Blood sugar INCREASING with workout

The other thread on hypoglycemia is a very good, informative thread that people should be aware of. I'm starting this new thread to see if anyone out there has experienced a related situation. I was diagnosed with type 2 diabetes a few years ago. Right around that time (and before I went on glucophage for the diabetes), I came home from practice one night feeling lousy. I checked my glucose level and found it to be 279, which is very high. I continued to test every 15 minutes to half hour to see where it was going and it gradually came down to a normal level. This happened even though I ate a meal after seeing that it was going down (and I felt like I needed food). I never eat for a few hours before a workout, and my glucose levels had been at or near normal for days before this happened. After this incident, I started testing immediately before and after a workout and found that my glucose level ALWAYS goes up after a workout, with nothing but water taken in during the workout. I had several times back then where it went over 200. Nowadays it doesn't go that high, but I am taking glucophage now. My doctor just shakes her head and says "that's not right, it should go down with a workout". Tell me something I don't know! I saw an endocrinologist that thought that this could be consistent with a delayed insulin response that diabetics have, hence the start of my medication. Has anyone else out there seen such a response with their glucose levels?

    Hmmm. BG raising with exercise. Well better to be a bit high then too low when exercising. The real question is how is your long term control? High 200's are one thing if you are down under 140-150 most of the day or at least under 200 as opposed to being up over 200 all the time. High BG can hurt you over time but so can low/ high HDL-LDL ratios in some people. Exercise should raise your HDL-C which with type II can be depressed as you may know and may contribute to heart trouble so you do need exercise. Have you tried Avandia ? Its not for people with serious liver trouble but does a good job with lots of people with type II DM. It is good in a sense as it keeps BG from going too low . Well your Dr. knows your situation best. Now if you are doing a BG check right after exercise it may not go down especially after you have eaten if you did. Also with some meds BG may not come down that much with exercise alone if you are eating enough.
