Preventing Kidney Disease
The evidence-based steps that protect the kidneys — controlling diabetes and blood pressure, hydration, and cautious use of medicines.
Last updated: 2026-09-24
Most kidney disease is preventable or can be slowed. Because early disease is asymptomatic, prevention means acting on risk factors before symptoms appear.
The steps that work
- Control blood sugar if you have diabetes
- Keep blood pressure in target
- Avoid long-term regular use of NSAID painkillers
- Stay adequately hydrated
- Do not smoke, and limit alcohol
- Stay active and maintain a healthy weight
Get screened
With diabetes, high blood pressure, a family history of kidney disease, or age over 60, request an annual eGFR and urine albumin test even if you feel well.
Frequently asked questions
Can kidney disease be prevented completely?
Not always, particularly inherited forms, but controlling diabetes and blood pressure prevents or delays most cases.
Does drinking more water protect the kidneys?
Staying hydrated helps prevent stones and some acute injury, but it cannot reverse established damage.
