Is exercise pushing my blood sugar up?

Hello, I am newly diagnosed (6 weeks ago), after a random blood test gave a reading of 18 followed by an HbA1C of 97. GP suggested I try to lose some weight (BMI of 27) and retest the HbA1C in 3 months before considering meds.

Since then I have researched on here, and stuck to a LCHF diet. I have also increased my exercise levels. I used to do 3 or 4 hours of classes at my gym per week, but now am trying to do 7 or 8. I eat as soon as i come home from work and then go to the gym.

After advice on here, I bought a meter which arrived a week ago, and have been testing to try to identify which foods are pushing my bs levels up. On Monday I was horrified to find that my reading jumped from 5.3 before dinner to 8.7 2 hours after, I then tested again after 3 hours and the reading was 10. A similar thing happened throughout the week, although the spikes weren't as high - 8s and 9s though. However, these readings were all taken after exercise. So on Monday, the 2 hour reading was after I had done an hour's HIIT class, and I followed that by an hours kettlebell class, which is when I got the reading of 10.

Fridays are a bit different as I do a class on the way home from work and then eat later. So yesterday, my post lunch readings were 6.8 (1 hour) and 6.1 (2 hours). I then tested immediately before going to the gym, which was 4 hours after lunch, and my reading was 5.6. I did an hour of circuit training, tested straight afterwards and my reading was 7.1. After another hour it had risen to 8.7 despite me not eating. I then ate dinner (which by chance was the same dinner as on Monday). 1 hour after dinner my reading was 8.6 and after 2 hours it was 6.7. So my readings were lower after eating than they were after exercising and not eating.....

So it looks as though the high readings I had earlier in the week were possibly affected by the exercise. I'm now concerned that, despite my hard work with the diet, my readings will be high because of the exercise. And i won't be able to work out how the food itself is really affecting me.

Has anyone had a similar experience? I'm reluctant to stop exercising. I could change the intensity and see if that made a difference? If anyone has some useful advice, I'd love to hear it. Everything I've read so far stresses that diet and exercise together are the way forward.

Your rise in levels may be caused by not eating before you exercise. I do a lot of cycling (60kms a day) and I discovered that if I didn't eat before I rode my levels rose. Seems that if you don't have food to be turned into enegy your body generates its own by secreting stored up glucose. At least that is my finding.
