The global epidemiology of diabetes highlights an alarming rise in prevalence across both developed and developing nations. Type 2 diabetes accounts for the majority of cases, driven by urbanization, sedentary lifestyles, and unhealthy dietary patterns. Low- and middle-income countries are experiencing the fastest growth, creating major public health challenges. Regional disparities reflect differences in healthcare access, socioeconomic status, and genetic susceptibility. Understanding these global patterns is crucial for implementing effective prevention programs, strengthening healthcare systems, and reducing disease burden. Coordinated international efforts, guided by evidence-based policies, can help curb the global diabetes epidemic and promote healthier communities worldwide.
