Nobody ever explained what kidney disease looks like. Can you break it down?

CKD stages are based on your eGFR, which measures how well your kidneys filter waste.
Key Takeaways

• Stages 1–2: Often no symptoms; early monitoring and lifestyle changes can help.
• Stages 3a–3b: Kidney damage is more noticeable; medical and nutrition management are essential.
• Stages 4–5: Significant loss of kidney function; requires specialist care and close monitoring.
