15. Proteinuria and Aging: The Time Factor
As we age, our body undergoes a multitude of changes, some more obvious than others. One less-discussed aspect of aging is its impact on kidney function and, consequently, proteinuria. While this may not be the most glamorous topic, it’s a significant part of aging that needs attention.
Firstly, let’s consider glomerular filtration rate (GFR), a crucial kidney function parameter. As we age, GFR naturally decreases. A lower GFR can mean less efficient protein retention, paving the way for an increase in proteinuria, even in otherwise healthy adults.
It’s a biological conundrum: Is it aging itself that leads to proteinuria, or is it the wear and tear on the kidneys over the years? Research is ongoing, but some studies indicate that both factors may contribute. Age-related diseases like diabetes and hypertension can act as catalysts. (15)
