My morning fasting blood sugar 6.8, may be diabetes

Fasting blood sugar in the morning should be 3.8 to 6.1 millimoles per liter. Your test shows that it is 6.8 higher than normal, but it has not yet reached the standard for diabetes. It may be caused by shock, and it is not necessarily diabetes. You can improve your diet. Repeat the test in a week to make a diagnosis.
