Advancements in artificial pancreas and closed-loop systems are revolutionizing diabetes care by automating glucose regulation. These systems integrate continuous glucose monitors with insulin pumps, enabling real-time adjustments based on glucose fluctuations. Hybrid closed-loop models have significantly improved glycemic control, reducing the burden of frequent insulin adjustments. Innovations in dual-hormone systems, incorporating glucagon alongside insulin, aim to further enhance stability and minimize hypoglycemia risks. While current technology continues to evolve, challenges such as sensor accuracy, accessibility, and cost remain. With ongoing development, fully automated, next-generation artificial pancreas systems are expected to provide more precise, user-friendly solutions for diabetes management.
