My sister who is now 51 was recently dx with type 1 D I was told it can happen but is rare. Well she wants me to go in to get tested she told me there is a blood test that can tell if I am at risk for developing type 1 as well.. So, before I go to see my doctor to ask to be tested what test should I ask to be given? Now I have hypoglycemia and have had it since I was a kid, and I test my glucose often, especially when I feel low, which is about 30-60 minutes after eating anything and I am usually between 65-55 The past month I have noticed a change, my morning number used to be between 80-110 now it is running between 115-150, I tested 2 hours after dinner last night and I was 198 and feeling like crap, headache, hot, just plain nasty, irritable as all get out.. I drank tons of water and after 30 minutes went down to 150. This morning I was 189..So something may be going on..I also had trace ketones..My 14 year old was dx @ 10 and I know the symptoms when he has them, but now I am more aware of how he really feels when he is high or low.
