8 Expert-Backed Ways to Protect Your Kidney Health

Your kidneys work tirelessly, filtering about 200 quarts of fluid every day to remove waste and toxins from your body. Despite their critical role, kidney health is often overlooked until there is a problem. The good news is that many forms of kidney disease are preventable.

By adopting a few healthy habits, you can significantly reduce your risk of kidney damage. Here are eight expert-backed ways to protect your kidneys and keep them functioning optimally for years to come.

1. Stay Well Hydrated (But Don't Overdo It)

Drinking enough water helps your kidneys clear sodium, urea, and toxins from the body, which lowers your risk of developing chronic kidney disease and kidney stones. Aim for about 8 glasses of water a day, but remember that your exact needs depend on your age, climate, and activity level. There is no need to aggressively over-hydrate; simply drinking to thirst and keeping your urine a pale yellow color is a good benchmark.

2. Control Your Blood Pressure

High blood pressure is the second leading cause of kidney failure. It damages the delicate blood vessels inside the kidneys, reducing their ability to filter waste. Have your blood pressure checked regularly. If it is high, work with your doctor to lower it through lifestyle changes, diet, and medication if necessary.

3. Manage Your Blood Sugar

Diabetes is the number one cause of kidney damage. When your blood cells cannot use the glucose in your blood, your kidneys are forced to work overtime to filter the excess sugar. Over the years, this strain causes life-threatening damage. If you have diabetes, strict blood sugar control is the most effective way to protect your kidneys.

4. Eat a Kidney-Friendly Diet

A balanced diet reduces the workload on your kidneys. Focus on fresh fruits, vegetables, whole grains, and lean proteins. Most importantly, limit your sodium intake. High sodium raises blood pressure and forces the kidneys to work harder. Avoid highly processed foods, canned soups, and fast food, which are typically loaded with hidden salt.

5. Be Cautious with Over-the-Counter Pills

Regularly taking nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen for chronic pain can cause severe kidney damage over time. While these medications are safe for occasional use, relying on them daily can restrict blood flow to the kidneys. Always consult your doctor for alternative pain management if you have chronic pain.

6. Quit Smoking and Limit Alcohol

Smoking damages blood vessels throughout your body, including those in your kidneys, decreasing blood flow and exacerbating high blood pressure. Quitting smoking is one of the best things you can do for your overall health. Additionally, excessive alcohol consumption can cause changes in the function of the kidneys and make them less able to filter your blood.

7. Keep Active and Fit

Regular exercise helps maintain an ideal body weight, reduces blood pressure, and lowers the risk of Chronic Kidney Disease. You don't need to run marathons; engaging in moderate activities like walking, cycling, or swimming for 30 minutes a day can yield significant protective benefits for your kidneys.

8. Get Regular Screenings if You Are at Risk

If you have diabetes, high blood pressure, obesity, or a family history of kidney disease, you are at a higher risk for developing kidney issues. Ask your primary care doctor for regular kidney function screenings, which include a simple blood test (to check eGFR) and a urine test (to check for protein). Early detection is the key to preventing irreversible damage.
