The “Gluc-Coaster”: Why Your Blood Sugar Feels So Chaotic

Blood sugar with type 1 diabetes can sometimes feel unpredictable.

You count carbs
You take insulin
You follow the plan

And your numbers still do something completely different.

If that experience feels familiar, you’re not alone in it.

In this episode I break down something that many people with t1d were never fully taught:

Blood sugar often follows patterns. And those patterns can sometimes be understood.

One concept that comes up again and again in diabetes management is this:

Blood sugar has momentum
And insulin has momentum too.

When those two things aren’t aligned, it can create the cycle many people experience:

High → correction → low → treatment → spike again.

What I call the “Gluc-Coaster.”

For many people living with type 1 diabetes, the hardest part isn’t just managing blood sugar. It’s feeling like the numbers don’t make sense.

And when the numbers don’t make sense, it’s easy to start believing that you’re doing something wrong.

But in many cases, blood sugar changes are responding to real physiological factors like:

✨ hormone shifts in the morning
✨ insulin timing relative to meals
✨ digestion patterns from certain foods
✨ stress, sleep, or illness
✨ the natural delay between CGM data and real-time blood sugar

When these factors aren’t explained clearly, diabetes management can start to feel like guesswork.

I walk through several experiences many people with t1d recognize, including:

📌 why blood sugar may spike at breakfast even when you “do everything right”
📌 why correcting highs can sometimes lead to later lows
📌 why overnight spikes often have traceable explanations
📌 why insulin timing can influence blood sugar more than many people realize

Most importantly, this conversation highlights something that can be easy to forget when living with diabetes every day:

Your blood sugar is information.

In many cases, it’s not random, and it’s not a reflection of your effort.

Understanding the patterns behind your numbers can sometimes make diabetes feel a little less overwhelming and a little more manageable over time.
