Monitoring of blood sugar
If the student is using a glucometer to check blood sugar, the recommended frequency of blood sugar monitoring is four or more time per day. It is usually before all meals and before bedtime. This means that most students will require a blood sugar at least once (before lunch) during school hours. More frequent blood sugar monitoring , 2 hours after meal or before exercise, may be required in some students and will be indicated in the individual diabetes management plan. It is also recommended that blood sugar be checked if the student experiences symptoms of low blood sugar such as shakiness, or high blood sugar such as frequent urination.
Continuous Glucose Monitoring (CGM)
This is the most advance technology in blood sugar monitoring. The device reads blood sugar level in the tissue fluid between one to five minutes depending on the brand. There is a lag time between tissue fluid and real blood sugar because the sugar must pass through blood vessels to reach the tissue. But this lag time is compensated by the constant reading of the sugar level.
Most current models of CGM do not require a calibration with blood sugar. However, real blood sugar level should be obtained if the device reads extremely high or extremely low sugar level.
FDA also approves the use of CGM in making the treatment decision in patients with diabetes mellitus. Please refer to the student's diabetes medical management plan (DMMP) for specific instructions regarding sugar monitoring.
