hi I went back to the gym for the first time after being diagnosed 6 weeks ago I am on gliclazine and metformin I didn't eat before I went as I planned to have my breakfast after it I took my gliclazine before the workout...my morning reading was 6.7 but after my hour workout. It went up to 8.8 is that normal for my sugars to go up after a workout thanks for any help
