What It Measures in Kaizora
Interstitial Fluid Glucose, the glucose in the fluid under your skin, every few minutes. Kaizora keeps it apart from Capillary Blood Glucose from a fingerstick meter, since the two are different quantities.
- Glucose
How It Gets to Kaizora
Through Apple Health: turn on sharing with Apple Health in the Stelo app, then export all your health data from the Health app and import the file. Kaizora recognizes Stelo’s readings as a CGM’s.
Strengths
- Sold without a prescription.
- Readings every few minutes, day and night, show what a fingerstick can’t: how your glucose moves between meals and overnight.
Limits
- Not for people who take insulin or have problematic low blood sugar.
- Stelo shares readings with Apple Health about three hours late.
- Sensors are used up every 15 days, so it’s an ongoing cost.
- Sold in the United States.
About What It Measures
What Are Normal Glucose Levels After a Meal?
What a CGM shows in people without diabetes, the diagnostic thresholds for fasting and two hours after glucose, why a spike after a meal isn't a diagnosis, and how to read your own curves.
Why Your CGM and Your Glucose Meter Disagree
A continuous glucose monitor measures the fluid under your skin, a meter measures blood. Why the two differ, especially when glucose is changing, how accurate each is allowed to be, and when to trust which.
