A stage 3b kidney disease care plan is a structured approach for managing chronic kidney disease (CKD), monitoring kidney function, reducing complications, and protecting the kidney function that remains.

Stage 3b CKD generally corresponds to an estimated glomerular filtration rate (eGFR) of 30–44 mL/min/1.73 m². At this stage, kidney function is significantly reduced, but many people can continue managing their condition without dialysis for a considerable period, depending on the underlying cause, rate of progression, other health conditions, and response to treatment.

A good care plan should not focus on one number or one medication. Instead, it should bring together medical treatment, laboratory monitoring, nutrition, blood pressure management, lifestyle habits, and regular communication with a healthcare team.

Treatment plans should be individualized by a qualified healthcare professional based on kidney function, laboratory results, medications, symptoms, and other health conditions.

What Is a Stage 3b Kidney Disease Care Plan?

A care plan is essentially a roadmap for managing CKD.

For someone with stage 3b kidney disease, it may include:

• Regular eGFR testing
• Urine albumin-to-creatinine ratio (UACR) monitoring
• Blood pressure management
• Diabetes management when applicable
• Medication review
• Kidney-friendly nutrition
• Sodium management
• Physical activity
• Monitoring for CKD complications
• Medication safety
• Regular follow-up with healthcare professionals
• Nephrology care when appropriate

NIDDK recommends an interdisciplinary approach to CKD management and emphasizes monitoring eGFR and UACR trends to assess progression and response to treatment.

1. Establish Your Baseline Kidney Function

The first step in a stage 3b kidney disease care plan is understanding your current kidney function.

The eGFR blood test estimates how well the kidneys filter blood. A stage 3b result is generally between 30 and 44.

However, one eGFR result does not necessarily tell you how quickly your kidney disease is progressing.

Your healthcare team may compare:

• Current eGFR
• Previous eGFR
• Serum creatinine
• UACR
• Blood pressure
• Potassium
• Bicarbonate
• Hemoglobin
• Calcium and phosphorus

Looking at trends over time can provide more useful information than focusing on one isolated laboratory result.

Why UACR Matters

The urine albumin-to-creatinine ratio measures albumin in the urine.

Albuminuria can provide important information about kidney damage and progression risk.

For this reason, your care plan should track both eGFR and UACR, rather than focusing only on creatinine.

NIDDK specifically recommends monitoring trends in both measurements when managing CKD.

2. Create a Blood Pressure Management Plan

Blood pressure control is one of the most important components of CKD management.

High blood pressure can damage the kidneys, while CKD itself can contribute to high blood pressure.

Your personal blood pressure target should be determined with your healthcare professional.

A blood pressure care plan may include:

• Taking prescribed medications consistently
• Reducing excessive sodium
• Monitoring blood pressure at home when advised
• Regular physical activity
• Maintaining appropriate weight
• Avoiding tobacco
• Getting adequate sleep

NIDDK identifies blood pressure control as a central part of CKD management.

Home Blood Pressure Monitoring

If your healthcare professional recommends checking blood pressure at home, an upper-arm blood pressure monitor can be a practical tool.

A home monitor does not treat kidney disease, but keeping a record of readings can help your healthcare team evaluate your blood pressure pattern.

Always follow the device instructions and use the cuff size appropriate for your arm.

3. Review Kidney-Protective Medications

Medication management should be an important section of your care plan.

Depending on your condition, your healthcare professional may consider medications such as:

• ACE inhibitors
• ARBs
• SGLT2 inhibitors
• Other blood pressure medications
• Diuretics
• Cholesterol-lowering medications
• Diabetes medications
• Treatments for specific CKD complications

ACE inhibitors and ARBs can be particularly important for certain people with CKD and albuminuria. NIDDK notes that these medicines may slow kidney disease progression and delay kidney failure in appropriate patients.

KDIGO 2024 also recommends SGLT2 inhibitors for certain adults with CKD, including eligible patients with eGFR levels that overlap with stage 3b CKD.

Medication selection must be individualized.

Keep an Updated Medication List

Your care plan should include a current list of:

• Prescription medications
• Over-the-counter medicines
• Vitamins
• Minerals
• Herbal products
• Dietary supplements

Kidney function can affect how some medications are processed and eliminated.

NIDDK recommends reviewing medications with healthcare professionals because doses may need to change as kidney function changes.

4. Make Medication Safety a Priority

People with stage 3b CKD need to be particularly careful about over-the-counter medications.

One important example is NSAIDs, including ibuprofen and naproxen.

NIDDK warns that NSAIDs can damage the kidneys and increase the risk of acute kidney injury, particularly in people with kidney disease, diabetes, or high blood pressure.

Before taking an over-the-counter pain reliever, cold medicine, vitamin, or supplement, ask a healthcare professional or pharmacist whether it is appropriate for your kidney function.

Do not stop a prescribed medicine without medical guidance.

5. Build an Individualized CKD Diet Plan

Nutrition is another major part of a stage 3b kidney disease care plan.

There is no single diet that is appropriate for every person with CKD.

Your dietary plan may need to consider:

• Sodium
• Protein
• Potassium
• Phosphorus
• Calories
• Fluid intake
• Diabetes
• Blood pressure
• Nutritional status

NIDDK recommends working with a dietitian who understands kidney disease to develop an individualized meal plan.

Limit Excess Sodium

NIDDK guidance commonly recommends limiting sodium to about 2,300 mg per day for many people with CKD, although individual recommendations may differ.

High-sodium foods can include:

• Processed meats
• Canned soups
• Instant noodles
• Fast food
• Salty snacks
• Packaged sauces
• Some frozen meals
• Highly salted restaurant foods

Cooking at home can make it easier to control sodium.

Get the Appropriate Amount of Protein

Protein is essential for maintaining muscle and nutrition, but excessive protein intake may not be appropriate for some people with CKD.

NIDDK describes adequate rather than excessive protein intake as part of CKD nutrition management and provides approximately 0.8 g/kg/day as a reference for many adults, while emphasizing individualized dietary care.

Do not dramatically reduce protein on your own. Your nutritional needs may be different because of age, body size, activity level, diabetes, nutritional status, or other medical conditions.

6. Use a Kidney-Friendly Meal Planning Resource

Planning low-sodium meals can be difficult, especially when you are also considering protein, potassium, phosphorus, and calories.

A low-sodium cookbook can provide practical meal ideas.

This type of product should be treated as a meal-planning resource, not as a treatment for CKD.

If your blood potassium or phosphorus is abnormal, a renal dietitian can help determine which foods should actually be limited.

7. Manage Diabetes if You Have It

Diabetes is a major cause of chronic kidney disease.

If diabetes is part of your medical history, your care plan may include monitoring:

• Blood glucose
• A1C
• eGFR
• UACR
• Blood pressure
• Cholesterol

Your healthcare professional can establish individualized glucose goals and determine which medications are appropriate.

NIDDK recommends meeting individualized blood glucose goals and monitoring kidney health as part of CKD care.

8. Monitor Potassium and Phosphorus

Stage 3b CKD can affect the body’s ability to regulate minerals.

However, this does not mean everyone with stage 3b CKD needs the same potassium or phosphorus restrictions.

Your care plan should use laboratory results to determine whether dietary changes are necessary.

If potassium is normal, unnecessarily eliminating many potassium-containing foods could make your diet less varied.

If phosphorus is elevated, your healthcare professional may recommend specific dietary adjustments.

This is another reason personalized nutritional counseling can be valuable.

9. Monitor for CKD Complications

A comprehensive care plan should include screening for complications.

Potential complications include:

• Anemia
• Electrolyte abnormalities
• Mineral and bone disorders
• Cardiovascular disease
• Malnutrition
• Fluid-related problems

NIDDK identifies cardiovascular disease, anemia, malnutrition, and mineral and bone disorders among important CKD complications.

Depending on your situation, your healthcare team may order blood tests to monitor hemoglobin, iron status, potassium, bicarbonate, calcium, phosphorus, and other markers.

10. Build a Physical Activity Routine

Physical activity can support cardiovascular health, blood pressure management, physical function, and overall well-being.

NIDDK recommends making physical activity part of CKD management while considering individual health status.

Depending on your condition, activities may include:

• Walking
• Cycling
• Swimming
• Light resistance exercises
• Other activities approved by your healthcare professional

If you have not been active recently, discuss an appropriate starting level with your healthcare team.

11. Focus on Sleep, Smoking, and Stress

Kidney care extends beyond laboratory results.

NIDDK includes adequate sleep, smoking cessation, healthy weight management, and healthy stress management among important CKD lifestyle measures.

Your care plan might therefore include goals such as:

• Establishing a consistent sleep schedule
• Avoiding tobacco
• Finding healthy ways to manage stress
• Maintaining appropriate physical activity
• Following your individualized meal plan

These habits support overall health and can complement medical treatment.

12. Schedule Regular Follow-Up Visits

A stage 3b kidney disease care plan should specify when you will have follow-up appointments and laboratory testing.

At appointments, consider asking:

• Has my eGFR changed?
• What is my UACR?
• Has my UACR improved or increased?
• Is my blood pressure controlled?
• Are my medications still appropriate?
• Are my potassium and bicarbonate levels normal?
• Do I need a dietitian?
• Should I see a nephrologist?
• What symptoms should prompt an earlier appointment?

NIDDK specifically encourages people with CKD to ask their healthcare providers about GFR, urine albumin, blood pressure, medication changes, diet, and nephrology referral.

13. Know When Nephrology Care May Be Helpful

A nephrologist specializes in kidney disease.

Depending on the cause and progression of CKD, nephrology care may be helpful for people with stage 3b CKD, particularly when there are complex treatment decisions, substantial albuminuria, difficult-to-control blood pressure, complications, or a concerning decline in kidney function.

NIDDK notes that referrals to a nephrologist may benefit people with CKD because of the condition’s complexity.

Example Stage 3b Kidney Disease Care Plan

A personalized plan may look something like this:

Daily

• Take medications exactly as prescribed.
• Follow your individualized diet.
• Avoid unapproved NSAIDs and supplements.
• Stay physically active according to your healthcare plan.
• Monitor blood pressure if instructed.

Weekly

• Review blood pressure readings.
• Check whether you are following your nutrition plan.
• Keep your medication list updated.

At medical visits

• Review eGFR.
• Review UACR.
• Discuss blood pressure.
• Review medications.
• Check relevant laboratory tests.
• Discuss symptoms or new concerns.

Periodically

• Review your overall CKD progression.
• Reassess your nutrition plan.
• Evaluate cardiovascular risk.
• Consider nephrology referral when appropriate.

This is an example for educational purposes. Your actual care plan should be created with your healthcare team.

Frequently Asked Questions

What should a stage 3b kidney disease care plan include?

A comprehensive plan may include eGFR and UACR monitoring, blood pressure management, medication review, diabetes management when applicable, individualized nutrition, physical activity, medication safety, and monitoring for CKD complications.

What should I eat with stage 3b kidney disease?

Many people with CKD are advised to reduce excessive sodium and avoid excessive protein intake. Potassium and phosphorus restrictions should generally depend on laboratory results and individualized medical advice.

How often should kidney function be checked?

The appropriate testing frequency depends on your kidney function, albuminuria, rate of progression, medications, and other health conditions. Your healthcare professional should determine the schedule.

Should I monitor blood pressure at home?

If your healthcare professional recommends home monitoring, an upper-arm blood pressure monitor can help you keep a record of readings. Those readings can be reviewed during medical appointments.

Can stage 3b CKD be reversed?

Established chronic kidney damage generally cannot simply be reversed with a food, supplement, or online program. However, some temporary factors that worsen kidney function may be treatable. The goal is generally to identify the cause and protect remaining kidney function.

When should I see a nephrologist?

A nephrologist may be particularly useful when kidney function is declining, the cause is unclear, treatment is complex, significant albuminuria is present, or CKD complications develop.

Final Thoughts

A well-organized stage 3b kidney disease care plan can help turn CKD management into a series of practical, measurable steps.

The core elements include monitoring eGFR and UACR, controlling blood pressure, managing diabetes when present, taking appropriate medications, following an individualized kidney-friendly diet, avoiding potentially harmful medicines, staying physically active, and monitoring complications.

The goal is not to find one product that “cures” CKD. Instead, successful long-term management involves consistent medical care and informed daily decisions.

A home blood pressure monitor can support blood pressure tracking, while a low-sodium cookbook can provide meal-planning ideas. Educational CKD resources can also help you prepare questions for your healthcare team.

Most importantly, your care plan should be personalized. Kidney function, laboratory results, medications, nutrition needs, and other medical conditions can vary considerably from one person to another.
