Dear lmshull

Thank you for writing dLIfe and congratulations on your weight loss!

According to the American Diabetes Association an A1C of 6.5 or higher on two separate occasions constitutes a diagnosis of diabetes.

There are several reasons for a discrepancy in your blood glucose readings and the results of your A1C. You have very limited information when check blood glucose only one time daily. Remember, the results of your A1C, are representative of what your blood glucose is running 24 hours a day, for the previous 3 months.

Meter inaccuracy is another reason for discrepancies. You can learn more about quality control of your meter by clicking here.

You mention that over the past 2 months your diet has been primarily vegan - eating fruits and vegetables. Beans, fruits and vegetables - the main components of a vegan diet, are all sources of carbohydrate. Eating too much carbohydrate at a meal can cause your blood glucose levels to run high after the meal. Tracking and recording your food intake and blood glucose levels, is a good way to determine if your blood glucose is high after meals.

Here's an easy way...

For three consecutive days, check your blood glucose before breakfast and again two hours after breakfast. Then the next three days, check before lunch and again two hours after lunch. Finally, the next three days, check before dinner and again two hours after dinner.

Keeping track of your blood glucose - and making note of your activity and food choices - particularly grams of carbohydrate, can help you identify how they affect your glucose levels. Once you complete the record, you may be surprised to find, that at times your blood glucose is higher than your target. If that's the case you may need to eat smaller portions or less carbohydrate at meals.

Good Luck!
