The quiet fields of Uddanam conceal a growing health emergency. New data from an ongoing study reveals that nearly a quarter of people screened in this northeastern Andhra Pradesh region are living with kidney disease—with Kaviti mandal emerging as the epicenter of suffering.

Key facts

  • 949 of 3,897 people screened (24.35%) have kidney disease
  • 550 diagnosed with Chronic Kidney Disease (CKD)
  • 399 diagnosed with Chronic Kidney Disease of Unknown Aetiology (CKDu)
  • Study aims to screen 5,851 people across four mandals

Kaviti's Concerning Numbers

Researchers presented their interim findings to Health Minister Satya Kumar Yadav on Saturday, painting a troubling picture of renal health in the agricultural region. The numbers tell a stark story: of those diagnosed, 550 have Chronic Kidney Disease while 399 suffer from Chronic Kidney Disease of Unknown Aetiology—a mysterious form that puzzles scientists.

Kaviti mandal stands out with the highest number and proportion of cases, suggesting something in this particular area—whether environmental, occupational, or both—might be driving the crisis.

Searching for Answers

Scientists aren't just counting cases—they're hunting for causes. Teams are collecting soil and water samples, testing for pesticide residues and heavy metals. They're examining blood and urine for biomarkers that might reveal early warning signs before full disease develops.

The patterns already emerging are medically significant. "The study found that the levels of creatinine, urea and uric acid in the blood increased progressively with the severity of kidney disease," the report notes—clear evidence of declining filtration capacity as the condition advances.

Even more concerning: some residents showed abnormal urine albumin levels despite apparently normal kidney function, suggesting silent damage might be widespread.

The Human Landscape

Behind the statistics are people—mostly farmers and agricultural workers. About one-third of those screened are connected to farming, with 55.3% aged above 48. Lifestyle factors show tobacco use at 38.8% and alcohol consumption at 23.7%, though researchers caution against drawing simple conclusions.

The CSIR-Indian Institute of Chemical Technology in Hyderabad is assisting with environmental analysis, while the broader study—sanctioned with ₹6.2 crore over three years—continues its work under nephrologist T. Raviraj's mentorship and Professor G. Prasad's leadership.

Health Minister Satya Kumar expressed hope that final findings would pinpoint the underlying causes, potentially saving countless lives in this vulnerable region.
