Hi Leemalcolm, and don't worry, just about everybody who gets a T2 diabetes diagnosis seems to get told about it and then left until the system catches up with them. What you have not got to loose sight of is that it is a condition that can be managed and a good way to get started is to get your brain around the fundamentals and work from there. So, your reading of 92 is presumably a HBA1C - it's a measure of your average blood glucose over the last 2-3 months. Thats one measure. A second measure is a spot test done on a drop of blood from a finger prick. Would not be surprised if your DN (diabetic nurse) does one when you see her. At a HBA1C of 92 that will probably be quite high and between you and the DN you will sort out a plan to get it down because running on high blood glucoses for a prolonged period will start to damage parts of your system and that is not a good thing.
There are two approaches to getting blood glucose levels down. First is medication and standard things to try are something called metformin and something else called gliclazide. You start on low doses and build them up and see what happens. You may be given a blood glucose meter so that you can track the effects. The second approach is to look at what you eat. Fundamentally, blood glucose comes from the digestion of carbohydrates in food. If you reduce the carbohydrate intake, you make less glucose which leads to less glucose in the blood. Cutting carbohydrates has the extra plus in that it can be used as the basis of a diet designed to loose weight. There is a school of thought which says that for a lot of people with type 2, the problem is due to fat accumulation in the pancreas and if you loose the fat, the pancreas recovers and starts to produce enough insulin to control the blood glucose. So, losing weight is a good thing.
The idea that you can eat everything that you have seen is probably advice relating to type 1 diabetes where you inject insulin and the amount you inject is related to what you eat.
That's a bit of a start, I'm sure others will be along to add things.
By the way, I was in your position at the end of December ( HBA1C 82, spot readings around 20) and knowing nothing and reading posts on this forum and asking questions got me up to speed very quickly. Blood glucoze now at more acceptable levels although fine control still needs a bit of work!
