The most effective way to reduce your HbA1c is to keep a record of what you eat, how much you had and when you had it. Then compare your Dexcom results with your food diary, it will become clear which foods are causing you problems. (it will be carbohydrates in one of their many forms) The aim is to avoid any spikes if possible and to see our levels return to pre meal values within a reasonable time (2hrs) usually we give ourselves a bit of leeway and consider a meal OK if our level is no more than 2mmol higher. Anything over 2mmol and we will rethink that meal, reduce the carbs or strike it off our list of suitable meals. I would imagine that they do but  they don't have a problem dealing with spikes like we do. "Spike a little" is a very ambiguous term, what you might consider a little spike I could think is a whopper. A rise of a few mmol after eating is just normal, not a spike. So if a pre meal level of say 5 rises to 8 and is back to around 5 within 2hrs the carbs in that meal have been dealt with fairly well. If on the other hand it rises to something like 10 and at 2hrs is still at 7-8 , then I would not consider that acceptable.But we're talking about you not me, so you have to make your own decisions about what is acceptable to you and how quickly you want to get that hba1c down</blockquote>
