Colonoscopy, General Anesthesia and High Blood Sugar

Hi everyone. I am T1 for 40 years and had a colonoscopy yesterday. Because I am overweight my doctor wanted me to have general anesthesia. The procedure was easy (I don’t remember a single thing about it) Unfortunately, I didn’t get the name of the anesthetic. Now I am having terribly high bg’s (think 350 to 500). I am taking massive doses of insulin (using both pump and injection) and still having troubles. It’s been about a day and a half. Can the anesthesia drug cause this? Will it (hopefully) be over soon? I’m frustrated and a little scared. Right now I am running a 150% basal and taking big corrections. If i could even get down to 200 I’d be much happier right now.

We find stress will raise BG. So your stress on top of the situation may simply be adding on.

My advice. Don’t worry about how much insulin. Dose away. Whatever it takes to drop the BG.

I would also place a call to the doc and find out which anesthesia then place a call to your Endo and discuss the entire situation.

But in the meantime - dose whatever insulin it takes and try to relax.

Push fluids to help flush it out of your system, too. Total speculation on my part as I’ve never had a colonoscopy before, but is it possible the prep dehydrated you a little? Dehydration will keep your sugars high.

I suggest going off the pump for bolus until you get it under control. I doubt it is the procedure. Like others I suggest fluid, calling you doctor and following all instructions.

I heartily second Tim’s advice. Do whatever it takes to get your BG where it belongs, THEN worry about figuring out why this happened.

A dear friend’s endo once told her, “If you can figure out why you’re high or low in ten seconds or less, great. Otherwise just correct and move on.” First things first.

There are a number of different medication cocktails used for colonosopies, depending on where it’s done and what the doctor favors. Probably the most common is a combination of Fentanyl (painkiller) and Versed (anesthetic). It’s the Versed that keeps you from remembering the procedure.

But that may not be the particular mixture your doc used. As suggested above, find that out and then you can research it to learn whether it’s known to affect blood sugar.
