People with diabetes should learn to recognize the early warning signs and symptoms of ketoacidosis. In people with infections or who are on insulin pump therapy, measuring urine ketones can give more information than glucose measurements alone.
Insulin pump users need to check often to see that insulin is still flowing through the tubing, and that there are no blockages, kinks, or disconnections.
