Kidney Diseases

Kidney diseases are rising faster than any other noncommunicable cause on this list, now causing 1.3 million deaths annually—a toll that matches #9 Tuberculosis but with a much steeper growth trajectory. Chronic kidney disease (CKD) affects 850 million people globally, surpassing diabetes in prevalence, yet 90% of sufferers are unaware until they lose most kidney function. Diabetes and hypertension drive 80% of cases, making this a largely avoidable crisis. Treatment costs are prohibitive, with dialysis running $50,000 to $100,000 per patient per year in developed countries, creating a stark inequality in survival rates. Early detection and blood pressure management could cut deaths by 30% within a decade.
