[QUOTE="EllieM, post: 2357778, member: 372717"] HI Briony, I get this to a certain extent with high intensity exercise, I assume because I'm quite insulin resistant (thanks T2 dad) and the stress hormones activated by HIT make my liver dump glucose? (I'm sure someone will correct me if I've misunderstood the mechanism). It always seems a bit of a lottery, because moderate intensity exercise (walking the dog etc) improves my insulin resistance and makes me go low... So, some thoughts. I'm assuming you're not wearing a pump because if you were you could just increase your basal for exercise. Consider prebolusing for exercise? I wear a dexcom so I can see pretty fast if my levels are rising or lowering in a gym session. If they are rising unacceptably I'll pop an extra 1 or 2 units. Obviously the quantity depends on your own body, and you'd need to work it out. Predexcom I'd do a blood test before the session and then maybe 1 or 2 during, just to see what's happening. Another thought, I find that my insulin resistance gets worse when my blood sugar starts to go high. Your spike might have been less if you'd started at 6.4..... Also, it may (or may not) make a difference if you exercise just after a meal (bolus from the meal still in your system and maybe the exercise will make you less insulin resistant) compared to before a meal (nothing in there apart from your basal) Really, you'll have to experiment and test test test. And if that 23 was from a sensor not a blood test, consider sensor error.... They are not at all accurate at higher levels. (And honestly, if it was from a glucometer, always wash your hands and try again, as it may have been a glucometer error.) Good luck. I'm sure you'll be able to work it out eventually. Don't let the spike put you off exercise, as in the long run it'll help you. [/QUOTE]
