If Your Blood Sugar Is Borderline — I Look at the Swing First

"Not diabetes, they said, borderline. Manage it — but manage what, how?"

I hear this after health checks. Not a place they give you medicine, and not a place anyone calls fine.

I look at this place a little differently.

The body adapts to high, to a degree

This is what I say in the consulting room all the time.

The body adapts, to a degree and over time, to high or to low. Blood sugar a little high, and the body resets its baseline to that height. Which is why some people carry a fairly high number and feel nothing at all.

That doesn't mean high is fine. Left high for long, vessels are damaged. That has to be watched in its own right — it is why we do the checks.

But high isn't much felt at the time. Vessels are damaged quietly, over years.

What is hard for you right now — that is usually the swing. When the range it moves through widens, that is felt the same day.

Same average, and a body that flows smoothly and a body that lurches are not alike. On the average they look identical; the person living in them feels nothing of the sort.

Why a swing is felt straight away

Because nerves are sensitive to change. In a quiet room you can hear the fridge; in a noisy one you can't. What nerves measure includes not only size but how much it changed.

Blood sugar too. In the moment it drops away, the body reads it as danger. Then whatever pulls it back up works in a hurry. Hands shaking, cold sweat, a sudden craving for something sweet — that is that moment.

And when it swings suddenly toward less function, the body worries about it and reacts strongly. Falling is the more urgent thing, as far as the body is concerned.

So the high runs quietly and the swing makes a noise.

Sleepy after eating, hunger arriving a few hours later, eating in a hurry then too — that is how the day gets built. (Post-meal sleepiness and chronic fatigue — what your metabolism is signalling)

So metabolic syndrome starts before the numbers

Here is the part that matters.

For the swing to widen, something has to be true first. The vessel that receives has to have shrunk.

Eat, and sugar comes in. If muscle takes it, it passes smoothly. But if muscle has dwindled there is nowhere for it to go, and it spikes. If digestion is patchy and it goes through unevenly, the speed coming in isn't even to begin with.

So I take metabolic syndrome to begin, in many cases, well before the numbers rise — where function starts to drop.

Getting older, muscle weakening, digestion not what it was — around then. The numbers show up much later. If a check called you borderline, in the body it started long ago.

So in the consulting room

Borderline isn't yet a place to press down with medicine. So what do we do — I look first at reducing the swing. Which means growing the vessel that receives.

Muscle first. Not serious exercise — walking, to start. Of the vessels that take in the sugar you eat, muscle is the biggest.

Digestion second. Even the speed coming in, and the curve going out is gentler.

Sleep third. Short sleep and the whole of the next day's curve is rough.

I watch the numbers too. It's just that rather than wrestling with the number alone, it works better to mend the conditions that swing it.

If they called it borderline, that isn't only bad news.

It means there is still swing and nothing has set yet — and this is the easiest place there is to work on.
