Fasting blood glucose question

I got my fasting blood glucose results today and would love some perspective on interpreting them...

So I scored 95, where normal is 70-99, pre-diabetes is 100-125, diabetes is 126+.

95 seems to me to be on the higher end of normal. Here's my situation - I've never been diagnosed w diabetes, though it runs in family. Several months ago I adopted lower-glycemic diet for weight-management, whereupon I noticed that anytime I slipped and did what used to be a normal amount of carbs for me, my energy became sluggish. I already knew that more than a small amount of sugar made me speedy - I'd tend to do 1/3 slice of cake at parties even before the more comprehensive dietary switch.

So my question is basically - how much does fasting blood glucose level shift via significant dietary modification (or other factors)? Should I assume that if I wasn't on the low-gly diet, my numbers might be in the pre-diabetic range at this point? Or should I assume that 95 has been and will be my general lifetime fasting blood glucose level?

Still new to how all this works, as you can see! Thanks...

Every blood cell that your body creates lives for three months. Say you eat three candy bars a meal three times a day for a week. Even if you eat nothing but salad the next week, you will still have those blood cells that were created with too much sugar for three whole months.

If you eat a healthy diet that is low in simple carbohydrates and avoid sweets, but one evening eat a huge bowl of pasta, you will probably feel sluggish and crappy for the next 36 hours while your body processes it. While the blood cells that were created that day will have a higher long-term glucose level, eating healthfully before and after can keep your overall 3 month glucose level low.

What this means is, if you avoid simple carbs for 3 months and then go and get re-checked, your numbers should be lower.

The thing about diabetes type 2 is that with a proper diet, you can make it disappear. It's all about managing your food intake, getting the proper ratios of carb/protein/fat as well as eating enough during the day (which is HARD to do!). Generally, you should eat every 3 hours, and no more than 4 hours apart. If you eat 1/4 carb, 1/4 protein, 1/2 veggies with around 60g of fat a day, and make that into 2 of 3 medium meals with 2 or 3 light snacks, you should be able to get a really great fasting glucose number at the end of three months. If you are 'borderline' now (which you are not quite), eating like this may serve to drastically reduce the risk of developing adult onset diabetes.

Do not assume that 95 is your all of the time number. I suggest you get checked every 4 months for the first year while you are experimenting with your diet, and ask your doctor about diabetes and your risk factors.

I'm sorry this got so long-- I'm kind of tired. Please feel free to ask me any questions you might have. I've been doing this diabetes thing for a loooong time.

Thank you so much! This is very helpful. I really appreciate you taking the time to write.

Per my dr, 95 is a good number. You don't want to drop too low any more than too high. Mine is reliably 95-100 due to a low-carb diet; without the low carb diet I feel much worse and my blood sugar control goes out the window. With it my blood sugar control is good (A1C=5.2)

I can add in a bit more carbs now after several years of good blood sugar control, but I do still need to avoid concentrated sugars and balance increased carbs with increased protein and fat.

Has your A1C (glycohemoglobin) been tested as well? That gives you a picture of your blood sugar level over several months, rather than the snapshot of a single moment that blood glucose testing gives.

If it were me, I would assume that the 95 is due to diet, and would *not* assume it will stay there if go back to a standard american diet.

Yes, diet, exercise, de-stressing all help lower blood sugar - not just immediately, but also in the longer term by improving glucose metabolism - so probably, it would have been higher without.
As Rainbow says, the A1C would be really helpful. While you're at it, you may also want to request a couple of other tests:
* Vitamin D. Low levels run in families, are a lot more common than they thought, and recently have been implicated in diabetes, cancer, memory problems, thyroid problems, mood disorders ... not just for bone density, after all.
* Vitamin B12. Low levels run in families, are common in diabetics, are associated with vastly increased odds of nerve problemsand circulatory problems, but are cheap and easy to treat IF detected.
Best of luck. Sounds as if you're on the right track. :-)
