When the Dexcom Follow app indicates that the server is unavailable, it signifies a disruption in the communication pathway between the continuous glucose monitoring (CGM) system and the remote monitoring application. This interruption prevents designated followers (parents, caregivers, or healthcare providers) from receiving real-time glucose data from the CGM user. For example, a parent might be unable to remotely monitor their child’s glucose levels during school hours if the server is unavailable.
The significance of a functional data transmission system lies in its ability to provide timely alerts about glucose excursions, potentially preventing hypoglycemia or hyperglycemia. This capability has proven beneficial in managing diabetes, particularly for vulnerable populations like children and individuals with impaired awareness of hypoglycemia. Historically, remote monitoring offered by such applications has improved glycemic control and reduced the burden of care on individuals managing diabetes.
