Sometimes your Dexcom and finger stick show completely different numbers.

A lot of people think Dexcom works on a 20 point rule, but that’s not actually how CGM accuracy works.

Dexcom uses a 20 percent rule, which means readings can vary depending on the glucose level.

Understanding this can make diabetes technology a lot less confusing.

🩸 Dexcom says one number… finger stick says another.

If you live with diabetes, you’ve probably asked:

Which one is right?

In this episode of Glucose Guy, we break down the Dexcom 20% Rule and explain why CGM readings and finger sticks don’t always match.

Understanding this can make diabetes technology a lot less confusing.

4 AM.

Dexcom alarms.
Finger sticks.
Numbers that don’t make sense.

One night last week was one of those nights where diabetes just kept throwing curveballs.

By the time things finally settled down it was after 4 AM.

If you care for a child with Type 1 Diabetes, you probably know exactly what nights like this feel like.

Tomorrow I’m releasing a video explaining why Dexcom readings and finger sticks don’t always match, and why nights like this can happen.

But this video is just the reality of what it feels like in the moment.

Insulin pumps use two main types of insulin delivery: basal insulin for background needs and bolus insulin for meals and corrections. This quick breakdown explains how insulin pumps work in real life and why they can offer more flexibility than injections for many families living with Type 1 diabetes.

Ever wonder how an insulin pump actually delivers insulin into the body? From pump hardware and tubing to patch pumps and cannulas, this quick breakdown explains how insulin pumps work and how closed loop systems adjust insulin using CGM data. Simple diabetes tech explained for parents and families living with Type 1 diabetes.

INSULIN PUMPS — How They Work (Basal, Bolus & Closed Loop Explained)

Ever wonder how insulin pumps actually work? Basal vs bolus. Tubing vs patch pumps. How pumps talk to CGMs.

In this episode of Glucose Guy, I break insulin pumps down in plain English for parents, caregivers, and anyone living with Type 1 diabetes. No jargon. No overwhelm. Just real-world explanation.

Continuous glucose monitors are incredible tools, but they don’t show real-time blood sugar. CGM readings come from interstitial fluid, which naturally lags behind what’s happening in your bloodstream. Knowing this can help people avoid overcorrecting highs and lows and better trust their diabetes technology.

How does a CGM actually know your blood sugar — and why does it sometimes feel “behind”? In today’s Glucose Guy episode, I break down how continuous glucose monitors work, what they’re really measuring, and how to use trend arrows to make smarter day-to-day decisions with diabetes tech.

Most people think a CGM just gives you a blood sugar number — but what’s really powerful is how the sensor works and what those trend arrows mean. Understanding how continuous glucose monitors track changes in glucose levels can help people with diabetes avoid sudden highs and lows and make safer daily decisions.
