[QUOTE="Newapothecary, post: 990806, member: 101221"] Metformin works in two ways... it encourages the pancreas to produce Insulin and it blocks the Insulin from being reabsorbed by the pancreas. It can only do this in the presence of food. If you only take your medication and not food, the lactose in the tablets will raise your blood sugar but the Insulin wont be released by the pancreas because it needs food to trigger the release. Hence .... no insulin but plenty of lactose.... result higher blood glucose. I am with you on the BG testing though. Having a high HbA1c is like trying to lock the stable door after the horse has bolted but not knowing which door you need to bolt. Even 3 months of food diaries wouldn't tell you which meal(s) are the problem. We have two diabetics in our house. My son can eat bread (5 seeds stoneground) without affecting his blood glucose but can't eat roasted sweet potatoes. I can eat a plate full of roasted sweet potato but not one slice of bread. So just because a textbook says something is a fact doesn't mean your body wont have his/her say about it too. [/QUOTE]
