Signs your kidneys aren't working well and how to improve them

Kidneys don't give warnings. They don't hurt, they don't complain, and they can lose a significant part of their capacity without you noticing anything.

That is why it is worth looking at the small signs: urine that is foamy and takes time to flush, ankles that show sock marks, blood pressure that rises for no clear reason, and fatigue that sleep does not explain.

None of these signs confirm anything. All of them deserve a blood test.

And that is the problem. Almost all of us look at creatinine and glomerular filtration rate, but very few people request the other data point: urinary albumin.

A joint analysis of general population cohorts gathered more than a million people, about one hundred thousand with albumin measured precisely in urine, and followed their mortality for years.

Result: low filtration and albumin in the urine were associated with higher mortality, each one independently. And the risk from albumin rose even at levels that many reports mark as normal.

In other words, two people with the same filtration rate can have very different risks depending on whether or not they are losing protein through their urine.

These are observational data. They show association, not causation. But they point to something practical: with a single marker, you do not see the same thing as you do with two.

This study did not analyze what damages the kidney. What we know from other sources is boring: sustained high blood pressure, sustained high glucose, and anti-inflammatories taken out of habit.

Taking care of your kidneys is not an exotic protocol. It is about controlling your blood pressure and glucose, and stopping the self-medication every time something bothers you.

The organ that does not hurt is the one you need to monitor in writing.

Your 1% improvement for today.

Ask for the albumin/creatinine ratio in your urine during your next blood test. It is cheap, requested in a minute, and gives you information that creatinine alone does not.

This is what I cover in the Longevity Workshop and Private Longevity WhatsApp Group: In the workshop, I teach you what to ask for in your lab work—including urine albumin—and in the group, we resolve your questions when interpreting it.
