Physical and leisure activities

The Libre is a fantastic tool for giving you more insight into your blood glucose levels and this is incredibly useful when exercising.

Reviewing your data before, during and after exercising will give you an idea about the impact of a certain type of activity on your blood glucose levels and can help you prepare better in the future, i.e. if you can see that you are having delayed low blood glucose levels after exercising then you could try eating some carbohydrate afterwards to prevent them from getting low.

The trend arrows will indicate whether your blood glucose levels are staying level or going up or down so you can see whether you need to take action or not.

For a more in-depth look at exercising when you have type 1 diabetes, have a look at our ‘Living with Type 1 Diabetes‘ course which covers topics such as insulin & exercise, exercise types and intensity and the impact on blood glucose levels.

Practical issues

If you’re doing exercise then it’s likely that you’ll be sweating, even more so if you are doing some high-intensity activities. This may impact sensor adhesion so if this affects you, then you could think about covering your sensor with patches or a medical dressing.

The other issue that some people experience is accidentally knocking or bumping their sensor when exercising. If this is something that you’ve experienced then there are protective bands that you can buy which are designed to protect the sensor from being knocked.
