Hi, since being diagnosed just over 2 years ago as Type Two,my BG levels have been controlled well at about 5 - 6.8 fasting, measured daily. Over the last 2 -3 weeks, however daily measurements rising to 8 -9. I have not really changed my eating habits although I have gained some weight over the last few months. Current medication Metformin X 3 Daily 500mgs. Any suggestions why my levels should be rising after 2 years of good control?
