A lack of insulin, due possibly to poor absorption, illness or missed doses—can cause ketone production. This can lead to ketoacidosis, dangerously high levels of ketones and blood sugar.
Some ways to prevent ketoacidosis:
- check for ketones prior to exercise when blood-glucose levels are high for no apparent reason
- do not exercise when ketones are positive
- if you have missed a dose of insulin, put off exercising until you have adjusted for it
- do not disconnect pump for more than 90 minutes without replacing insulin
Athletes with T1D should plan ahead and take precautions to keep exercise and blood sugar in balance.
People with T1D must consider many factors that affect blood glucose during exercise: active insulin, infusion site (remove pump or not), food consumed, time of day, weather, emotional state, duration and intensity of the activity… and yet physical activity is so important. Exercise is for everyone. People with T1D plan for everything they do—the same patience, flexibility, cautions and spirit should be applied to exercise. Have fun and get out there.
