Hello All: This is my first post to this forum. My recent lab test showed my fasting glucose level as 83 but my A1c was 5.7, which puts me in the pre-diabetic camp. What do you make of those two seemingly contradictory readings? I've been searching the Web and haven't been able to find much info on both readings together.

I'm 71, normal weight, and try to eat healthy although I love my complex carbs such as beans, nuts, brown rice and whole wheat. I also work out about 4-5 times a week on average.

Your fasting is exactly 'normal'. Your A1c is also fine even if it seems to be only slightly elevated from exactly 'normal'. Your complex carbs are fine and since you are not overweight and you are working out, I don't think you need to worry about your blood sugar unless you see that it's getting higher at every testing.

Red flags would be: family history of diabetes (parents, grandparents, siblings), being overweight, being sedentary, high fasting, higher A1c, diet of too many simple carbs.

What does your doctor tell you?

And welcome to the Diabetes Forum!

Thanks Lanie, just got back from doctor appointment. He wants me to cut back on carbs and do a retest in three months.

The carbs that most people eat are: products/food made of white flour like bread, pasta, crackers, cereal, cookies, cake; potatoes; products/food made with sugar (or honey, maple syrup, brown sugar); rice. And the main problem about all these is that we eat too much, so if it applies to you (doesn't sound like it does though), then you need to cut back on those.

Working out uses up the blood glucose in our system and this is why you'll see runners load up on carbs before races as the carbs give them energy. So, your work-outs are very beneficial to keeping blood sugar in check and even more so if you're eating complex carbs as you wrote in your first post.

I'm glad the doctor wants to do a retest but I'm wondering what he is aiming for. It will be interesting to compare those results with the recent ones obviously.

I wouldn't be too worried if I were you since your fasting and A1c are really good. Do you have any immediate family with diabetes? If so, maybe that's what he's concerned about.

My maternal grandmother and an aunt had type 2, and I have two first cousins with type 2 and another with type 1. But the doctor didn't ask so he doesn't know.

Ah, that's interesting. Then, you need to be watchful that your fasting and A1c do not start rising. Otherwise, it seems to me that you're doing everything right! Doctors normally do the A1c test two or three times a year.

Good luck!

Hi Joey, welcome to the Diabetes Forum. I think the answer to your question would be to change what you're eating.

So, I'm going to make a new thread with your question!
