Stage 4 Kidney Disease: Treatment Options and Outlook

Understanding Stage 4 Kidney Disease

Stage 4 CKD is defined by a glomerular filtration rate (GFR) between 15 and 29 mL/min/1.73 m², indicating severe kidney damage. At this stage, waste products and fluid begin to build up in the body, often leading to complications and noticeable symptoms. Patients may already be experiencing anemia, bone disease, high blood pressure, or signs of uremia.

Where Stage 4 Fits Among CKD Stages:

• Stage 1: Normal or high GFR (≥90), mild kidney damage
• Stage 2: GFR 60–89, mild loss
• Stage 3: GFR 30–59, moderate loss
• Stage 4: GFR 15–29, severe loss
• Stage 5: GFR <15, end-stage kidney disease (kidney failure)

At Stage 4, patients often work closely with a nephrologist to slow progression and make decisions about kidney replacement therapy — dialysis or transplant.

Symptoms and Complications

As kidneys lose function, symptoms tend to become more pronounced:

• Fatigue and weakness (caused by anemia due to reduced erythropoietin production).
• Swelling in the legs, ankles, and hands (fluid retention).
• Shortness of breath (from fluid buildup in lungs or anemia-related oxygen deficiency).
• Nausea, poor appetite, and weight loss.
• Itching (pruritus) due to waste buildup.
• Muscle cramps, especially at night.
• Sleep problems and trouble concentrating.
• Discoloration of skin and nails due to toxin accumulation.

These symptoms may worsen over time without intervention.

CKD Often Goes Undiagnosed—Why Early Detection Matters

Chronic kidney disease (CKD) is common but often silent. More than 1 in 7 U.S. adults—about 35.5 million people—are estimated to have CKD, yet as many as 9 in 10 adults with CKD do not know they have it. Even among those with severe CKD, about 1 in 3 remain undiagnosed.

Key facts about CKD awareness:

• Widespread prevalence: CKD affects millions, but public awareness remains low despite the health risks.
• Silent early stages: Many people show no symptoms until the disease is advanced, making regular screening critical.
• Delayed interventions: Undiagnosed CKD often means missed opportunities for early treatment, lifestyle changes, and slowing disease progression.

Routine lab testing—specifically serum creatinine and urine albumin tests—remains critical for identifying CKD early and preventing complications like kidney failure, heart disease, and anemia.

Treatment and Management Options

Management in Stage 4 aims to preserve remaining kidney function, reduce complications, and prepare for dialysis or transplant.

Medications and Medical Management

• ACE inhibitors or ARBs: Control high blood pressure and reduce protein in the urine.
• SGLT2 inhibitors: Help slow kidney damage progression, especially in patients with diabetes or proteinuric CKD.
• Phosphate binders: Reduce phosphorus levels and protect bones.
• Erythropoiesis-stimulating agents (ESAs): Treat anemia by boosting red blood cell production.
• Diuretics: Reduce swelling and help with fluid management.
• Sodium bicarbonate: Treat metabolic acidosis.

Patients must be closely monitored for changes in serum creatinine levels, potassium, phosphorus, and calcium imbalances.

Dialysis Preparation

• Dialysis isn’t always immediately needed in Stage 4, but early education and planning can improve outcomes.
• Types of dialysis:
  • Hemodialysis: Uses a machine to filter blood, often done in a center about three times per week, though home options are also available.
  • Peritoneal dialysis: Uses the abdomen’s lining as a filter; often done at home.
• Patients may need:
  • Fistula or graft placement for hemodialysis.
  • Catheter insertion for peritoneal dialysis.

Kidney Transplant Evaluation

• Referral to a transplant center can occur before dialysis is needed.
• Options include:
  • Living donor transplant (often better outcomes).
  • Deceased donor transplant (may involve wait time).

Lifestyle and Diet

• Work with a renal dietitian to follow a kidney-friendly diet:
  • Limit sodium, potassium, and phosphorus.
  • Control protein intake to reduce waste buildup.
  • Avoid processed foods and high-phosphate additives.
  • Monitor fluid intake to prevent overload.
• Maintain blood pressure below 130/80 mm Hg.
• Manage diabetes aggressively to reduce further kidney strain.
• Avoid NSAIDs (e.g., ibuprofen), which worsen kidney damage.
• Consider exercise and smoking cessation as part of overall care.

Prognosis and Life Expectancy

Stage 4 CKD is serious, but with early and consistent management, patients may delay the need for dialysis or transplant for years.

Factors Influencing Prognosis

• Adherence to treatment plans and medications.
• Presence of comorbid conditions (e.g., heart disease, diabetes).
• Access to specialist care and support resources.
• Proactive lifestyle and regular monitoring (e.g., eGFR and urine tests).

With optimal management, quality of life can remain high, and some individuals may qualify for a preemptive kidney transplant (before dialysis).

Prevention of Progression

While Stage 4 is advanced, further progression of CKD can be slowed:

• Control high blood pressure with medications and diet.
• Keep blood sugar in target range if diabetic.
• Avoid smoking and limit alcohol.
• Regular use of EGFR blood tests and urine albumin tracking.
• Manage anemia and bone disease early.
• Use phosphate binders and vitamin D analogs as prescribed.

Genetic and family history may also play a role, so inform your provider if there is a known genetic disorder or family history of kidney disease.

Support and Resources

Emotional and Practical Support

• Support groups can connect patients and families for mutual guidance.
• Self-management tools and apps (like Kidney Kitchen) help with tracking diet and labs.
• Family and friends play a critical role in encouraging adherence and emotional stability.
• Access to a nephrologist, social worker, and dietitian is key.

Tools and Services

• Ultrasounds and imaging tests may be used to track kidney size and damage.
• Kidney biopsy may be needed to determine underlying causes if not already known.
• Mental health support is important to manage depression or anxiety.

What Medicare Covers

Medicare provides broad coverage for patients with Stage 4 kidney disease, even before dialysis begins:

• Nephrology visits: Covered under Part B.
• Laboratory tests: eGFR, creatinine, and urine tests are typically covered.
• Dialysis education: Up to 6 sessions may be covered for patients with Stage 4 CKD.
• Medical Nutrition Therapy: Medicare covers dietitian visits for kidney disease patients, but a doctor’s referral is required.
• Transplant evaluation: Medicare may pay for evaluation and matching procedures.
• Dialysis (when needed)**: Hemodialysis and peritoneal dialysis are covered under Part B and Part A, depending on location of treatment.

Those approaching end-stage kidney disease (ESKD) can qualify for Medicare regardless of age, ensuring access to life-saving treatments.

Frequently Asked Questions (FAQ) About Stage 4 Kidney Disease

1. What is Stage 4 kidney disease and how serious is it?

Stage 4 chronic kidney disease (CKD) is a severe form of kidney damage where the kidneys have lost roughly 70–85% of their function, corresponding to an estimated glomerular filtration rate (eGFR) between 15 and 29 mL/min/1.73 m². At this stage, many patients begin to experience complications and must prepare for kidney replacement therapy such as dialysis or transplant.

2. Can you live a normal life with Stage 4 CKD?

While “normal” may look different for each patient, many people with Stage 4 CKD live active, fulfilling lives for years, especially when the disease is well-managed. Success depends on medication adherence, lifestyle changes, and routine monitoring, all coordinated under the care of a nephrologist and care team.

3. What are the treatment options for Stage 4 kidney disease?

Treatment includes:

• Medications (e.g., ACE inhibitors, phosphate binders, ESAs)
• Dietary modifications (kidney-friendly diet)
• Dialysis planning or transplant evaluation
• Management of underlying causes like diabetes or hypertension
• Treatment goals are to slow progression, manage symptoms, and delay kidney failure.

4. When will I need dialysis with Stage 4 CKD?

Not all patients with Stage 4 CKD require immediate dialysis. It’s usually started when eGFR falls below 15 or when symptoms of kidney failure (such as severe fluid overload, uremia, or acidosis) become unmanageable. Early planning helps ensure smoother transitions and avoids emergency dialysis.

5. What is the life expectancy for someone with Stage 4 kidney disease?

Life expectancy varies based on age, comorbid conditions (like diabetes or heart disease), treatment adherence, and whether dialysis or transplant becomes available. Many patients live 5–10 years or more after entering Stage 4, particularly when they follow medical and lifestyle recommendations.

6. What should I eat if I have Stage 4 kidney disease?

A renal diet typically includes:

• Low sodium to reduce blood pressure and swelling
• Controlled protein intake to minimize waste buildup
• Limited potassium and phosphorus to prevent heart and bone complications
• Restricted fluids (if fluid retention is present)
• Processed foods, red meats, dairy, and dark sodas are often reduced. A renal dietitian can personalize your plan based on lab results.

7. Does Medicare cover treatments for Stage 4 CKD?

Yes. Medicare often covers:

• Nephrologist visits
• Lab work (eGFR, creatinine, urine tests)
• Medical Nutrition Therapy (with a dietitian)
• Dialysis education (up to 6 sessions)
• Kidney transplant evaluations and testing
• Once diagnosed with end-stage kidney disease (Stage 5), you may qualify for Medicare regardless of age.

8. Can Stage 4 kidney disease be reversed?

No, Stage 4 CKD is not reversible. However, the progression can be slowed or stabilized with timely interventions, including blood pressure control, blood sugar management, dietary adjustments, and medication. The earlier treatment begins, the better the long-term outcomes.

9. How do I know if I’m eligible for a kidney transplant?

Eligibility depends on:

• Overall health status
• Absence of active infections or cancer
• Good heart and lung function
• Willingness to follow post-transplant care
• Your nephrologist can refer you for a transplant evaluation, where a team assesses your physical and emotional readiness. You may qualify for a preemptive transplant before starting dialysis.
