Insulin pump therapy has evolved significantly, offering precise, automated, and flexible insulin delivery for patients with Type 1 and advanced Type 2 diabetes. Continuous subcutaneous insulin infusion (CSII) systems allow personalized basal and bolus dosing, reducing glycemic variability and minimizing hypoglycemia risk. Hybrid closed-loop and automated insulin delivery systems integrate continuous glucose monitoring (CGM) data with pump algorithms to dynamically adjust insulin in real time, mimicking physiological pancreatic function. Advances in user-friendly interfaces, mobile connectivity, and data analytics enhance patient adherence, monitoring, and remote management. By adopting these innovations, healthcare providers can optimize glycemic control, improve quality of life, and empower patients to manage their diabetes more effectively.
