Confused and in need of some advice

Hi - I have just been diagnosed (last Friday) as diabetic but am slightly confused with my glucose results. I'm afraid that when my GP told me, I went into shock mode and didn't quite take in what he was saying. Anyhow, I have an appointment to see the Nurse at my surgery in 2 weeks time where, I have been told by my GP that she will explain everything but I wanted to double check my bloods so asked for a copy, which came in the post today and this is where I get confused. I had a glucose test where you fast, have blood taken, drink a sugery drink then more blood taken 2 hours later. The results were 4.8 mmo/L and after the drink 12.4 mmo/L. From what I understand from this forum, the first result is good and I'm not diabetic but looking at the second result it seems that I am. The only other test results I can quote is my HbA1c taken in April of 6.4%. I have lost nearly 2 stone since March and have cut out sugar, chocolate, sweets, cakes etc and am eating a much healthier diet.

I am still trying to get my head around everything but realise, from all the knowledged gained from this forum, that self testing is the most proactive thing I can do to keep a check on everything. Whether the nurse will run with that idea is another thing, but I will cross that bridge when I come to it.

Sorry for waffling
