Frequently asked questions
Can high blood pressure damage the kidneys without symptoms?
Yes. Kidney damage from high BP is often silent for years, which is why regular blood pressure and kidney checks matter.
Does controlling blood pressure protect the kidneys?
Yes. Keeping blood pressure in the target range, often with kidney-protective medicines, is one of the best ways to slow kidney damage.
