wierd blood sugar readings

I hope someone out there can give me an answer...... my blood sugar reading are usually high and I don't wanna take the meds just yet because I believe that I can lowered them down myself. but this is the weird part, like I said i'm use to having my blood reading high like in the 200's. BUT, once in a blue moon, my reading drop down to close to normal reading and no matter what I eat, and it could be like cake and soda or both together, my sugar reading does NOT go sky rocket. if anything it goes up like maybe 5-7 points. For an example, the other day I checked my blood and it was 140, mind you i'm use to it being 240, well anyways it was 140, I then went to the mall with my kids only walked a little bit not much and then ate a very sweet cinnamon bun and a sprite.. now normally that would of shot up my sugar way up, but I checked my sugar like 90 mins later and my blood reading was only 146. hmmm why? I am a type 2. does my sugar reading go back to being normal out of the blue and then go back to being high? i'm so confused! ive told my dr. about it but he has no answers.

walked a little bit not much and then ate a very sweet cinnamon bun

Exercise (walking) is good for controlling blood sugar. Cinnamon is famous for controlling blood sugar. IMO you should watch your diet (no sweets especially soda, but cinnamon without the sugar is OK) and get more exercise. Otherwise sooner or later your blood sugar will eventually explode up and it would be much harder to bring back down.

I agree with LanieG that long term high blood sugar is damaging your health. Think of it as acid running through your blood vessels damaging your internal organs. You must get it under control.

If you can now control your diabetes with diet, exercise, and a milder med such as metformin then you will be much better off than waiting until everything hits the fan.
