Glucose and ketone levels don’t always trend in the same direction3.
Ketones can be high even when your glucose looks normal.
Introducing Libre DUO 10 Day system.
The world’s first dual glucose ketone sensor‖ is coming soon.
The U.S. Food and Drug Administration (FDA) has authorized the Libre DUO 10 Day system. Soon, you’ll be able to see your glucose and ketone readings from one sensor.
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.
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.
