High Blood Pressure and Kidney Health
The two-way link between high blood pressure and kidney damage, and how controlling BP protects your kidneys.
High blood pressure is both a cause and a result of kidney disease. Uncontrolled BP damages kidney vessels, while failing kidneys make BP harder to control.
How BP harms the kidneys
Sustained pressure strains the small vessels in the kidney filters, causing them to thicken and scar. Over years, filtering capacity falls.
The target to aim for
For most people with kidney disease, the aim is usually below 130/80 mmHg. Your doctor sets a personal target.
What helps
- ✓Take BP medicines (often ACE inhibitors or ARBs) as prescribed
- ✓Cut salt
- ✓Stay active and keep a healthy weight
- ✓Avoid smoking and limit alcohol
Frequently Asked Questions
Which medicine protects the kidneys?
ACE inhibitors and ARBs reduce pressure inside the kidney filters and slow protein leak. Your doctor decides.
Can lowering BP improve kidney function?
It can slow the loss of function and reduce protein in urine, though it cannot repair already-scarred kidneys.
