So went for an appointment today and have been told they will be putting me on insulin because. One my overall blood test result went up and I've been losing weight...well I've been losing weight because I've been training a lot. I've been jogging to work and working out every night which I told them but they ignored and my blood glucose levels are totally fine. Heck at times they've been to low. Since testing I've never seen a number higher than 8 in my tests and that includes sickness and Christmas, birthdays etc. my problem is if they put me on insulin that could cause me serious problems because even right mow at nights after my training I've been getting readings of 3s and at the very extreme 2. So if I start taking insulin on top of that I'm in trouble. I of course told them exactly this but they dismissed it saying that those readings can be inaccurate and maybe it's higher when I'm not checking it...genuinely don't understand this. I have no symptoms I'm not going to the toilet me I've got loads of energy and feel great.
Gauging by your profile pic, you look very lean. I don't know if this was taken before the weight loss or not, but if you are losing weight (Based on your photo) it doesn't seem like it would be a good idea. It doesn't look like you have much fat to lose, so that more then likely means you are losing muscle mass. If you are type 1 that would make sense, so insulin would be prescribed anyway, regardless.
Maybe I missed it, but what are you are training for exactly? Get fitter, sport? You're jogging to work, in the gym everyday. It just seems like you are way over doing it and running yourself into the ground. So, either your diet doesn't match the training to maintain or you lack insulin and are losing mass because you're type 1. Your body is just breaking down muscle to get the protein it needs. Or it's both.
I just find it unlikely to be a bad HBA1c and it would be pretty unlikely to be a red blood cell issue, but certainly not impossible. The fact you test 4 times a day, leaves a lot of room for highs to go unnoticed. I guess you could ask to have the HBA1c done again, but they probably won't. 7.9 and 8.1 are pretty close together. That's seems reliable to me, or you have some other issue no one knows about that is causing odd levels?
I'd go with what caterpillar said about the libre sensor, this I think would probably sort out your bg level and conflicting HBA1c problem. And find out if you are type 1
Good luck
