Kidney Health Blind Spots: The One Test Your Doctor Isn't Running (Ep. 305)

In Episode 305 of the Fit Father Project Podcast, I continue our Blind Spots series — episode five of six — by uncovering one of the biggest kidney health blind spots in modern medicine:

...Almost nobody gets tested for urine albumin, the earliest warning sign of kidney damage.

More than 1 in 7 American adults have chronic kidney disease. Nine out of ten don't know it.

This organ runs your blood pressure, your red blood cell production, your active vitamin D, and your electrolyte balance — and it fails silently, with no pain, until something breaks.

I walk through the seven real jobs your kidneys do, bust the myth that high protein and creatine damage healthy kidneys, explain why your EGFR can lie to you if you lift weights, and give you the exact labs to ask your doctor for at your next physical.

If you've been treating your kidneys as an afterthought, this episode closes that kidney health blind spot for good.
