🩺 Why Kidney Health Declines With Age
After age 40, kidney function decreases by about 1% per year. By the time someone reaches their 70s or 80s, filtration capacity may be half of what it was in youth.
This isn’t just “normal aging”—it’s a vulnerability that can be worsened by:
High blood pressure (damages delicate kidney blood vessels)
Diabetes (high blood sugar scars filtering units)
Chronic dehydration (reduces blood flow to kidneys)
Long-term use of NSAIDs (ibuprofen, naproxen)
High-sodium diets (forces kidneys to work harder)
Smoking and excessive alcohol (reduces blood flow)
⚠️ Key fact: Early kidney disease has no symptoms. You won’t feel pain or fatigue until significant damage has already occurred.

🔍 Silent Warning Signs (Often Missed)
Because kidneys are so resilient, problems go unnoticed until 30–50% of function is lost. Watch for subtle clues:
Foamy or bubbly urine (protein leakage)
Swelling in ankles, feet, or hands (fluid retention)
