Living with Stage 4 Kidney Disease: What Patients Need to Know

If you've been diagnosed with stage 4 kidney disease, you're facing a serious health challenge that requires immediate attention and comprehensive care. This advanced stage of chronic kidney disease (CKD) means your kidneys are severely damaged, but with proper management, you can still maintain quality of life and possibly slow disease progression.

What Is Stage 4 Kidney Disease?

Stage 4 kidney disease means your kidneys are severely damaged and functioning at only 15-29% of their normal capacity. At this stage, waste products build up in your blood, causing more noticeable symptoms and health complications.

Your doctor measures kidney function using a blood test called eGFR (estimated glomerular filtration rate). In stage 4 kidney disease, your eGFR falls between 15-29 ml/min, compared to 90 or higher in healthy kidneys.

Common Symptoms of Stage 4 Kidney Disease

As kidney function declines to stage 4, symptoms typically become more noticeable:

• Severe fatigue and weakness
• Persistent nausea or vomiting
• Loss of appetite
• Trouble sleeping
• Changes in how much you urinate
• Swelling in hands, feet, ankles, or face
• Muscle cramps and twitches
• Itchy skin
• Shortness of breath
• Bad taste in mouth or metallic taste
• Confusion or trouble concentrating

Health Complications in Stage 4 Kidney Disease

With severely reduced kidney function, several serious health problems can develop:

• High blood pressure that's difficult to control
• Anemia (low red blood cell count)
• Bone disease from mineral imbalances
• Heart problems
• Fluid buildup in lungs and other tissues
• Elevated potassium levels in the blood
• Metabolic acidosis (too much acid in the body)

Diagnosing Stage 4 Kidney Disease

To confirm stage 4 kidney disease, your doctor will order:

• Blood tests to measure kidney function (eGFR, creatinine, BUN)
• Urine tests to check for protein and other abnormalities
• Imaging tests like ultrasound or CT scan
• Sometimes additional tests to identify the underlying cause

Treatment Options for Stage 4 Kidney Disease

While stage 4 kidney disease can't be reversed, treatment focuses on slowing progression and managing complications:

Medical Management

• Blood pressure medications (especially ACE inhibitors or ARBs)
• Medications to control phosphorus levels
• Vitamin D supplements
• Erythropoietin to treat anemia
• Sodium bicarbonate for metabolic acidosis
• Diuretics to reduce fluid buildup

Dietary Changes

• Working with a renal dietitian is essential
• Limiting protein intake carefully
• Restricting sodium, potassium, and phosphorus
• Controlling fluid intake
• Following a heart-healthy diet
• Possibly taking special renal vitamins

Lifestyle Modifications

• Avoiding smoking and alcohol
• Getting appropriate exercise (with doctor approval)
• Managing stress
• Getting adequate rest
• Avoiding NSAIDs and other kidney-damaging medications

Preparing for Stage 5 Kidney Disease

At stage 4, it's important to start planning for the possibility of kidney failure (stage 5):

Learning About Treatment Options

• Hemodialysis (in-center or home)
• Peritoneal dialysis
• Kidney transplantation
• Conservative management (non-dialysis care)

Planning for Access

If dialysis may be needed in the future, your doctor might recommend creating an access site in advance:

• Arteriovenous (AV) fistula or graft for hemodialysis
• Peritoneal dialysis catheter placement

Transplant Evaluation

• Getting on the transplant waiting list
• Exploring living donor options
• Completing necessary medical evaluations

Living Well with Stage 4 Kidney Disease

Despite the challenges, many people maintain good quality of life with stage 4 kidney disease by:

• Taking all medications as prescribed
• Keeping all medical appointments
• Following dietary guidelines closely
• Monitoring blood pressure and symptoms
• Managing other health conditions like diabetes
• Joining support groups
• Staying mentally active
• Maintaining social connections

When to Call Your Doctor

Contact your healthcare provider immediately if you experience:

• Severe shortness of breath
• Chest pain
• Significant increase in swelling
• Severe nausea or vomiting
• Confusion or extreme fatigue
• Inability to keep medications down

The Importance of Your Healthcare Team

At stage 4 kidney disease, your care team will likely include:

• Nephrologist (kidney specialist)
• Primary care doctor
• Renal dietitian
• Nurse coordinator
• Social worker
• Possibly other specialists (cardiologist, endocrinologist)

Hope for the Future

While stage 4 kidney disease is serious, many people successfully manage their condition for years with proper care. New treatments continue to emerge, and kidney transplantation offers excellent outcomes for eligible patients.

Remember that each person's journey with kidney disease is unique. Working closely with your healthcare team and following your treatment plan gives you the best chance to maintain your health and quality of life with stage 4 kidney disease.

By taking control of your kidney health now, you can face the future with knowledge, support, and hope.
