    The Stages of Chronic Kidney Disease

    Reviewed by Medical Contributor Dinesh K. Chatoth, MD, FASN on February 1, 2021.
    Chronic kidney disease (CKD) is divided into 5 stages based on levels of kidney function. Your CKD stage is determined by calculating your estimated glomerular filtration rate (eGFR)—which is a measurement of how well your kidneys are cleaning your blood. The goal at each of the CKD stages is to take the best care and control of your health, so you can help slow the progression of CKD and keep your kidneys working as long as possible.

    5 STAGES OF KIDNEY DISEASE

     
    Stage 1 CKD: Mild kidney damage, eGFR 90 or higher 
    Stage 2 CKD: Mild loss of kidney function, eGFR 60-89 
    Stage 3a & 3b CKD: Mild to severe loss of kidney function, eGFR 30-59 
    Stage 4 CKD: Severe loss of kidney function, eGFR 15-29 
    Stage 5 CKD: Kidney failure or close to failure, eGFR less than 15

    Kidney disease is a progressive disease, meaning that your kidney function may decline over time. However, being diagnosed with early stage CKD doesn’t necessarily mean that you’ll progress to later stages. Getting tested and knowing your CKD stage can help you work with your doctor to protect your kidney health.

    Understanding the CKD stages

    Why you need a kidney doctor
    A nephrologist, also known as a kidney doctor, is the most qualified doctor to help you manage kidney disease. Ask your doctor for a referral to a nephrologist when your eGFR is between 30-44.

    Knowing your GFR and taking action

    Being aware of your GFR and what stage of kidney disease you’re in will help determine your care plan. Each person experiences kidney disease differently and the amount of time spent in the CKD stages can vary. Getting an early CKD diagnosis and taking early action is important. To help slow progression, start working with your doctor and taking steps to look after your health as soon as possible. Meeting regularly with your doctor to monitor your health can help you take control of your choices and do everything you can to manage your kidney health—so you can feel your best.
