    Hi I’m a type2 diabetic.. on a low carb diet 98% of the time. Using a freestyle libre glucose monitor & fingerpick testing.

    I started 500mg metformin on Friday evening.
    My glucose levels are higher at night and in the morning since starting it.

    Even just eating eggs & bacon I’m getting a spike on the Libre, my glucose levels are not coming down as far as normal..

    Morning glucose is 7-8 mmol by 10am I’m usually a 5.5

    Now morning is 8-9 and I’m still up at 7 at 10am ..
    Sunday I didn’t get down to 5.5 until 3pm ..

    I’ve checked these readings against fingerpick tests too.

    So just wondering if metformin in the 1st few days/ week can cause the body to pump out extra glucose, causing an increase in glucose levels?
