A review on glucose monitoring devices – Revolution in the world of diabetes

Diabetes is one of the most chronic diseases affecting millions across the globe, mainly in aging populations and sedentary lifestyles. Continuous glucose monitoring is essential for blood sugars and avoiding significant micro and macrovascular organ damage. The field of research has come up with major developments in glucose monitoring technologies over decades. However, the area of glucose biosensors still faces significant challenges. The traditional methods of glucose monitoring, such as hemoglobin A1c, seemed to provide little benefit in day-to-day glucose monitoring and the need for changing therapies. Researchers have come up with modern methods of non-invasive glucose monitoring, which are more efficient, robust and affordable for individuals of all ages. Continuous glucose monitoring( CGM) is one of the most reliable and clinically valuable methods that demonstrated the reducing risks of hypo/hyperglycemia, glycemic variability and improving the target blood glucose levels. In this article, we emphasize the advantages and limitations of CGM in diabetic and non-diabetic individuals, recent advancements in non-invasive technology and the significance of point-of-care glucose testing.
