Chronic kidney disease is classified into five stages based on the level of glomerular filtration rate, according to medical guidelines. The kidneys can function at reduced capacity for years before symptoms such as fatigue or swelling prompt a doctor visit, and significant nephron loss has typically occurred by that point.
Standard screening using estimated GFR flags a problem only when function drops below 60 mL/min/1.73m², meaning a person can lose substantial kidney function without clinical warning, according to the classification system. Because nephrons cannot be replaced after they are lost, early detection is critical but rarely achieved.
Researchers identified high blood pressure, elevated blood sugar, obesity and smoking as the main modifiable factors driving the global surge in chronic kidney disease. High blood pressure damages the delicate blood vessels inside the kidney's filtering units, while elevated blood sugar from insulin resistance accelerates damage through inflammation and oxidative stress, according to scientific literature.
The condition is closely linked to cardiovascular disease. Chronic kidney disease and cardiovascular disease share common etiologies such as diabetes and hypertension, and patients with chronic kidney disease are more likely to die from cardiovascular causes than to develop kidney failure, according to researchers. Addressing blood pressure and blood sugar directly protects kidney function....<<<Read More>>>...
