Hello,
from your results, you may be having early thyroid problem. The T4 is low.
Ideally your doctor would conduct antibody testing. You should have your thyroid monitored regularly now (I would recommend every 6 months), and testing should include TSH, FT3, FT4.
Your HBa1c is on the high side (though not enough to get you diagnosed as diabetic) - if you compare it to truely normal a1c, which should be in the low to mid 4s. If your doctor were proactive he would order a glucose tolerance test. This may develop into overt diabetes with time.
Are you overweight / normal weight? Are you phsyically active? Do you have any family history of diabetes (type 1 or type 2). Was this feeling of being unwell triggered by any event? An illness? Vaccinations? Period of particular stress?
For the meantime, please focus on eating a lower carb diet (no softdrinks, fruit juices, limit rice, bread, pasta, etc), and exercising regularly. I would be treating myself as if I had diabetes already (in terms of diet and exercise with this A1c).
I do beleive this is something that should be watched closely.
Hope you feel better soon.
Sorry for your troubles
As far as diabetes goes, your A1c is on the high side of NORMAL (wish my A1c was that low)
I cant help with the rest.
You might ask for a GTT test (glucose tolerance test) Wide swings in BG can be tough on you and you can still still have a low A1c because you go High and Low bg so it averages out (A1c) is a test for average BG
