Glucose Monitoring

Physicians are able to help their patients taking insulin manage their diabetes by reviewing home blood sugar readings. With diabetes on the rise and the increased risk of cardiovascular disease and infections as a result of this chronic illness, patients are encouraged to maintain well-controlled blood sugar readings and achieve desired hemoglobin A1C results.

Blood Glucose Meters (BGM) have been used for years to monitor blood sugar levels. The first home meter used by patients was developed in the 1980’s. This meter requires a specimen of blood to be exposed to an enzyme on a test strip. The enzyme oxidizes the blood. An electrode reads the current of the oxidized blood which equates to the amount of oxidized glucose. This process can be quite cumbersome and time-consuming especially for children and busy working adults. Moreover, the meter only provides a blood sugar reading for a single moment in time.

Continuous Glucose Monitors (CGM) on the other hand offers nearly 24/7 blood sugar monitoring. CGM’s have enabled patients to track their blood sugar levels easily, continuously, and accurately in addition to sharing this information with their physicians remotely. Patients no longer have to prick their finger with a needle and insert their blood sample on a test strip that is placed into a blood glucose meter.

Evolution of Procedure

Glucose Monitoring

Diabetics can now simply wear a device on their upper arm, receive real-time information on blood sugar fluctuations, respond to abnormal blood sugar readings, and share this data with their physicians.

Evolution of Diagnosis


Diabetes is a condition that occurs when blood sugar levels are too high as a result of the body’s inability to properly respond to sugar released from food. Insulin is a hormone produced by the pancreas that regulates blood sugar levels. In Type II diabetes the pancreas produces little to no insulin and in Type II diabetes the body is resistant to the insulin produced.

Therefore, Type I diabetics must take insulin to control their blood sugar and certain Type II diabetics must take insulin as well when oral medication proves ineffective. The use of insulin requires frequent monitoring of blood sugar levels to ensure the right dose of insulin is being administered as well as to monitor and address blood sugar levels that are too high or low.
