When using an insulin pump, it is important to understand that when insulin flow stops, the blood glucose (sugar) will rise quickly. A sudden high blood glucose could be related to an insulin pump problem.
When the body does not have enough insulin, blood glucose rises quickly. This can lead to diabetic ketoacidosis (DKA). Fat is burned for energy. The breakdown of fat produces ketones which are an acid. When ketones build up in the blood, this is called DKA.
DKA can occur quickly and can be life threatening. For this reason, an unexpected blood glucose over 250 should never be ignored.
