Natural Ways to Prevent Kidney Failure in the Elderly

The prevalence of chronic kidney disease in seniors is dramatically higher than in the general adult population, with recent estimates suggesting about 44% of adults over 65 globally have chronic kidney disease. 

CKD is common in older adults because of the combined effects of ageing itself, high rates of comorbidities such as hypertension and diabetes, and age-related structural and functional changes in the kidneys. Despite these risk factors, there are important ways to help prevent kidney failure in the elderly. Here are some of them:

Ways to Prevent Kidney Failure in the Elderly

Healthy diet

Eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins can reduce strain on the kidneys and help manage weight, blood pressure, and blood sugar. You should limit sodium (less than 2,300 mg daily), added sugars, and processed foods, which are linked to hypertension and diabetes, the main drivers of CKD. 

Regular physical activity

Moderate, regular exercise such as walking, swimming, or gentle yoga supports cardiovascular health, helps control weight, and lowers blood pressure, reducing kidney failure in the elderly. 

Adequate hydration

Drinking enough water helps the kidneys filter waste and toxins efficiently. Most seniors should aim for 6–8 cups (1.5–2 litres) of fluids daily, adjusted for individual health needs, climate, and activity level. Proper hydration is especially important for those with a history of kidney stones or who take medications that affect fluid balance. However, people with advanced CKD or heart failure should consult their doctor, as fluid intake may need to be restricted.

Avoiding nephrotoxic substances

Seniors should use over-the-counter pain medications (especially NSAIDs like ibuprofen and naproxen) sparingly, as these can harm kidney function over time. Smoking and excessive alcohol consumption should also be avoided, as both can damage blood vessels and reduce kidney blood flow. 

Improving kidney health

Maintaining healthy kidneys is essential for your well-being, as these organs perform crucial tasks such as filtering waste from your blood and producing important hormones.

If you believe you may be at risk for kidney failure, it’s important to partner with your doctor to monitor for any early signs of declining kidney function.
