When I first found out I had CFRD i was in the hospital because I had gotten another lung infection. At a previous visit they had tested my A1c level, and it was abnormaly high. So they thought it was either CFRD or i was experiencing high blood sugars because of my health at the time. Throughout the next year they kept checking my A1c, and eventually check my blood sugars pre and post meal to see if i had CFRD. It really made me angry that i had another disease to deal with, so i kinda didnt take care of it for a while, and i eventually ended up in the hospital again. They taught me all the ins and outs of CFRD, and I wasnt so scared of it any more. If not taken care of, CFRD will most likely land you back in the hospital every time because bacteria multiply better when there is a high glucose level.
For me I take both Humolog and Lantus, The Humalog to take care of meals, and the Lantus every night. (It is a long term insulin to make things easier throughout the day) Both of my insulins are in a disposable pen, so i just carry them in my pocket along with some needles made for the pens. Once I am done with both of them I can just toss them. They dont really effect me as much as I had imagined, I just have to cound how many carbs I take in, and calculate the ammount of insuline I need to take. Its really not that hard to do either of these.
There is no cure for CFRD so far. I would think if your doctor sees a trend of exaserbations, he will have a A1c blood test done, to calculate your glucose average level over the last few months. If it is high your doctor will probably ask you to monitor your blood sugar levels for a while in order to determine whether or not you have CFRD. I have heard of people with a mild case of it just taking pills to control the symptoms, but i dont know all that much about it?
Hopefuly I was helpful!
