Hi
I've been type 1 for just over a year now. I've got my bg levels to between 5-6 before meals and always under 8 two hours after meals. I low carb as my body just can't take them and it's working for me. I'm trying to keep fit and loose weight but every time I exercise my bg gets higher!! Does anyone know why this happens? I always check my bg before and it's normally under 6
Any one have the same reaction ? Please help xxx
 
I'm type 2 without a meter so can't help but someone will I vaguely remember reading something about this somewhere before on here so the knowledge is with someone on the board
 
In a normal person when you begin exercise the body does two things:

1. It stops / slows the release of insulin.
2. It dumps glucose from the liver to power muscles.

Now in us type I's clearly the first step doesn't happen (or it does but we control that manually!) but our bodies still release glucose this can cause blood glucose to rise. What you will probably find that in the first 10 minutes of exercise your blood glucose will drop.. at this point the liver starts its glucose dump.. now depending on the intensity of the exercise one of three things will happen... either your blood glucose will rise, stay stable or drop... what's important to remember is that even if it has risen at the end of the exercise your muscles are going to be busy replenishing glucose for a number of hours after exercise and this can lower blood glucose unexpectedly.. so make sure you keep an eye on those blood glucose.
 
yep, everything that Pneu just said.
Exercise is annoyingly hard to manage in T1 diabetes.
Shortly after I was diagnosed I went on a hiking holiday where I was covering 20 miles or more each day. Struggled with hypos all through the walk, then each evening my bg would go through the roof, as if my not-terribly-efficient liver was saying, "oh, did you want some extra sugar? sorry about that, better late than never."
It might be worth experimenting with even lower-impact forms of exercise, or maybe see what happens if you warm up more slowly rather than starting off suddenly? Alternatively, you may just find that putting up with a slightly higher bg for a short while isn't the end of the world. It depends how high it is going and for how long.
Be careful about correcting the high dose though, because of what Pneu said about the liver needing to replenish its stocks.
 
Exercise is most important for human life but Diabetes people must have do walk or exercise minimum 45 minute , for controlling sugar level.
 
High intensity Anaerobic exercise can cause hyperglycemia and aerobic exercise can cause hypoglycemia. Exercise is great for lowering BG levels!
