What causes hyperglycemia?
A number of things can cause hyperglycemia: • If you have type 1, you may not have given yourself enough insulin. • If you have type 2, your body may have enough insulin, but it is not as effective as it should be. • You ate more than planned or exercised less than planned. • You have stress from an illness, such as a cold or flu. • You have other stress, such as family conflicts or school or dating problems.
