hours or whatever; your diabetes care manager will help you calculate a REDUCTION, and your must check you blood sugar before being sedated, someone should check it again during the procedure, and immediately afterward, and be prepared to give you glucose IV until you have recovered from the sedation sufficiently to safely eat.  That is, IF there is a true need for this procedure, and the reason is not just "well, you're 5o, and the incidence of colon cancer rises after 50."  The incidence of ALL cancers rises after age 50, but we don't have routine lung biopsies or ovarian biopsies or breast biopsies or pancreatic biopsies!  Nor do men have prosatte biopsies as a screening method!  Make an informed decision to protect your own health, but don't consent to something that has risks in itself, is expensive, invasive, and uncomfortable and requires sedation or anesthesia just "because we can do this."   I've been using insulin for 46 years, and I am a cancer survivor--not colon cancer-- and had to make several decisions about my treatment options.  I researched for myself (in the medical library of the Univeristy medical school), educated myself, and decided what was best for ME at my particular stage of life.

Hi, Lena!  The instructions you quoted do make sense at all for ANY colonoscopy!  Are you sure you have them correctly?  The standard is NO RED MEAT for the prior 3 days, taking the Movi-Prep, and fasting for the following 12 hours! Unless you are at high risk for colon cancers--like you have strong family history or already have some type of bowel disease symptoms--ask about  doing a HemOccult (that's a brand name) or a FIT (that's the generic) test FIRST, and then doing the colonoscopy only if that result indicate the need. Colonoscopy and sigmoidoscopy are expensive, uncomfortable, and invasive procedures and really should have a clear indication for them, especially for persons for whom the procedure itself poses a risk!  I have followed my own advice regarding colonoscopy, and just repeat the FIT every other year.  I know we have all been swayed by stories like Dr Oz and his polyps, and Sharon Osbourne who did actually have cancer.  But, Sharon O had symptoms AND a positive FIT before her colonoscopy was scheduled.  It IS true that for the insulin-using diabetic, the preparation and procedure of the colonoscopy can cause  dangerous electrolyte imbalances, analogous to what an illness causing severe diarrhea, vomiting, and dehydration does.  If you can afford it, or your insurance covers some costs, considr having the "virtual colonoscopy" imaging, which does not require the violent emptying of the colon and has been proven to be very highly effective in visualizing suspiscious growths and possible cancers in the colon, sigmid, and rectum.

And have whoever helps you manage your diabetes school this guy!

I just had a colonoscopy last week and the  only time they didn't want me to take my insulin was the night before the procedure if my blood sugar was below 140.  I don't understand why they told you not to take insulin for that long before the procedure.  It makes no sense and can be very dangerous.  I think you might want to get a referral to have a different doctor perform the colonoscopy - someone who understands diabetes.  I also want to mention the importance of testing frequently during the day you are fasting.  I tested every couple of hours and drank something with sugar and ate jello (with sugar) to keep my glucose within a safe range.  I was dreading the procedure, but it's really not that bad.  Good luck and please don't put it off too long.   A colonoscopy saved my mother's life.

Thanks very much everyone. I had given this office all my diabetic information and that's why I was a bit alarmed.

I will contact them again and see if they can give me different instructions.

I appreciate this very much. It was my very first post and didn't have to wait long for help.

Thanks :)

SarahLouise is right.  You should call them.  I tried to get the specialist to talk to me about diabetes and just pushed me off to his employee that didn't listen to me well and get specific about insulin dependent diabetes.  But I do remember that I was told to take stool softener, big jug of laxative fluid, and to only eat broth, jello the day before.  Nothing that morning.  I didn't have the courage to carry through on it.  I don't think that there would have been a high even if I had stopped the insulin.  I was worried about a low for the day before and the day of the procedure.

Stopping insulin was Not one of the requirements for my colonoscopy, I had one about 3 years ago.  I talked with the nurse about my diabetes and was given a different set of instructions.


Call them.
