6 Evidence-Based Ways to Protect Your Kidneys
1. Control blood pressure
High blood pressure is one of the leading causes of kidney damage.
- Check your blood pressure regularly.
- Follow your healthcare provider’s treatment plan if you have hypertension.
2. Manage blood sugar
Diabetes is a major cause of chronic kidney disease.
- Keep blood glucose levels in your recommended range.
- Attend regular checkups and kidney screenings if you have diabetes.
3. Avoid unnecessary kidney stress
- Use pain medicines like NSAIDs (such as ibuprofen or naproxen) only as directed, especially if you have kidney problems.
- Tell healthcare providers about kidney disease before starting new medicines or supplements.
4. Eat a kidney-friendly diet when needed
Depending on your kidney function, recommendations may include:
- Limiting excess salt
- Eating appropriate amounts of protein
- Choosing more fresh foods and fewer highly processed foods
(Exact limits for potassium, phosphorus, and protein depend on your individual condition.)
5. Stay hydrated—but don’t overdo fluids
Adequate hydration supports normal kidney function, but people with advanced kidney disease may have fluid restrictions. Follow your clinician’s advice.
6. Maintain a healthy lifestyle
- Don’t smoke.
- Exercise regularly as tolerated.
- Maintain a healthy weight.
- Get enough sleep.
Important:
Some kidney diseases are caused by factors that cannot be completely prevented, such as genetics, autoimmune diseases, infections, or structural problems. Early detection and proper treatment can make a major difference.
Regular checks such as blood pressure measurements, urine tests, and kidney function blood tests (like eGFR and creatinine) can help identify problems early.
If someone already has kidney disease, the best steps depend on the stage of kidney disease and the cause, so personalized medical advice is important.
