Hi VickyRenee!

While a fasting blood sugar of 118 is a bit high, I don't think it's anything to panic over. Many things can affect your fasting blood sugar including how close you are to your TOM, whether or not you are sick and how close to bedtime you ate. If you're truly concerned about it, you may want to schedule a visit with your doctor for some further testing just to put your mind at ease including a HgbA1C (or glycosolated hemoglobin test) that will show what your average blood sugars have been over the past several weeks.




This is a bit soon after eating to test. To truly get an idea of how a food affects you, you need to test at 30 minutes, 1 hour and 2 hours after eating (sometimes longer if the food you ate was very high in fat as this will delay the rise in blood sugar by an hour or sometimes 2). A rise of 30-50 points after eating isn't unusual, depending on what you ate. Yours increased by 20 points in 20 minutes and probably continued to climb for about 30-40 minutes after that although I wouldn't hazard to guess how much more. What you need to look at is how quickly your blood sugar returns to normal levels after eating. For the most part, you would want a return to pre-meal levels or < 120 within 2 hours.




Fasting blood sugar readings can very considerably from one day to the next for a whole lot of reasons which is why it's important to look at the average and overall trend.

The good news here is that low carbing is the best way there is to control blood sugars, so even if there is a problem that you weren't aware of until now, you should be able to control it quite well by continuing with low carb. Imagine how much higher those blood sugars would be if you were eating high amounts of carb!
