I was diagnosed with LADA in March of 2019. I take one 0.5 mg tablet of Prandin, one 100 mg tablet of Januvia and one 500 mg tablet of Metformin every morning, no insulin. I take a second 500 mg tablet of Metformin with dinner and five, six or seven units (depending upon my bedtime blood glucose number) of Basaglar before bed.
I am scheduled for a colonoscopy on the 18th of this month. I am not sure about how to proceed. It is clear in the instructions that I am not to take any of my oral medications the day of the prep or the day of the procedure. The instructions say to take one half my insulin dose on prep day and one half on procedure day. I assume that means I take half the dose of insulin before going to bed on prep night and just don’t take any before the procedure, which is scheduled for very early the next morning.
But what if my bg is very low when I test before bed on prep night? Or high because of the prep and clear liquids? And shouldn’t I be drinking non-diet soda so I don’t get a low bg? The instructions say I should test my bg before leaving my house on the day of the procedure and call my “Doctor or Endocrinologist if the sugar is under 65 or over 300.” (That doesn’t even sound doable at 5:30 am. Timing is a problem if my procedure is scheduled is at 6:30 am.)
And what if I have a very low bg in the morning? I can’t eat or drink anything until after the procedure according to the instructions.
What I want to avoid is getting to the test center and being told I can’t have the test because of my bg. Does anybody know how I should handle this? I have had colonoscopies before but not since my diagnosis and I am really scared.
Thank you so much in advance for any advice you may be able to give me.
