Learning objectives
- Explain progressive loss of kidney function.
- Explain quiet early disease and later symptoms.
Progressive loss of kidney function
Chronic kidney disease usually develops through a slow decline over months or years. Kidneys remove waste and excess water; declining function allows these to accumulate. Diabetes and high blood pressure are common causes. Other contributors include inherited abnormalities, autoimmune disorders, infection, stones, injury, certain medicines, and backward urine flow. Kidney disease also affects blood counts, vitamin D, mineral balance, and bone health. Function can decline so gradually that symptoms go unnoticed until disease is advanced.
Quiet early disease and later symptoms
Function can decline so gradually that symptoms go unnoticed until disease is advanced. Fatigue, poor appetite, nausea, itching, dry skin, and weight loss can resemble other illnesses. Worsening disease may cause swelling, breathlessness, vomiting, cramps, numbness, or concentration difficulty. Bone pain and sleep problems can also occur. Symptoms alone cannot reliably indicate how well the kidneys are filtering blood. Urinalysis can reveal protein or other abnormalities before symptoms appear.
Key concepts
- Progressive loss of kidney function
- Chronic kidney disease usually develops through a slow decline over months or years.
- Quiet early disease and later symptoms
- Function can decline so gradually that symptoms go unnoticed until disease is advanced.
- Urine protein and blood measurements
- Urinalysis can reveal protein or other abnormalities before symptoms appear.
- Slowing damage and replacing lost function
- Controlling pressure and glucose can slow further damage.
