High blood sugar level after football

[niyathireme]

I am skipping my daily badminton and going for 1.5 HR football match on Saturday and Sunday. When I check my glucose level it's showing 300mg/dl . It gets normal in the morning thou. I am so confused by this. I thought football was an ideal exercise for T1D .

Is it a proper football match? It could be because you're feeling quite competitive it's setting off adrenaline, which can cause you to go up a bit because while you've got adrenaline floating round you're system you will be less insulin sensitive. Also is playing football a bit HIIT? Are you a bit stop & start (I've never even tried to play football, can you tell)? I find intervals do send me up a bit.

But just because it sends you higher doesn't mean it's bad for diabetics, you just need to figure out a way to deal with it. A lot of people bolus for exercise, but obviously you should be careful and cautious if you chose to do this because as soon as the stress stops (the match is over) you could drop like a stone. I find exercise better for my blood sugar if I do a gentle steady aerobic exercise as a cool down - so is it an option for you to play your match & then walk home at a gentle stroll?

When I play badminton, my BG goes up. I eat low carb 2 hours before the game and bolus for it, so that some NovoRapid is still present in my body into the game. This helps me not going too high. Needless to say, you need to be very careful and test often before you figure out the right bolus and timing.

Hi @niyathireme
Are you checking your blood glucose just before the match? If your blood glucose is raised before a match and you have keytones the exercise will just increase the toxicity therefore significantly raising your blood glucose levels.
The other option is that it's the effect of adrenaline as suggested by @catapillar .

If you are testing before your match and all is normal, you should be looking to take on some carbs before exercise otherwise if you run low during exercise your liver may be 'sugar-dumping' glucose into the blood, which later on when the body is calmer it will take the sugar back and may cause you to hypo. It's important to test after strenuous exercise, and advisable to check again an hour later. If you keep a diary it will help you establish a pattern and give you references for the future.

Also make sure you are drinking plenty of water, as this can help keep the bs in check.

I used to eat carbs before playing badminton and it would make me go unnecessarily high during the game (lots of adrenalin involved) which would affect my performance. I usually play for 60 to 90 minutes of what is a very intense game. My BS would decrease by about 1 mmol in the first 20 minutes and then would increase by about 3 mmol. For the next three days I experience higher insulin sensitivity and generally lower BG levels.
