The risk assessment you talk about is an assessment of your estimated risk of heart disease or stroke within the next 10 years. Your age, gender, diabetes status, blood pressure, cholesterol, weight and height are entered in to a calculator, along with information about close family history of heart/stroke issues, and some other diseases you may have such as arthritis. The calculator comes up with a score advising you of your percentage risk of cardio vascular disease in the the next 10 years. It is called the Q-risk. You can do it yourself on-line if you feel so inclined.

You should be assigned a nurse who will put you on the diabetes care pathway (or at least she should do). This involves referring you for a course and for annual retinal eye screening. She should also do a check of your feet for pulse and sensitivity once a year. You should be called back for another round of blood tests in 3 months time and a review of how things stand at that time. She should also give you advice on diet, but most likely this can be taken with a large pinch of salt because the NHS is way behind current science on which foods are good and bad for type 2 diabetics. You will get better advice on here.
What you should do is ask for a print out of your blood test results. You can then study them at leisure, look things up, ask questions on here, and take it from there. Never accept any verbal comments such as "you are fine". You need to know how fine.
You should also buy yourself a blood glucose meter and test strips. You will need this if you are to discover which foods your body can tolerate. When looking for a meter be careful to check the price of replacement test strips. Some brands are very expensive. Meters are often given away for free, but the strips will certainly not be free and you will need a lot initially. Many of us on here use the Codefree meter because it has the cheapest strips.

Good luck, and do ask questions.
