My fasting blood sugar checked daily is in 140s but my after meal and random numbers are all normal. My last a1c was 6.4. why high fasting?

Need for glucose: Tolerance test. Repeat fasting glucose of 140 is considered diagnostic of diabetes. A1c is not a sensitive marker for diabetes. If you have doubts, you may get a glucose tolerance test, however, it would be prudent to alter your diet and life style in keeping a diagnosis of diabetes mellitus. Exercising and losing about 10% of body weight may stabilize the disease. Consult this site for info:
