Devices worn on the arm to continuously monitor blood sugar levels are not very good at detecting low blood glucose, or hypoglycemia, according to a recent study.
Hypoglycemia remains a major obstacle to the successful treatment of type 1 diabetes, especially in children. One of the greatest fears of patients and parents is the possibility of a severe hypoglycemic reaction. Low sugar can lead to disorientation or even loss of consciousness.
The purpose of the study, conducted by members of the Diabetes Research in Children Network (DirecNet) Study Group, was to assess the accuracy of the GlucoWatch G2 Biographer (GW2B) and the continuous glucose monitoring system (CGMS) during hypoglycemia in children and adolescents with type 1 diabetes.
