[QUOTE="Brunneria, post: 959474, member: 41816"] Thanks for answering the questions. :) I would say that 2 mmol/l is nothing to worry about. If you are sedentary (ish) then your body is probably thinking (what the heck! This is unusual! Maybe i should prepare a bit of extra energy to be available in case this weird activity continues!') ;) It will be taking a bit of your glycogen store from the liver, breaking it down into glucose and letting it float around in the bloodstream just in case you decide to do something really freaky, like run up a flight of stairs and punch the air (Like Rocky at the end of his training runs) The increased movement and activity will increase the blood supply to your muscles, and they will use up 2 points worth of glucose in the next few mins or hours. As a very general rule, gentle exercise tends to lower bg a bit. While intense exercise raises bg a bit. That is in the short term. However, over the longer term (several hours, sometimes even the rest of the day) bg tends to drift a bit lower. The fitter you are, the harder you have to exercise to see these effects. So a sedentary person may see the up-then-down effect with a trundle round the block or a single flight of stairs. An athlete may have to run a significant distance to get the effect. In your situation, i would conduct a wee experiment (i love these little adventures). Check your bg before you start. Do a brisk walk round the block. Test your bg at the end, then once an hour for a few hours. You should see a short term rise followed by a drift down, possibly to a lower level than your starting point Result: an overall benefit Repeat this for several days. As your body adjusts, you will probably see a smaller rise, and more sustained benefit. Once you have got used to that level of activity, if you want greater benefits, then you can increase the intensity, or increase the duration of the exercise. Oh, and to give you a sense of the impact of different bg rises, type 1 diabetics are advised not to exercise at over 13mmol/l, most doctors say don't be over 7.8 mmol/l at 2 hours after food (but accept that you may be much higher than that at 1 hour after food), and any form of stress/excitement/shock (from a job interview to running for the bus, to an argument, to going on a blind date) will raise your bg. There is nothing inherently wrong with temporarily somewhat raised bg. The problems come when that rise is extreme, sustained and uncontrolled. Hope that helps. Oh, and one more thing. Several of us use these trackable benefits to help control our bg. Let's say i am in a situation where a few extra carbs sneak into my evening meal. My bg is likely to rise higher than normal, isnt it? Since i don't want that, i can use exercise to drive the bg down again. A brisk walk, a quick blast up and down a few flights of stairs, a bout on the exercise bike, and my muscles burn up that extra glucose as it arrives in the bloodstream after food. This is not a cure-all, because if the meal is large and slow to digest, the bg rise may be longer, bigger and lingering, but it is a good thing to keep in your toolbox, if you need. :) [/QUOTE]
