How to Manage Uric Acid Levels with Kidney Disease

Uric acid is a natural waste product that forms when the body breaks down substances called purines, which are found in many foods. Normally, uric acid is filtered out by the kidneys and excreted in urine. However, for people with chronic kidney disease (CKD), the kidneys may not be able to remove uric acid efficiently, leading to high levels in the blood.

Elevated uric acid can lead to gout, a painful form of arthritis that causes inflammation in the joints. People with CKD are at increased risk of developing both gout and hyperuricemia (high uric acid levels), making diet and lifestyle management critical.

Why Managing Uric Acid Matters for CKD

When uric acid builds up in the blood, it can:

• Trigger gout attacks
• Increase joint pain and inflammation
• Contribute to kidney stone formation
• Accelerate kidney damage in those with existing CKD

The good news is that making smart dietary choices can help lower uric acid levels naturally and reduce the risk of complications.

Diet Tips to Lower Uric Acid for People with Kidney Disease

1. Limit High-Purine Foods

Purines are broken down into uric acid in the body. Reducing your intake of high-purine foods can help prevent excess uric acid buildup.

Foods to limit or avoid:

• Organ meats (liver, kidney)
• Anchovies, sardines, herring
• Red meat and game meats
• Shellfish
• Processed meats (bacon, sausages)

2. Eat More Fruits and Vegetables

Fruits and vegetables are naturally low in purines and high in antioxidants, which can help reduce inflammation.

Aim for:

• At least 5 servings per day
• Colourful, low-potassium options if advised (e.g., apples, berries, carrots, zucchini)

3. Stay Well-Hydrated

Drinking plenty of water helps flush uric acid out of your system and supports healthy kidney function.

• Goal: At least 6–8 glasses of water per day, unless on a fluid restriction
• Avoid sugary soft drinks and sweetened juices, which can raise uric acid levels

4. Limit or Avoid Alcohol

Alcohol, especially beer and spirits, can increase uric acid production and lead to dehydration, worsening symptoms.

• If alcohol is allowed by your doctor, limit intake and drink water alongside it

5. Maintain a Healthy Weight

Being overweight increases the body’s uric acid levels and makes it harder for the kidneys to clear waste effectively.

• Focus on balanced meals and gentle exercise
• Avoid crash diets or fasting, which may temporarily raise uric acid

Work With a Renal Dietitian

Managing uric acid levels becomes more complex when you're also managing chronic kidney disease. A registered renal dietitian can help you:

• Create a personalized low-purine meal plan
• Adjust your diet based on potassium, phosphate, and fluid needs
• Identify foods that support your unique kidney health profile

Treatment Beyond Diet

While diet plays a major role, some people with CKD may still require medication to lower uric acid levels. Your doctor may recommend regular monitoring and blood tests to ensure your levels stay within a safe range.

Conclusion

Managing uric acid through diet, hydration, and lifestyle changes can help reduce the risk of gout and kidney complications—especially for people with CKD. Avoid high-purine foods, stay hydrated, maintain a healthy weight, and work with a healthcare provider to stay on track.
