What's the lowest reading that's ok before exercising?

What is the lowest reading that is ok before exercise? I try to eat
something before exercise, but since I go low anyways with 20-30 minutes
of walking/stairs, I’m wondering if I should be at a higher starting point.
Right now I want to walk, my reading is 4.8. I did eat something, so I’m
waiting 30 minutes to see if it’s gone up, then I’ll walk.

Just wondering.

    Depends on how vigorous your excercise is going to be. Personally if I’m
    150 and going to cycle for 3+ hours at 15 mph I find starting out at 150
    mgdcl plus eating one banana keeps me within the 120 range.
    Results may vary depending on individual. Don’t try this at home.

    I think this number would vary from person to person.  For me, the lowest
    number before exercising is about 100.  The reason for this is that I can at
    times have a severe drop not only in BG,  but to me on the floor due to
    fainting.  Stairs are particularly problematic for me.  I used to live in an
    apartment with three flights of stairs.  I learned that I could go up and
    down only twice between meals.  If I had to make any more trips than that, I
    had to have a carby snack.

    Now my brother (also type 2) spends most of his time with numbers hovering
    around 80.  Doesn’t seem to matter how much or how little exercise he gets.
    He has never fainted nor had a hypo.

    I’ve noticed the same thing, only with numbers that occasionally go too
    high: no matter how carefully I eat, nor the exercise or lack thereof I
    get, the numbers remain stubbornly high.

    Go figure.

    I try to get mine a bit below 70 mg/dL before doing anything short and
    high intensity, because such activity, and the associated adrenaline
    spike, will drive it up.  If it is long, low-intensity exercise,
    anything in the 90 – 120 range is OK for starting out.

    I once ran a 5k race with a whole blood reading of 90 before the race
    (had not injected or eaten that yet), checked it immediately after and
    it had spiked to 250! Needless to say, I have not let that happen ever
    again.  Letting it get to 250 is most certainly dangerous, both in the
    long term and short term.

     As I said before, it depends upon the individual and what you’re
    getting ready to do.  If you’re getting ready to walk or rake leaves,
    neither of which would likely cause an adrenaline spike, then 120 is
    probably fine for a starting value.  When competition is involved,
    that is not always the case.

    Depends upon the individual and whether you’re speaking in terms of
    plasma or whole blood.  Whole blood readings generally convert to
    plasma readings about 10% higher, meaning that a whole blood reading
    of 60 roughly equals a plasma reading of 66.  I’ve seen lab reports
    say that anything under 65 for plasma is considered low.

    250 is not dangerous short term for a type 1.  let it stay their long
    term and it will cause damage.

    I was at 160 before walking three miles briskly…..afterwards I was 130….so
    maybe it depends on what you plan on doing for excercising…..running a
    marathon? I wouldn’t shoot up insulin without eating before running a marathon.

    I prefer to bring a snack with me to the gym in case I go low – not shoot up –
    and test afterwards.

    I’d never excercise at 70. Id get a little carb in me to get it near 110 or 120
    first. but that is just me

    That’s what both my trainer and my diabetic educator recommend – I
    always take a bit of carbs (up to 10 grams) with me for longer
    work-outs, and eat it part-way through. The trainer said it would
    help to keep me from (in his words) "bonking"; the d.e. said it was
    to keep me from going too high (from a liver dump) or too low (if
    the medication was working too well).

    . . . besides, a bit of chocolate tastes good. <grin>
