side note: I have wondered since the extra glucose messes up the red blood cells, I wonder if it affects how oxygen, and how much of it, is carried through the blood stream (since it is also carried by the hemoglobin) which is kind of an issue for some of us cystics with messed up lungs.  I’m going to look more into that someday. But if I find that is true I am going to get even more pissed at the CF docs who put off CFRD testing (not mine luckily). *sigh*

Apparently a “normal” person would have an A1c level at about 5.0%.  My doctors suggest an A1c of 6.5% or a little lower, normal would be ideal, but that is darned hard to reach.  My docs find that above 6.5% it seems to really affect the CF lungs.  To me I really couldn’t understand what that number meant until I found a calculator online that could translate the number into something I was familiar seeing on my little meter tester thingy I use every day.  Here’s one I like, it goes both ways from A1c% to mg/dl.

Here’s a little chart on dLife:

154 mg/dl is the magic average number.  Personally, what I try to do is make sure I am at a safe, but lower number (preferably 85-95) through out the night since I am spending 8-9 hours at that level.  Recently with my Continuous Monitor I have found I am having a strange spike at 2:30-3am which means I am going to need to change my basal insulin rate at that time… but that is a whole different story.

Once last year I scored a 6.0% on my A1c test (yes, it went on the refrigerator)… I really doubt I am there again, it took a lot of hard work and discipline, but here is some tricks of how I did it…  Having a lower level for many hours while I am asleep made it easier to get to my goal A1c level.  When I spike at meals, I try to keep it under 200 mg/dl at the two hour mark by counting my carb intake as close as I can (IMPOSSIBLE when on evil evil prednisone), but I make corrections at the 2 hour mark if I have to (my pump figures out the calculation taking in consideration how much active insulin I already have in my system, which is why I am such an advocate of the pump, it does all the brainpower).  I have played with my numbers and found at my of 1 unit of insulin (which is an unbelievably small amount, it’s like a few drops!) for every 8 grams of carbs and my correction or sensitivity rate of 1 unit to 25 mg/dl (how much my bg number will drop with one unit of insulin), If I miss calculate my carb intake by 20 (two macroon cookies, who ever eats just two cookies?!) my blood sugar level will go up 62.5 points (mg/dl). HOLY!  That means I need to keep quite a close eye on things.  It never used to be that way when I was on shots, I was on a 1:15 ratio…. but then again, I was never in control of things on shots.

Back when I was out of control, my A1c level (at least the first one I really paid attention to) was 9.3%.  That number alone wasn’t enough to scare me.  But it should have.  The toll it took on my poor body was too much for it to handle and I have not escaped a few complications.  Nothing too scary, but annoying enough to get put on a few extra medications.  I wish I would have known then what I know now.

Diabetic ketoacidosis (DKA) is rare. (I would love some more info on this).

Pancreatic insufficiency associated with CFRD.

A1c levels may underestimate abnormal glucose metabolism. (would love more info on this too). So far I have only found that there is an increased red cell turnover, causing a “diluted” A1c level.

The A1c level can show the average blood glucose levels over the past 2-3 months. A decent indicator of how well of control the diabetic has over their blood sugar levels.
