I recommend the following intensive testing routine for people newly diagnosed with type 2 diabetes. It can also be very useful for those who have been diagnosed for a while but who feel they have "hit the wall" in their progress towards good control.
For the first couple of days test fasting blood glucose (on waking, before breakfast) and also at one and two hours after absolutely everything you eat, unless you eat again before the second test. That includes breakfast, lunch, dinner and all snacks. This may help if you are not used to testing so much: Painless Pricks
One hour after meals.......under 140
Two hours after meals.....under 120
or for those in the mmol parts of the world:
One hour after meals......Under 8
Two hours after meals....Under 6.5
Give yourself some time. It may take a few weeks, or even a few months, but the investment in strips and testing you make now will pay you dividends for years or decades. Eventually, when you find you can easily hit those targets consider revising them as I did. See my present targets at the foot of Test, Test, Test.
Proceed cautiously if you use insulin or one of the insulin-stimulating medications. You do not want to go from hyperglycemia to hypoglycemia. Make modest adjustments to your carbohydrate intake, test the results and continue modest changes every meal until you achieve your goals. Eventually you may need to discuss reduction of your insulin or medications with your doctor as the numbers improve.
During the second week repeat some of those safe meals. Before your post-meal test try to guess what the result will be. If you can usually predict good results note that menu for future use; you will only need to test after that meal occasionally in future for reassurance. That removes another test from your day.
