Blood Pressure and Kidney Function: How Hypertension and Hypotension Affect GFR
Glomerular filtration rate (GFR) measures kidney filtering capacity. Blood pressure directly influences GFR:
- Hypertension: Chronic high pressure damages renal vessels, causing scarring, nephron loss, decreased GFR, and eventual kidney failure.
- Hypotension: Low pressure reduces renal perfusion, starving nephrons of blood, also decreasing GFR.
Maintaining blood pressure within a healthy range is crucial for preserving kidney function and preventing chronic kidney disease.
