I was diagnosed with Type 2 diabetes 2 years ago, after my heart attack. I have not had any true medical instruction or what to watch for, how to manage (except, of course, my Metformin meds), no formal information. I have the Contour Next EZ monitor and my numbers are typically between 4.8 and as high as 9 (with reason.) I'm not even sure what numbers I should be trying to stay within. I noticed that other monitors have a different measurement? Mine will say 5.2 mmol over MM and I don't understand this. Can anyone offer information?
