You are taking your metformin to prevent either. Both happen to diabetics, but mostly you will find if you are eating the wrong things, you will experience more highs than lows. Metformin has a safety net in it that will not allow *most* people's sugars too get too low.
Snafu, you have to check your blood sugar levels with your glucose monitor to determine whether you are high or low. Anything under 4 is a low, anything over 10 (but I would personally say 8) is a high.
It is a good idea to take a class. This will help you understand diabetes much more. @A DiabetesTeam Member has some good resources for Americans, so I have tagged her, so she can point you in the right direction, especially if you end up not being able to get in a class.
Maybe a switch to red wine. It is said that it helps improve the blood sugars of many diets, but as a man, limited to 2 glasses a day.
both
I have been recently diagnosed officially with t2 diabetes after 3 years of high sugar blood test results I've also got copd so cannot exercise much. I've been started on metformin this week and so far have had bad pains in my tummy and dyhyhorrea . been told by a nurse I don't need to check my levels but see that people on here advocate this am going on a diabetes management course next month xxx
