How can we maintain kidney health? 3.
What dietary restrictions should we follow? 4.
Can you recommend a hospital and physician for consultation? I am very concerned about these issues! Thank you for your help.

Dr. Lin Wenxu reply Urology

The assessment of kidney function should be based on blood tests (creatinine levels) for a more objective evaluation, rather than relying on size alone (Note: Of course, kidney function deterioration may lead to kidney atrophy).
Regarding kidney maintenance and dietary aspects, I personally believe it is important to minimize the burden on the kidneys, such as following a low-protein, low-sodium diet, avoiding unnecessary medications, and managing conditions that can affect kidney function, such as diabetes and urinary stones.
It is also advisable to stay well-hydrated.
For medical consultation, it is recommended to visit the nephrology outpatient department at various hospitals; at our institution, you can consult with Dr.
Lyu Yuan-san.
Thank you!

More Info

Preventing kidney atrophy, especially in patients with existing kidney disease, requires a multifaceted approach that includes medical management, dietary modifications, and lifestyle changes. Here’s a comprehensive guide to help you understand how to care for your mother’s kidneys and prevent further deterioration.

1. Understanding Kidney Atrophy
Kidney atrophy, or shrinkage of the kidneys, can occur due to various factors, including chronic kidney disease (CKD), hypertension, diabetes, and other underlying health conditions. It’s crucial to identify and manage the root causes of kidney damage. Regular consultations with a nephrologist (kidney specialist) are essential for monitoring kidney function and adjusting treatment plans as necessary.

2. Preventing Further Atrophy
To prevent further kidney atrophy, consider the following strategies:
- Control Blood Pressure and Blood Sugar: High blood pressure and diabetes are significant contributors to kidney damage. Medications may be necessary to keep these levels within target ranges. Regular monitoring is crucial.

- Avoid Nephrotoxic Substances: Certain medications and substances can harm the kidneys. Non-steroidal anti-inflammatory drugs (NSAIDs), some antibiotics, and contrast dyes used in imaging studies should be used cautiously and under medical supervision.

- Stay Hydrated: Adequate hydration is vital for kidney health. However, if your mother has fluid restrictions due to her condition, consult her healthcare provider for personalized advice.

3. Dietary Recommendations
Diet plays a crucial role in managing kidney health. Here are some dietary guidelines:
- Limit Protein Intake: Reducing protein consumption can decrease the workload on the kidneys. A dietitian can help determine the appropriate amount of protein based on her kidney function and overall health.

- Control Sodium Intake: High sodium levels can lead to hypertension and fluid retention. Aim for a low-sodium diet by avoiding processed foods, canned soups, and adding minimal salt to meals.

- Monitor Phosphorus and Potassium: Foods high in phosphorus (like dairy products, nuts, and whole grains) and potassium (such as bananas, oranges, and potatoes) may need to be limited, especially if kidney function is significantly impaired.
- Focus on Heart-Healthy Foods: Incorporate fruits, vegetables, whole grains, and healthy fats (like olive oil) to support overall health and reduce cardiovascular risks.

- Stay Away from Processed Foods: Processed foods often contain high levels of sodium, phosphorus additives, and unhealthy fats, which can exacerbate kidney issues.

4. Lifestyle Modifications
In addition to dietary changes, certain lifestyle modifications can support kidney health:
- Regular Exercise: Encourage your mother to engage in regular physical activity, as it can help manage weight, blood pressure, and overall health. Activities like walking, swimming, or yoga can be beneficial.

- Avoid Smoking and Limit Alcohol: Smoking can worsen kidney function, and excessive alcohol can lead to dehydration and other health issues.

- Stress Management: Chronic stress can negatively impact health. Techniques such as meditation, deep breathing exercises, or gentle yoga can help manage stress levels.

5. Seeking Medical Guidance
Finding a reputable hospital and nephrologist is crucial for ongoing care. Look for hospitals with specialized kidney care programs and nephrologists who have experience treating patients with kidney atrophy and chronic kidney disease. You can ask for referrals from your primary care physician or search for nephrology specialists in your area through medical directories.

Conclusion
Managing kidney health, especially in the context of atrophy, requires a comprehensive approach that includes medical management, dietary adjustments, and lifestyle changes. Regular follow-ups with healthcare providers, including nephrologists and dietitians, are essential for tailoring a plan that meets your mother’s specific needs. By taking proactive steps, you can help support her kidney health and overall well-being.
