10 Tips to Protect Your Kidneys and Prevent Kidney Disease

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.

10. Limit Alcohol

Excessive alcohol raises blood pressure and damages kidneys over time.
