CGM systems are revolutionizing diabetes management by providing real-time glucose readings every few minutes. Unlike traditional fingerstick testing, CGM devices alert patients and healthcare providers to trends and dangerous glucose levels, supporting tight glycemic control. Nurses increasingly educate patients on CGM use, interpret trends for insulin adjustments, and integrate data into telehealth visits. With rising rates of Type 2 diabetes and the shift toward patient-centered care, CGMs empower individuals and reduce hospital admissions for hypo- or hyperglycemia.
