The episode, word for word
Your kidneys are trying to save your life.
And in the process, they're making your blood sugar impossible to manage.
Here's what I mean: when your blood sugar goes high, your kidneys don't just sit there. They dump glucose into your urine to protect you. But glucose doesn't leave alone, it drags water with it. So you pee out the glucose and the hydration. Your blood volume drops. And now the glucose that's still floating around? It's in less liquid. So your CGM reads even higher.
You didn't eat more carbs. You just lost water. And your kidneys are still flushing. And the cycle keeps going.
It's called osmotic diuresis, and it's the reason you can bolus twice and still be stuck at 180 for two hours.
Today we're breaking down the loop. And more importantly, how to stop it.
My name is Neil Greathouse, and this is Your Best T1D Year.
Alright, let's walk through this step by step.
Step one: Your blood sugar goes high. Maybe you had pizza. Maybe you miscounted carbs. Maybe stress cortisol decided to crash the party. Doesn't matter. High blood sugar happens.
Step two: Your kidneys notice. And they do their job, they try to flush out the extra glucose through your urine. That process is called osmotic diuresis. It's your body trying to protect you from syrup blood.
Step three: But glucose doesn't leave alone. It drags water with it. Every time you pee, you're losing water and glucose. Your blood volume drops.
Step four: Now here's where it gets tricky. When there's less water in your bloodstream, the glucose that's still there becomes more concentrated. Same amount of glucose. Less liquid. Your CGM reads higher, not because you ate more, but because the ratio changed.
Think of it like orange juice. You've got a cup of OJ. If you add water, it gets lighter. If you let the water evaporate, it gets thicker, more concentrated. Same juice. Different amount of liquid. That's your blood when you're dehydrated.
Step five: And because your CGM now reads higher, your kidneys keep flushing. Which makes you pee more. Which dehydrates you more. Which concentrates your blood more. And the loop keeps going.
Non-diabetics don't deal with this. Their bodies regulate glucose without dumping it into their urine. But we don't have that option. High blood sugar equals osmotic diuresis. Osmotic diuresis equals dehydration. Dehydration equals higher-looking blood sugar.
It's a feedback loop. And it's exhausting.
Even when you correct the high, your body's still playing catch-up. You've lost water. Your blood volume is lower. Your insulin has to work harder to push through tissue that's less hydrated. Everything slows down.
So what's the fix? You refill what T1D drains. You drink more water. Not because it's magic. But because it breaks the cycle.
More water equals better blood volume. Better blood volume equals less concentration. Less concentration equals more accurate CGM readings. More accurate readings equal faster insulin action.
You don't need a home run here. You just need to get on base. Add one more cup of water today than you drank yesterday. That's it.
James Clear calls it the 1% rule in Atomic Habits. You don't need to overhaul your life. You just need to be 1% better than yesterday. One more cup. One refill. One Owala top-off between meetings.
Small habits compound. That's how you win with T1D.
And real quick, no, that iced coffee from Starbucks doesn't count as your morning water.
Coffee's great. I love coffee. But caffeine is a diuretic. It makes you pee more, which is the opposite of what we're trying to do here. We'll talk more about what counts and what doesn't next Monday. But for now: water first, coffee second.
If you're tired of fighting the healthcare system just to get basic care, I want you to check out Blue Circle Health.
They've created a free, virtual care program with real endocrinologists, diabetes educators, and social workers who actually get it. They're helping people who've been told "no" for years finally get CGMs, insulin, support, and actual progress.
This isn't charity. This is leadership.

Alright, here's your move for today: drink one more cup of water than you did yesterday.
If you drank two cups yesterday, go for three today. If you drank four, go for five. You're not chasing perfection. You're chasing progress.
Track it. Snap a photo of your water bottle. Post it to your Story and tag @thebetes. Let's do this together.
Here's the thing: T1D is relentless. You can do everything right and still have a bad day. But hydration is one of the few things you actually control.
You can't fix your beta cells. You can't reverse your autoimmune system. But you can fill your water bottle. And when you do, everything gets a little easier.
You don't need a home run. You just need to get on base. One cup at a time.
I'll see you Friday.
Type 1 diabetes is relentless, but managing it doesn't have to be. New episodes drop every Monday, Wednesday, and Friday.
You're not doing a bad job, you're doing a difficult job. Nobody remembers easy.
