Stages of Chronic Kidney Disease (CKD)

 Chronic Kidney Disease (CKD) is a progressive condition characterized by the gradual loss of kidney function over time. Understanding the stages of CKD is crucial for effective management and treatment, as early detection can significantly slow the progression of the disease. CKD is typically divided into five stages based on the glomerular filtration rate (GFR), which measures how well the kidneys are filtering waste from the blood.Having an eGFR less than 60 and/or a uACR higher than 30 for three months or more is a sign you may have kidney disease.

Chronic Kidney Disease (CKD



Stage 1 CKD

eGFR 90 or higher and kidney damage
(e.g. uACR 30 or higher) for 3 months or more.

Symptoms:

  • Often asymptomatic
  • Possible signs of kidney damage, such as blood or protein in the urine

Management:

  • Monitor kidney function regularly
  • Manage underlying conditions (e.g., hypertension, diabetes)
  • Adopt a kidney-friendly lifestyle, including a balanced diet and regular exercise


Stage 2 CKD

eGFR 60-89 and kidney damage
(e.g. uACR 30 or higher) for 3 months or more.

Symptoms:

  • Generally asymptomatic
  • Possible signs of kidney damage, similar to Stage 1

Management:

  • Continue regular monitoring of kidney function
  • Control blood pressure and blood sugar levels
  • Maintain a healthy lifestyle and diet

Stage 3: Moderately Decreased GFR

Stage 3 CKD is divided into two sub-stages:

Stage 3a CKD

Mild to moderate loss of kidney function
(eGFR 45-59 for 3 months or more)


Stage 3b CKD

Moderate to severe loss of kidney function
(eGFR 30-44 for 3 months or more)

Symptoms:

  • Fatigue
  • Swelling in hands and feet
  • Changes in urine color or frequency
  • Back pain

Management:

  • More frequent monitoring of kidney function
  • Possible referral to a nephrologist
  • Manage symptoms and complications, such as anemia and bone disease
  • Dietary modifications to reduce kidney workload

Stage 4 CKD

Severe loss of kidney function
(eGFR 15-29 for 3 months or more)

Symptoms:

  • More pronounced symptoms such as severe fatigue, swelling, and changes in urination
  • Nausea and vomiting
  • Loss of appetite
  • Difficulty concentrating

Management:

  • Close monitoring by a nephrologist
  • Prepare for possible dialysis or kidney transplant
  • Manage symptoms and complications aggressively
  • Further dietary restrictions to limit potassium, phosphorus, and sodium intake

Stage 5 CKD

Kidney failure
(eGFR less than 15 for 3 months or more)
or you are on dialysis

Symptoms:

  • Severe symptoms including persistent nausea, vomiting, fatigue, and swelling
  • Itching
  • Muscle cramps
  • Breathlessness

Management:

  • Initiation of dialysis or consideration of a kidney transplant
  • Comprehensive symptom management and palliative care if necessary
  • Continuous monitoring and support from a healthcare team

Conclusion

Chronic Kidney Disease is a serious condition that requires early detection and consistent management to slow its progression. Understanding the different stages of CKD helps in tailoring treatment plans and improving patient outcomes. Regular check-ups, lifestyle modifications, and adherence to medical advice are essential for managing CKD effectively.
