Managing Stage 3 Chronic Kidney Disease: Treatment and Dietary Concerns - Internal Medicine

Managing Stage 3 Chronic Kidney Disease (CKD) requires a comprehensive approach that includes both medical treatment and dietary modifications. In your father's case, being 82 years old and diagnosed with moderate CKD, it is crucial to ensure that he receives appropriate care tailored to his specific needs.


Medical Management
In Stage 3 CKD, the kidneys are moderately impaired, and the focus of treatment is to slow the progression of the disease and manage any complications. While it is common for doctors to prescribe medications to control blood pressure, diabetes, and other related conditions, the absence of a comprehensive medication plan may raise concerns. The use of uric acid-lowering medications is appropriate if your father has hyperuricemia or gout, but it is essential to monitor kidney function and other parameters regularly.

It is advisable to consult a nephrologist (kidney specialist) for a thorough evaluation. They may recommend additional medications such as ACE inhibitors or ARBs to help protect kidney function, especially if there is proteinuria (excess protein in urine). Regular blood tests to monitor kidney function (creatinine, eGFR) and electrolytes (potassium, phosphorus) are also essential.


Dietary Considerations
Diet plays a significant role in managing CKD. Here are some general dietary recommendations for Stage 3 CKD:
1. Protein Intake: While protein is essential for health, excessive protein can put additional strain on the kidneys. A moderate protein intake is usually recommended, and the exact amount should be determined by a healthcare provider or dietitian based on your father's overall health and nutritional needs.

2. Sodium: Reducing sodium intake is crucial to help control blood pressure and minimize fluid retention. Processed foods, canned goods, and restaurant meals often contain high levels of sodium, so it is best to prepare meals at home using fresh ingredients.

3. Potassium and Phosphorus: Depending on blood test results, your father's potassium and phosphorus intake may need to be monitored. Foods high in potassium (like bananas, oranges, and potatoes) and phosphorus (like dairy products, nuts, and beans) may need to be limited if levels are elevated.

4. Fluid Intake: Depending on kidney function and any signs of fluid retention, fluid intake may need to be adjusted. It is essential to follow the advice of healthcare providers regarding fluid restrictions.

5. Overall Nutrition: A well-balanced diet rich in fruits, vegetables, whole grains, and healthy fats is important. However, certain fruits and vegetables may need to be limited based on potassium content.


Alternative Treatments
Regarding the use of cassava leaves (樹薯的葉), there is limited scientific evidence supporting their effectiveness in treating kidney disease. While some traditional remedies may have anecdotal support, it is essential to approach such treatments with caution. Always consult with a healthcare provider before introducing any alternative therapies, as they may interact with prescribed medications or exacerbate kidney issues.


Conclusion
In summary, managing Stage 3 CKD involves a combination of appropriate medical treatment and dietary adjustments. It is crucial to work closely with healthcare professionals, including nephrologists and dietitians, to create a personalized care plan. Regular monitoring and adjustments based on your father's condition will help ensure the best possible outcomes. If you have concerns about his current treatment plan, seeking a second opinion or further evaluation may be beneficial.
