CKD has many different triggers and is intertwined with a range of other illnesses, including cardiovascular disease and hypertension. An analysis published in 2025 showed that CKD is more common in regions with a high diabetes prevalence, such as Oceania and the Middle East. In other areas with high rates, the cause is attributed to genetic variants within regional populations, such as in West Africa and Central America. Variability across communities underscores the complex nature of this noninfectious disease.
