Why wear your insulin pump during sport?

If an individual removes their insulin pump during sports activities, insulin delivery stops, and blood glucose levels can rise rapidly. This is because the body is no longer receiving the steady flow of insulin from the pump, and there is no mechanism to replace the lost basal insulin. As a result, blood glucose levels can rise above the target range, leading to hyperglycemia and potential health risks.

As adrenaline is released during intense exercise, it can cause the liver to release stored glucose into the bloodstream, resulting in a spike in blood sugar levels. For someone with type 1 diabetes, this can be particularly problematic, as their body does not produce insulin, which is needed to transport glucose into cells for energy. As blood sugar levels rise, performance levels drop.  Athletes can suffer from dehydration, cramps, blurry vision, headaches, fatigue and weakness.

Removing an insulin pump for an extended period of time can also increase your risk of DKA (Diabetic Ketoacidosis), a serious condition that occurs when the body produces high levels of ketones in response to a lack of insulin.

On the other hand...

If an individual engages in sports activities with their insulin pump on, they can adjust their insulin dosages to match their activity level and food intake. This can help them maintain optimal blood glucose levels during sports activities, enhancing their sports performance and reducing the risk of health complications.

It is important to have regular
communication with a health care provider to ensure that the individual's diabetes management plan is appropriate for their level of physical activity.
