Exercising whilst wearing
an insulin pump and CGM
with an advanced algorithm
Although exercise is healthy for people with diabetes it can result in unpredictable changes in glucose levels that may challenge an artificial pancreas. Also, different types of exercise have differing effects on glucose levels in people with type 1 diabetes. These contrasting responses to exercise make generalizing recommendations for exercise preparation difficult in people with type 1 diabetes, and currently recommended pre-exercise strategies require the person with diabetes to actively plan in advance the timing of their exercise.
One strategy is to set a ‘temporary glucose target’, which means the artificial pancreas targets a higher glucose level, effectively reducing the insulin delivered. It is currently recommended that this occurs 60-120 min prior to exercise. However, it is important to consider the optimal timing for the implementation of these pre-exercise strategies using an artificial pancreas. If good glucose control can be achieved when a temporary target is initiated close to, or at the beginning of exercise, then this would minimize the burden of exercise and could improve rates of exercise participation.
