Hi. There is only one answer and that is to take control and test. You may not need to test very often but you must test occasionally to check what foods are affecting you and whether your blood sugar is drifting upwards. The reason the NHS does not support T2s testing is due to the cost of test strips.
Good pragmatic reply, there are politics involved, business and costings, i.e. "not need to test very often but occasionally", seems the order of the day. It depends on individuals situation end of day, but it is not so black and white as I see it.
Non Diabetes normal ones blood sugar goes up and down daily.
Daily testing
Pre diabetics, Diabetes D2 if testing, good positive, allows one to see how foods affect the sugars and other. Results may affect oe in different ways, may give depression as not happy with the result, worried, re the result number, re test, and see that even without certain foods, may same or more, or less, ones day is constantly on edge, what will my test reveal, what will it show, Will I be over, low, high, anxious. It can be good and also not so good as stress tension, can surely affect what could be a happy normal day.
Test Occasionally
Can give good positive also. I speak from own experience as only test every three months. I do this for a reason, I know non diabetics in the world sugar goes up and down or so the professional meds inform, anyway, so I choose by personal choice to test myself this way.
Test same day, same time every three months. i.e. Fasting 7am normal and if intermittent fasting x 24 hours test 6pm evenings. 2h after eat 4pm. Random 12noon and 6pm
Results. Amazing actually. During the three month period, my levels are more or less the same each time, yes there may be one or two points more i.e. fasting may be 96mg/dl previously compared to 94mg/dl or 2hr after eat 89mg/dl or 91mg/dl, random 98mg/dl or 94mg.dl as examples.
What does this tell me, that even not testing daily, and only every 3 months, I feel gives better knowledge and guide, how overall during a 12 week period of eating, daily life, shows indicates, if the levels were vastly different, then I would probably test slightly more often say each month, I feel results been more or less the same, speaks volumes overall.
Its entirely a personal situation of control and how wants to do it daily once or twice or many more times, and or monthly or as myself only 3 monthly for example.
the method I choose gives peace of mind during the three months, as long as I keep up my control regime, keto, exercising the same, intermittent fasting, skipping bread, potatoes, pasta rice, personally for my own body, I do not feel I can do any better than this anyway at the end of the day.
Ones situation may warrant daily testing, and if that's the case, it would be a must situation.
Another piece of info for the pot. In Spain doctors say Ignore testing of finger pricks, not necessary, they even now say ignore the "average BG" shown on an A1C, I agree to disagree on this to be frankly honest, and for this ignore same, and continue testing 3 monthly periods.
