[QUOTE="KK123, post: 2358157, member: 451727"] Hi Briony, how long after your exercise did it start to come down and what were your levels like in the following 24 hours or so? I think that everybody's glucose spikes when they do hard exercise (along with the release of other hormones such as cortisol, adrenaline etc) but the difference is that a 'normal' person's body will release the exact amount of insulin to bring it down (or to stop it going too high). I exercise a lot, nothing extreme, mainly running and if I run hard (for any amount of time) OR I run gently but for over 40 minutes, up it goes. Not by a lot but when I am circuit training (not often, mainly for work) I can guarantee it is going to shoot high. For me, it comes down again within an hour and is on the lower side for the whole of the day. I am prepared to put up with that because after months of eating carbs before exercise, eating carbs after, or taking insulin before or after, etc, I realised that all of those methods had a price to pay, ie I'd hypo every other hour following exercise. Now I know how my body is going to react so personally, I test before exercise and if its not too low to begin with, I just get on with it. I test after (thankfully the libre is great for this) and it shows the spike followed quickly by the drop and then quickly again by levelling out to what it started off as! It's definitely a personal thing to try and get right and yes, I wouldn't want it to spike into the 20s so I sympathise, hence me asking how long for. x [/QUOTE]
