10 Tips to Protect Your Kidneys and Prevent Kidney Disease

Protecting your kidneys — quick answers

How can I keep my kidneys healthy?

Drink 2–3 litres of water a day, keep blood pressure below 130/80 mmHg, keep HbA1c below 7% if you have diabetes, limit salt, avoid regular painkiller (NSAID) use, do not smoke, keep a healthy weight, exercise regularly, limit alcohol and get your kidney function tested every year if you are at risk.

What is the leading cause of kidney damage?

High blood pressure is the leading cause of kidney damage, and diabetes is the second. Controlling both is the single most effective way to prevent chronic kidney disease.

Do painkillers damage the kidneys?

Yes. NSAID painkillers such as ibuprofen and diclofenac, taken regularly, damage kidney tissue. Use them sparingly and never for long periods without medical advice.

How much water should I drink for healthy kidneys?

Around 2–3 litres a day for most healthy adults helps the kidneys flush out waste. People with advanced kidney disease or heart failure may need a fluid limit, so follow your doctor's advice.

How often should kidney function be tested?

People with diabetes, hypertension or a family history of kidney disease should have a blood creatinine and urine test every year. Kidney disease is usually silent in the early stages, and these simple tests catch it before symptoms appear.

The kidneys filter about 200 litres of blood daily. Keeping them healthy is vital for overall wellbeing.

1. Stay Well Hydrated Drink 2–3 litres of water daily to help kidneys flush out waste.

2. Control Blood Pressure Hypertension is the leading cause of kidney damage. Target below 130/80 mmHg.

3. Manage Blood Sugar Diabetes is the second leading cause of kidney failure. Keep HbA1c below 7%.

4. Eat a Kidney-Friendly Diet Reduce salt, protein, potassium (in advanced disease), and phosphorus. Eat more fruits and vegetables.

5. Don't Overuse Painkillers NSAIDs (ibuprofen, diclofenac) taken regularly damage kidney tissue.

6. Quit Smoking Smoking slows blood flow to the kidneys and worsens kidney disease.

7. Maintain a Healthy Weight Obesity raises blood pressure and risk of diabetes — both kidney disease risk factors.

8. Exercise Regularly 30 minutes of moderate exercise 5 days a week benefits the kidneys.

9. Get Regular Kidney Function Tests Annual blood creatinine and urine tests if you have diabetes, hypertension, or a family history of kidney disease.
