Advancements in diagnosis, management & treatment have significantly improved diabetes care, offering more precise and individualized approaches. Early diagnosis relies on fasting glucose, HbA1c levels, and continuous glucose monitoring, enabling timely intervention. Management strategies incorporate a combination of pharmacological treatments, lifestyle modifications, and emerging digital health technologies. While metformin remains a first-line therapy, newer agents such as GLP-1 receptor agonists and SGLT2 inhibitors provide cardiovascular and renal benefits beyond glycemic control. Insulin therapy continues to evolve, with ultra-long-acting formulations improving adherence. Personalized treatment plans integrating dietary counseling, physical activity, and behavioral support ensure optimal outcomes, while telemedicine and wearable devices enhance patient monitoring and engagement in diabetes self-care.
