Hi Pauline,
I agree that we type 2's have to be very lucky to get a meter and strips prescribed by our GP's. Do buy your own. They are the best way to learn which foods you personally can or can't cope with. Once you get one, we will explain how best to use it. If your nurse says don't test, please ignore her.
With an HbA1c of 52 there is usually no need for medication initially. Your nurse will be giving you 3 months to try diet and exercise, and if successful you may be able to avoid meds altogether. 52 isn't at all drastic, so with a changed diet you should be able to get it down even further.
As for diet, it is important to know that carbohydrates turn to sugar once inside the system - all of them, not just the obvious ones. The worst culprits are potatoes, rice, pasta and bread. We also need to be careful with milk and fruit as both contain a lot of sugar. (whole milk is marginally better than skimmed or semi skim). From a diabetic point of view, there is no need to be afraid of good fats like butter, yogurts, cheese, cream, olive or rapeseed oil etc. Fats do not raise blood sugar levels, but all carbs do. (some more than others) Look at all the food nutrition labels on everything you buy, and look for the "total carbohydrate" amounts. The fewer the better. Ignore the "of which sugars" amount.
