From what I can gather reading posts from the luckier type 2's that are given meters and strips on prescription, many (most) seem to be told to test once or twice a day, or a few times a week, maybe just morning fasting and before dinner (no mention of before dinner + after dinner).
It seems to me the nurses/doctors have not grasped the importance of newly diagnosed testing out their reactions to foods (before and after each meal). They seem to think that just keeping an eye on general levels occasionally is sufficient. When I told my nurse I had learnt how to restrict my carbs portion-wise by testing each meal she looked genuinely amazed - this had never occurred to her as a possibility.
I point "they" made against testing was, "What will you do with your BG readings - you can't make spot adjustments to your medication." That, of course, applies to occasional spot tests, which with well controlled T2 will stil range from 4 to 9.
There are many informed answers for T2s on diet only or tablets, e.g.:
readings above 12 call for adjustment to diet &/or medication
readings 9-12 require adjustment to diet;
readings below 5 require food;
readings between 5 & 8 are OK.
Time of measurement in relation to meals will have a bearing, & only regular testing, before & after meals will give a true picture, & enable satisfactory control.
After, say 1 month's testing 3-6 times a day we get a clear picture & can reduce testing. I always test after overnight fasting, & occasionally up to about 6 times. I don't trouble the Dr apart from 6-monthly blood tests, so presumably my test strips ARE cost effective.
Occasional more frequent measurements are also informative - the DUK recommendation to test 2 hours after a meal allows the spike to reduce. When I tested porridge, the 2 hour reading was 9, but 1 hour was an unacceptable 14. The DUK recommended Fruit & Fibre gave 14 after 1 hour, about 6 after 2 hours, & 4.5 after 3, & I needed elevenses. So much for high carb, low fat being sustaining. I'll keep eating my nut porridge - or bacon & egg which used to be the standard, recommended b'fast.
