The landscape of nephrology has shifted significantly in recent years. While diabetes and hypertension remain the leading causes of renal failure, a new wave of "modern" kidney ailments is emerging, driven by lifestyle changes, environmental factors, and climate shifts. Emerging Health Challenges One of the most prominent concerns today is Obesity-Related Glomerulopathy (ORG). As global obesity rates climb, researchers have identified that excess body mass forces the kidneys to work in a state of "hyperfiltration." This constant strain leads to scarring of the kidney’s filtering units, even in individuals without diabetes. Furthermore, Chronic Kidney Disease of unknown etiology (CKDu) is rising among agricultural workers in hot climates. Scientists believe this is a result of recurrent heat stress and chronic dehydration, highlighting how environmental labor conditions directly impact internal organ health. The Impact of Environment and Climate Recent studies suggest that Climate Change is a growing risk factor for kidney health. Rising global temperatures have been linked to an increased incidence of kidney stones and acute kidney injury (AKI) due to dehydration. Additionally, there is growing concern regarding PFAS (Per-and polyfluoroalkyl substances), often called "forever chemicals." These substances, found in various consumer products, can accumulate in the kidneys, potentially disrupting metabolic functions and leading to long-term cellular damage. The Future of Care Despite these challenges, we are entering an era of Precision Medicine. Artificial Intelligence (AI) is now being used to predict the decline of kidney function years before symptoms appear. Moreover, the emergence of SGLT2 inhibitors—originally developed for diabetes—has revolutionized kidney protection, offering a powerful tool to slow the progression of chronic disease. Understanding these modern threats is the first step toward proactive preservation of renal health. Prepared by Dr. Tuqa Hazem Abdullah Universit Al-Mustaqbal – The First University in Iraq
