Id wake up in the morning, my blood sugar was never lower then 158. I started a few days ago trying a different meal plan thx to Jayabee52 and debcox. I combined their meal plan together . I wake up now it runs 119 to 128 which to me is doing better. Well anyhow I get up take my blood sugar say it says128. I walk one mile on treadmill takes me about 20 minutes. I then take blood sugar and its up at least 10 from before I exercised.

Howdy Deb
As Iron suggested that is well within the tolerances of your meter, so what you may be seeing is an artifact of that.

However BG (blood glucose) can go up if one exercises very hard due to the stress hormones which kick in when one is in a virtual fight or flight mode. So, yes if you are doing exercise which raises one's heart rate to at least 90% of maximum the stress chemicals come and with it comes higher BG levels.

So unless you are doing extreme exercise, Iron's suggestion seems the best one.

God's best to you

no need to worry about your BS being up by 10 because that is within the tolerance of the meter, in other words it could have gone up none at all

Deb, I don't know why it would be up after exercising but I think that you have to look at the long term effects of exercising. When I found out that I had diabetes in May, my A1C was 14. I started riding my bike and doing my workout besides watching my carbs and when they tested my A1C two months later, it was at 9.

I started a food journal two weeks after starting my insulin. I put in it the date, my blood sugar levels three times a day, everything that goes in my mouth (and the carbs for it/I total each meal to insure that I don't go above 70), my exercise and my total carbs for the day. I use a college composition book that I got from Staples. If my blood sugar is high, I put an astrik by it and try to figure out why. If I go out to eat, I put down where I ate. This is probably seems anal to some but it has really helped me figure out what foods are good for me and which are not. Also, if I eat dinner after 8pm, I can count on a morning blood sugar level of 100 - 120. I can eat two small squares of chocolate without it affecting me but not four.

I never put negative comments in my journal because it is a learning tool. I do put in comments such as "only eat 1/2 cup of ice cream, Debbie, that is enough to satisfy."

I just went for a thyroid lab test and they will be lowering my thyroid next week because I'm taking meds for someone almost 50 lbs more than I am now. I am keeping track of blood pressure as of tomorrow because they said they will have to lower those meds soon. My next A1C test is on my anniversary at the end of September and should be significantly lower.

Keep up the good work, you can do it!!!

I too try and write everything down and go back and try to figure it out. Yeah why is it if I eat before bed my sugar levels are better in the morning then if I don't eat anything . I've tried both. I mean all I am eating is a few nuts. Course my body is so used to eating anything it can get a ahold of. It probably makes more insulin when I don't eat something small. I am sure i'll get it after awhile. But I am so thankful for you and everyone else here for figuring it out together! : O )

I just had that post earlier. I noticed that since my muscles are getting used to the activity. That my normal fasting was 90s -105. After work out it shoots up to 120s range. From what I understand is your body is releasing insulin to help give u more energy for the workout or to repair your body. Hope that helps. ;)
