Continuous glucose monitoring system for congenital hyperinsulinemia.

Blood glucose monitoring is a way of testing the concentration of glucose in the blood. The most recent advance is the development of continuous glucose monitoring system (CGMS) which gives 24 hour trend of blood sugar levels thus helping both the patient and the physician in achieving better glycemic control. CGMS in pediatric population is generally used for those on insulin pumps and those who are having fluctuating blood glucose levels. This case highlights the use of CGMS for a child with congenital hyperinsulinemia. It helped in close monitoring of blood glucose levels thereby identifying recurrent hypoglycemia, leading to a better control of blood glucose levels.
