Sports And Exercise: The Ultimate Challenge In Blood Sugar Control

by gary scheiner, MS, CDE Sometimes, it amazes me how smart the pancreas really is. It always seems to know what to do to keep blood sugars in range, even under the most challenging circumstances. Having an argument with your partner? It churns out some extra insulin to offset the “fight or flight” response (make that flight only, if you’re smart). Upset stomach keeping you from eating the way you normally eat? Insulin secretion drops off a bit. Can’t resist the aroma of a fresh bagel (something that, in my opinion, was forged by the Diabetes Devil himself)? Pancreas cranks out just enough to cover it. Participation in sports and exercise presents a special challenge. That’s because physical activity can affect blood sugar in multiple ways. With increased activity, muscle cells become much more sensitive to insulin.

    My son is 8yrs old. His pump site is on his bottom. (he's thin and can't handle using his stomach)
    We're taking a 2 week vacation soon that will include swimming every day. We hit the parks at RD and then return to our condo for a midday swim. The second half of our vacation will be on the cruise so we'll be at the pools every day and at Castaway Cay. We have a very hard time keeping his site when it gets wet. Showers and baths make his site come off! So frustrating. How do we handle swimming every day?
    We've tried IV "skin" over top of his site (we cut a hole large enough to go around the connecter piece and we've tried the sticky wipes that make his skin stickier....neither have worked very well. We only had samples of the sticky wipes, so maybe we didn't use enough?
    How do you keep a site on through daily swim sessions?
