I'm a newly diagnosed type 2, having been diagnosed with a HbA1c of 50, now on one Metformin twice a day. I really had no advice from my doctors surgery but gathered I have to lower my intake of foods which make my blood sugar spike, like sugar and white carbs. I'm doing that and now have a Libre monitor so I can see what other things make my blood sugar go rushing up. Can somebody tell me whether it is OK for my blood sugar to go up from, say, 5.2mmol to 10 straight after a meal if it is down again to around the 5 mark within 2 hours. Is 10 a worry or can it go higher without a problem? What's the max it can go to? And then is it good to come down fast or slowly? Is it fine if it's back to normal within 2 hours or should it come down faster than that? What should I be aiming for?
