Monitoring blood glucose during exercise in type 1 diabetes

It is important that if you are using injected insulin for your type 1 diabetes that you test your blood glucose levels regularly to avoid blood glucose highs (hyperglycaemia) and lows (also known as ‘hypos’ or hypoglycaemia).

You may need to check your blood glucose levels before and after exercise, and eat extra glucose-containing food (carbohydrates) before or during exercise, and/or reduce your medicine dose. A health professional can provide advice.
