India tops global diabetes list with 212 million cases in 2022: Lancet Study

India has the highest global prevalence of diabetes, with 212 million adults diagnosed in 2022, surpassing China and the United States. A new study published in The Lancet reveals that the global diabetic population has quadrupled since 1990, now exceeding 800 million. The surge in India is attributed in part to broader diagnostic criteria, including fasting glucose and HbA1c levels.
