Hi LindyK. You’ve got yourself a right active one there. Fear not, though, it is manageable.
One of the issues you have is the different types of activity, which will affect BGs is different ways. Swimming (if it’s similar to how my daughter trains) will be done at a steady rate, while football will be in bursts. Are they immediately after each other or is there a gap? Either way, it might be worth having different strategies for each and dealing with them separately. Don’t do anything about football until after swimming. It will very much be trial and error, but here are some suggestions for swimming.
- Less insulin with the meal before and an insulin treated snack before swimming.
- As above, but no insulin with the snack.
- Usual insulin with the meal before and a non-insulin treated snack before swimming.
Option 2 worked for my daughter, but your son may be different.
Another factor is the delayed reaction your son’s body has to the swimming, which will be a factor in what happens during football. Because football is steady activity with intermittent bursts (unless he’s a goalkeeper), what works for swimming may well work for football, with a top-up of carbs needed at half time if he’s playing a match. Cross-country is a similar type of activity to swimming, so you may find that a similar strategy works there, too.
Ultimately, it will be a matter of experimenting to find what works.
I hope I haven’t confused you and let me know if you want anymore info.
