Your kidneys are like your body’s cleanup crew, filtering about 150 quarts of blood every day. That’s enough to fill a small swimming pool! Yet 37 million Americans live with chronic kidney disease (CKD), and many don’t even know it. Did you catch that? That’s 1 in 7 adults walking around with varying degrees of kidney damage. Let’s decode what these stages mean for you or your loved ones.
The Chronic Kidney Disease (CKD) Stages Chart below shows you how kidney function changes over time, what to expect at each stage, and key management steps to take. Use this chart as your reference point while we explore each stage in detail below. Pay special attention to the GFR numbers (that’s your kidney function score) and the recommended actions for each stage.
Breaking Down Each Stage of Kidney Disease
Stage 1: The Early Warning Signs Think of Stage 1 as your kidneys sending you a postcard. They’re still doing their main job pretty well (GFR ≥ 90 mL/min/1.73m²), but there are hints that something’s not quite right. Your doctor might spot protein in your urine or notice slight changes in your kidney structure during imaging tests.
What happens at this stage:
- Your kidneys still filter blood effectively
- You probably won’t feel any symptoms
- Regular checkups become your best friend
- Simple lifestyle changes can make a big difference
Quick Tip: This is your golden opportunity. Small changes now can lead to big rewards later.
Stage 2: A Gentle Reminder Your kidneys are now working at 60-89% capacity. Like a car showing early signs of wear, they’re still reliable but need more attention. Blood pressure often becomes a concern during this stage.
Key points about Stage 2:
- Blood tests show mild decreases in kidney function
- You might still feel normal
- Blood pressure control becomes crucial
- Diet and exercise make a real difference
Getting Active: Regular exercise at this stage isn’t just good for your heart, it helps your kidneys too.
Stage 3: Time to Get Serious This middle stage (GFR 30-59 mL/min/1.73m²) is when physical changes often become noticeable. Your body starts showing signs that your kidneys aren’t keeping up with their usual workload.
Common experiences include:
- Feeling more tired than usual
- Swelling in your hands and feet
- Changes in how often you need to urinate
- Your appetite might decrease
The Specialist Step: This is when your doctor might refer you to a kidney specialist (nephrologist).
Stage 4: All Hands on Deck With kidney function at 15-29%, Stage 4 requires careful attention. Think of it as your body’s urgent call for action. Your healthcare team will likely grow to include several specialists.
Important focus areas:
- Preparing for possible future treatments
- Strict diet modifications
- Regular monitoring of blood work
- Managing other health conditions carefully
Treatment Planning: Now’s the time to learn about all your options, including dialysis and transplant possibilities.
Stage 5: The Final Stage When kidney function drops below 15%, we call it kidney failure or end-stage renal disease. It sounds scary, but remember: people live full lives with kidney failure thanks to modern medicine.
Your options include:
- Dialysis (either at home or a center)
- Kidney transplant evaluation
- Comprehensive symptom management
- Support group participation
Living Well: Many people balance full lives with Stage 5 CKD through proper treatment.
Taking Control of Your Kidney Health

- Adjust medications as needed
- Plan for future treatment needs
- Address your concerns and questions
The Family Connection CKD affects everyone in your circle. Keep your loved ones informed about:
- Your treatment plan
- Ways they can help

Looking Forward Living with CKD means making adjustments, but it doesn’t define you. Modern medicine offers more options than ever before. Many people live decades with well-managed kidney disease.
Your Action Plan Start with these steps:
- Schedule regular checkups
- Learn your numbers (GFR, blood pressure, etc.)
- Make gradual lifestyle changes
- Build your support network
- Stay informed about treatment options
Remember, knowledge plus action equals power. Understanding your CKD stage helps you take control of your health journey. You’re not alone on this path. Millions walk it successfully every day, and with proper care and attention, you can too.
