My glucose levels are currently between 196 to 257 in the last week. should i call my doctor?

Call: If you have been having very normal sugars and suddenly they increase it is important to look for a cause. Often this is a precursor to an infection in the body somewhere or another increase in stress on the body. Certainly eating habits can cause this to change suddenly as well.

Yes.: You should keep a log of your daily blood sugars and discuss with your doctor about optimizing your medication regimen.

Poor Control: If these levels are fasting, they are signs of poor control. Not necessarily critical. You may require dietary or medication changes to improved your blood glucose control
