I've just been diagnosed as a diabetic on 2 April. At time of diagnosis, fasting glucose levels were pushing 400 pretty hard. A1C was over 11. I had lost about 15-20 lbs from my healthy weight by the time I saw the doctor (I am not overweight normally)
Initially, I assume because of my age (29) the family doctor I saw (I was away from home on an extended business trip) told me it was type 2 and put me on metformin immediately. My first set of labs came back with low insulin levels and low C-peptide-- at that point the doctor changed his diagnosis to type 1 and had me stop the metformin and start a MDI routine with Lantus and Novolog. This has brought my glucose levels into normal ranges, and actually I've had to reduce my insulin doses significantly due to glucose levels trending too low. At this point I'm only taking 8 units of Lantus each day, and 20:1 carb ratio with meals for the novolog. It's my understanding that this is a very small dose for a full grown man.
So up until yesterday I believed I was a newly diagnosed type 1 enjoying the temporary "honeymoon period."
Yesterday some new labs came back for auto-antibodies. These results bewilder me, which I assume if due to my lack of understanding; My GAD autoantibodies were elevated at 3.6. Insulin and islet cell autoantibodies tested negative.
If I am type 1, wouldn't I have islet cell antibodies? Isn't that the whole issue with type 1? My doctor basically says he can't definitively say one type or another at this point, and indicates I might be able to wean myself off the insulin and onto oral meds if my glucose levels stay as stable as they have been lately.
I just don't understand. Does anyone have any wisdom to share?
