Delivery after reconnecting post a swim

[claire mccann]

Hi this is a bit random. I disconnect pump to swim and sometimes find when I reconnect if there is no bolus (only standard basal rate) blood sugar shots up very quickly as though the standard basal isn’t getting in.

Does anyone else experience this?

Thanks

Hi @claire mccann

If you remove your pump then your not getting your basal during the time you are disconnected so this will mean your levels will rise, I disconnect sometimes when I run but will always do a bolus top up at the end otherwise I will go high.

I get that but usually when I get out it’s a bit low (like between 3 & 4) but then rises really quickly? Moreso than usual

Hi @claire mccann

Swimming can send me hypo too, but also remember if your going hypo the your liver will also dump some glucose into your system too causing a rise. If i’m below 7 before hitting the pool then i’ll have a 10g carb snack so biscuit beforehand to keep me safe, I only swim for 40 mins so that works for me.

If you keep a diary of your swims then you can see what works and what doesn’t - it’s never an exact science though as your exercising, the pool temperature is another consideration, insulin on board, other hormones at play etc, but at least it will help you build a picture and identify a plan to manage it.

Hi Claire, I've just swum 84 lengths today and the way I work it is, I suspend the dosage and turn my sensor connection off. I try to get my sugars at around 9 and normally find they come down to around 6ish after the swim. All of us will differ and it all depends how hard you work on your swim as that can alter your levels quite a bit. My sugar level was 11 today but because I worked pretty hard in my swim they dropped to 6.7 which was fab. After my swim I turn my pump back on and reconnect my sensor as well as taking a blood sugar reading to help my sensor adjust if required. I'm using the Medtronic 670g pump by the way.
