Hi SH, welcome to the Diabetes Forum. No, 108 is not really high for a fasting reading. Doctors are looking for under 100. A "normal" person (someone who is not diabetic or having trouble metabolizing carbs) would be in the 80's usually. There are always extenuating circumstances though that can throw the fasting off: eating a large dinner with a lot of carbs later at night maybe and being close to diabetic. Stress can also cause high blood sugar levels, so the hospital experience could do that. There is evidence that people who are hypoglycemic when they're younger may turn diabetic years later. In any case, you are wise to monitor your blood sugar now so it doesn't get out of hand. Normally, you would test when you wake up (fasting) and 2 hours after a meal. You'll find descrepancies as to what a 'normal' reading should be after a meal. If you eat a very big meal and have lots of starches (bread, potatoes, rice, pasta, dessert...), then you would expect that your 2-hour or "post-prandial" reading would be higher than you want. Even a non-diabetic might spike up to 140 or 160 after a carb-laden meal but would quickly recover. A diabetic or someone who's controlling diabetes with diet (like me) would take a much longer time for the blood sugar to come down. Blood sugar over 140 or 150 for a long time, hours, can damage internal organs over time, so it's in your best interest to keep the blood sugar lower. As far as the nurse's reaction, maybe she was just expecting a normal reading, but I think you should be aware that you may indeed have some preliminary warnings of diabetes in the future if you don't pay attention now, so in a way, it's good that it got your attention. A family history of diabetes, carrying around extra weight, carb-rich diet with no regular exercise can accelerate anyone toward the disease, so the sooner you are aware of this, the better!
Thank you for your reply Lanie.
I don't have any history of diabetes in my family. I do suspect that my sister is hypoglycemic but she has not been tested but has all the symptoms that brought me to the dr to get the gtt done in the first place.
To be honest, I have not been diligent about my diet to control the hypoglcemia over the past few years...mainly because of stress...and then I would stress eat. When I was dx with hypoglycemia in 2001 I watched what I ate and basically cut out all carbs and I felt so much better...basically went on the Atkins Diet...but for me it was a way of life to control my blood sugar levels so I didn't consider it a diet...but I have been lax over the past few years. I was never a stress eater but for some reason I am now...but that has to stop now.
My blood sugar after eating for the past couple days has been right around 100...flucuating a few points here and there. When I was testing myself regularly and watching my diet it was normally in the high 80's...so I am a little concerned...but hopefully this is nothing I can't control with diet.
The nurse did scare me...which may be a good thing because it promted me to get a glucose meter again. Mine broke a year ago and I never bought another one.
Can stress really cause blood sugar levels to increase? I have been under a tremendous amount of stress...so much so that I was put on anti anxiety meds.
Yes, stress can affect blood sugar causing it to rise. Same with illness. If you're physically sick, your blood sugar could also rise, so we're in a fix sometimes! The stress of losing your husband, dealing with kids, all that can have effects on the blood sugar. You are aware of these now and you know that carbs can drive blood sugar very high, so you're half way there to controlling it. The other half is eating right in order to keep the blood sugar in control also - and from what you've written, I'll bet you'll do fine! If you are taking any medications for any other conditions, also know that some can affect the readings, so check out the package inserts, ask the pharmacist and/or google for info online just to be sure. You don't have to test a lot, just to see how your blood sugar range is and if you have highs, then what is causing them.
