Why do I have to test my blood sugar?

Hi all,

I just got diagnosed with type 2 diabetes, and they put me in metformin. My question is, why do I have to test my blood sugar so often if I’m not on insulin? I’m not adverse to it, I’m just wondering if there is something I should be looking out for. My doctor said my blood sugar probably won’t get above 250, and not to worry if it did, I won’t need to do anything, and she says it probably won’t go too low either, so I’m wondering why I’m doing it if I won’t be doing anything based on the data anyway. I think I missed something in my appointment.

Thanks for all your help!
