I wanted to go exercise after lunch, so I checked my blood sugar before lunch and it was 79. I ate lunch and checked it a little after and it was 78. My lunch consisted of a chicken sandwich and fries and diet drink. Not sure why it didn't go up.
So, I sat there for a while and checked a little later and it was only 97. So, I decided to have another snack because I was worried with my blood sugar that low that I would end up on the floor of the gym with a low blood sugar. So, I ate a snack and ran. Now, two hours after all that (3.5 mile jog) my blood sugar is up to 234.
I'm just wondering why I didn't initially go up and if I should have just waited longer. There was at least 45 minutes between eating and checking.
In the past, exercise has caused me to drop blood sugar numbers by sometimes as much as 90 points.
Um, sandwich = bread w/Mayo? French fries fried in oil? The fats most likely delayed your spike, 45 minutes isn't long enough to see the result of that lunch for most people. And then adding more carbs on top of it as a snack. I'm surprised you weren't higher! The exercise probably did bring it down some.
Just curious, why are you eating bread and potatoes?
Granted, I usually bring my lunch and it is very different from what I described. But, I was in a hurry and wanted to get the run in since I am getting ready for a 10k. I didn't realize that fats could delay a spike like that. I have a lot to learn.
Depending on the toxin, oops, carb, as well as the individual, there will be different times to break down and absorb the them. Carbs from some sources, i.e., pastas, may take 3-4 hours to see how high it spikes your BG. Skittles may be 30 minutes. You probably tested too soon.
Dropping 90 points may mean you are going too high to give that much room to drop. Reducing the high, should reduce the drop. I would avoid the bread, the fries, and maybe even the chicken if crusted and not grilled. Some diet drinks affect some people's BG readings too.
Its called a liver dump. Since you had a long and hard workout, the liver dumped sugar into your blood stream to feed the muscles. You should have checked your sugar before working out, during working out and 1 hour after working out. You will notice the big drop in BG after an hour and half. I have the same thing happen to me every time I play 2 hours of basketball. Pre work out my sugar is 97 during workout my sugar spikes to 200+. Hour and a half after workout it drops to 85.
I have noticed though, biking for me does not make my sugar jump at all. It stays constant if not gets a little lower as time progresses.
Hope all goes well... and BTW 86 - 97 BG is not bad at all. Its actually where you want your range to be.... Even if the doctor tells you otherwise. Being diabetic doesnt mean you have to have your BG in the 100's or 200's. It just means you can process carbs properly.
