You cannot prevent every cause of kidney disease. You can take steps to lower your risk and find problems early, particularly if you have high blood pressure, diabetes, heart disease, or a family history of kidney disease.
Kidney disease often causes no symptoms at first. That makes prevention a combination of everyday habits, care for conditions that affect the kidneys, and the right tests—not waiting until you feel unwell.

1. Know your personal risk
Tell your healthcare professional if you have diabetes, high blood pressure, heart disease, or a close relative with kidney disease. These details help them decide whether you need testing and how often.
If you already have an abnormal kidney result, ask what it means rather than assuming you can prevent a condition that may already be present. Our guide to kidney disease symptoms, causes, and treatment is a useful starting point.
2. Check your blood pressure
High blood pressure can damage the kidneys over time. It may not cause obvious symptoms, so have it measured as advised. If you have been given a target or asked to check it at home, keep a record to discuss at appointments.
Food choices, activity, and prescribed medicines can all help. Do not stop blood pressure medicine because a reading improves; ask your prescriber whether your treatment needs changing.
3. Manage diabetes if you have it
High blood sugar can harm the kidneys. Work with your diabetes care team on monitoring, food choices, activity, and medication. Ask about kidney testing even if you feel well.
If you have both diabetes and high blood pressure, managing both is especially useful for protecting kidney health.
4. Eat less sodium
Many packaged and restaurant foods contain more sodium than you might expect. Compare labels on soups, sauces, snacks, and ready-made meals. Cooking more often with garlic, onion, lemon, and spices can help you use less salt without losing flavor.
You can start with the foods you eat most frequently. Our article on reducing sodium and phosphorus in foods has practical label-reading tips.
5. Choose an eating pattern you can maintain
Build meals around a variety of foods that support your overall health. If you have diabetes, your food plan should also help you manage blood sugar. If kidney disease has already been diagnosed, ask whether you need individualized advice about protein, potassium, phosphorus, or fluids.
A restrictive “kidney cleanse” diet is not needed to prevent CKD. For people who do have CKD, food restrictions should reflect their lab results and treatment.
Looking for a structured daily routine? Review the Kidney Health program. Check any recommended food restrictions with your doctor or renal dietitian.
6. Be physically active
Regular movement can help with blood pressure, blood sugar, weight, and heart health. Walking is one option; choose activities you can enjoy and keep doing.
If you have a medical condition or have been inactive, ask your healthcare professional how to begin safely. You do not need a special “kidney exercise” to gain the wider benefits of being active.
7. Check pain medicines before using them regularly
Over-the-counter medicines deserve as much attention as prescriptions. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen can harm the kidneys in some situations, especially with prolonged use or dehydration.
Ask a clinician or pharmacist which pain or cold medicines are suitable for you. Keep a list of all medicines you take so potential problems are easier to spot.
8. Have a plan for illness and dehydration
Vomiting, diarrhea, fever, and poor fluid intake can increase the risk of dehydration. Ask your healthcare team in advance when to seek help and whether illness should change how you take any prescribed medicine. Follow their instructions rather than changing a dose on your own.
If you have been told to limit fluids because of kidney or heart problems, do not follow a general instruction to drink large amounts of water.
9. Avoid smoking and be cautious with supplements
If you smoke, getting support to quit can benefit your blood vessels, heart, and kidneys. Tell your healthcare team about vitamins, powders, and herbal products too.
A label saying “natural kidney support” does not establish that a product prevents kidney disease or is safe for someone who has it. Check the exact ingredients with a healthcare professional before use. Our guide to natural remedies for kidney disease explains the distinction between supportive habits and cure claims.
10. Get kidney tests when your risk calls for them
Two common checks are a blood test used to calculate estimated glomerular filtration rate (eGFR) and a urine albumin-to-creatinine ratio (uACR). Together they provide information about filtering function and possible kidney damage.
Ask your healthcare professional whether you need these tests and when to repeat them. Finding a problem early gives you the chance to address its cause and monitor whether your plan is working.
A simple way to get started
At your next appointment, ask: “Am I at increased risk of kidney disease, and do I need blood and urine tests?” Bring a list of your medicines and supplements. Then choose one habit you can act on this week, such as checking your blood pressure, comparing sodium labels, or planning regular walks.
Small, repeatable steps are easier to maintain than a sudden overhaul. Follow up on your results so you know whether anything else needs attention.
Frequently asked questions
Can kidney disease always be prevented?
No. Some causes are outside your control. Managing risk factors and detecting problems early can still make a meaningful difference.
Will I notice symptoms if my kidneys are damaged?
Not necessarily. Early CKD often has no noticeable symptoms. Testing matters if you have risk factors.
Should I drink extra water to prevent kidney disease?
Stay hydrated according to your needs, but more water is not automatically better. Ask for personal guidance if you have kidney or heart disease or a fluid restriction.
Can supplements prevent kidney disease?
No supplement should be assumed to prevent CKD. Some products may be harmful or interact with medicines. Discuss the exact product with your healthcare professional before taking it.
The takeaway
The strongest prevention plan begins with your own risks. Manage blood pressure and diabetes, eat with less excess sodium, stay active, use medicines carefully, and ask when you should have kidney blood and urine tests. If a problem is found, early follow-up gives you more opportunity to protect your kidney health.
