Overview
Chronic kidney disease describes the gradual loss of kidney function. This condition affects millions globally and can progress to end-stage kidney failure, requiring dialysis or transplantation.
Symptoms
Early Stage Symptoms
- Fatigue and weakness
- Sleep problems
- Decreased urine output
- Swelling in ankles and feet
- Persistent itching
- Muscle cramps
Advanced Stage Symptoms
- Loss of appetite
- Nausea and vomiting
- Difficulty breathing
- Chest pain
- High blood pressure
- Confusion and difficulty concentrating
- Bone pain
- Dry, itchy skin
Causes
Primary Causes
- Diabetes (Type 1 and Type 2)
- High blood pressure
- Glomerulonephritis
- Polycystic kidney disease
- Recurrent kidney infections
Risk Factors
- Family history
- Advanced age
- Obesity
- Smoking
- Race (African Americans at higher risk)
- Chronic use of certain medications
Stages of CKD
Stage 1
- Normal kidney function
- Signs of kidney damage present
- GFR ≥ 90 mL/min
Stage 2
- Mild decrease in function
- GFR 60-89 mL/min
- Early kidney damage
Stage 3
- Moderate decrease
- GFR 30-59 mL/min
- Beginning of complications
Stage 4
- Severe decrease
- GFR 15-29 mL/min
- Preparation for renal replacement
Stage 5
- Kidney failure
- GFR < 15 mL/min
- Need for dialysis or transplant
