Introducing the Libre DUO 10 Day system.

What is DKA?
Diabetic ketoacidosis (DKA) is a serious, life-threatening condition2. It can develop when your body doesn’t have enough insulin, causing ketones to build up to dangerous levels2.
Why DKA can be hard to recognize
Glucose and ketone levels don’t always trend in the same direction3.
Ketones can be high even when your glucose looks normal.
Symptoms can look like the flu2.
Early signs of DKA can be easy to mistake for another illness.
DKA can develop quickly4.
Without timely action, rising ketones can quickly progress to DKA.
