All good advice above. If your Dr has not told you your HbA1c, you might be able to see what it was if you use any of the NHS apps, I use Patient Access. If you log into the app it usually shows you any recent test results.
Sorry, should have also said welcome!
When you are first diagnosed it is a bit of a shock and can be a lot to take in, but as above, knowledge is power.
Many people can manage their diabetes effectivley with diet, and usual advice (for T2's) is to go low carb. That means ALL carbs, not just sugars, so potato, rice, pasta, baked goods, sweets, cake, etc, etc.
Be careful with fruit, as many think its ok, but for diabetics many fruits are high in sugar/carbs, so need to be avoided, eg: bananas, exotic fruits, etc. Same with veg, many veg are high in carbs, eg@ potato, parsnip, sweet potato, most below ground root veg, etc, so best to stick to above ground green leafy veg, salads, etc.
Good news is you can lots of meat, fish, poultry, etc (assuming not a veggie/vegan!)
Check out the learning zone on here, and also check out the lowcarbfreshwell website and the sugarfreelondoner website for lots of good diabetes friendly recipes.
Good luck with it all and let us know how you get on....
