My endocrinologist said that the prep work may make my sodium levels too low. This is because, as you know, I have to take my medicine to absorb any liquid. So when you prepare the colonoscopy you need to drink a lot of liquid. My endocrinologist is concerned that my kidneys will work to absorb this liquid and therefore lower the serum sodium to dangerous levels.

He wants me to be admitted into a hospital so that they can monitor my urine output so that I can match the liquid I drink to the amount that I pee out.

Has anyone with CDI had a colonoscopy? If you have had one, what prep did you do so that your electrolytes remained balanced?

Thanks so much for your help.
