Swimming: A New Challenge
Over the past 1,700 miles, I’ve gotten pretty good at controlling my BG while running. Well, at least running first thing in the morning. Running in the afternoon after lunch is still a bit of an adventure. But, now I need to get a handle on my plan for swimming.
I have been following the same plan for swimming in the morning as I do for running. 2 hours before my swim, I will knock down my basal around 50% and and hour before, I’ll knock it down another notch. I will also eat 20-30 carbs about 10 minutes before starting. This works very well for preventing lows during 30-40 minute swims. I usually come out of the water just a tad higher than I started, but for the most part, perfect. The issue I’m having is dealing with a HUGE spike about 2 hours later. We’re talking HUGE. Jumping up 200+ from where I was right after getting out of the water. This is even with giving myself a fairly large bolus to cover my after swim snack and to try and make up for the lowered basal. I have to watch post-run highs, but they are nothing compared to what is going on after swimming.
One big difference to note is that I am not wearing my pump in the pool, so I’m getting no insulin for 30-40 minutes (oh, don’t forget shower time too). This is much different from running where I’m wearing my pump and I try to let my basal rate go back to normal levels about 30 minutes before I’m done. As I’m writing this and thinking about it, this is probably my problem. Writing this blog is good for something…
So, the first thing I will try is reducing my basal only 1 hour prior to my start, but still plan to eat 20-30 carbs. I’ll try this approach for my shorter 30-40 minute swims and see how it goes. Once I get into the 1 hour plus range it’ll be a whole new ballgame. I may even try to give myself a small bolus right before starting in effort to cover the time I won’t be wearing the pump.
I look forward to future lows in the water. It’ll be fun.
