I think I can answer my own question here; that answer being no, but I just want to see what other people think. Of course it's normal to have a spike in blood sugar 2 hours after a meal; that's what happens to normal people. I'm just wondering if it's dangerous / unhealthy in any way to see no increase after a meal, possibly due to Metformin in my case. I did a pre-meal test last night and I was about 6 mmol. I ate 100 grams of bran flakes, with 15 grams of sultanas thrown in, 200ml semi-skimmed milk, and about 170 grams of cold chicken. I work that out to be about 34 grams of sugar. (Must be over 80g of total carbs). I also took my 2nd gram of Metformin for the day. 2 hours later I do my next test and I get 4.4 mmol. Test again to be sure, and get 4.7 mmol. So it was like that meal never even happened, and the blood sugar just kept decreasing from the 6 mmol I started at pre-meal. So... healthy? Unhealthy? Of no consequence? Should I be eating more to ensure a normal spike..?
