Diabetic monitors are used for individuals with diabetes to monitor their blood glucose levels. Rather than sticking their fingers numerous times throughout the day, this new class of monitors is a wireless system that continuously monitors blood glucose levels. They are recommended for diabetics who experience frequent bouts of hypoglycemia, particularly while asleep. The monitor allows the wearer to prevent spikes and drops in blood sugar levels before they become dangerous.
The continual monitoring prevents the sudden drop in blood sugar levels that are often missed in between finger testings. According to a study published in Diabetes Care, diabetic monitors reduced hypoglycemic episodes in the individuals studied. The American Diabetes Association also showed that diabetic monitors can reduce the discomfort experienced by diabetics.
The device fits in a person's pocket and is connected to a sensor that is inserted beneath the skin. The sensor, which is replaced every few days, checks blood sugar levels every 5 minutes, 24 hours a day. The measurement is then wirelessly sent back to the pocket meter where the reading is evaluated. If blood sugar levels drop or exceed a preset level, an alarm goes off and the wearer makes the appropriate adjustments to stabilize blood sugar levels. The alarm will continue to go off until levels have stabilized.
Two finger sticks are needed throughout the day in order to ensure the accuracy of the monitor. In addition, the monitor displays a graph of the pattern in blood sugar levels, making it easier to predict where levels might be going and to make the necessary adjustments.
What to Look for
Currently, there are two diabetic monitors that have been approved by the Federal Food and Drug Administration (FDA): STS Continuous Glucose Monitoring System created DexCom and the MiniMed Paradigm created by Medtronics. The MiniMed also includes an insulin pump, which is inserted in the wearer's thigh.
The meter costs about $450 and extra supplies, such as additional sensors, add another $250 each month.
Common Pitfalls
The diabetic monitor is not meant to take the place of finger testings. It is instead meant to provide the wearer with a constant monitoring system of blood sugar levels. If the diabetic monitor's alarm goes off signaling a spike or drop in blood sugar levels, a finger-stick blood sample must follow. This will not just ensure an accurate reading but it will also help you decide whether or not food or a dose of insulin will stabilize levels.
Also, the diabetic monitor requires that the individual is properly and thoroughly educated on the operation of this device. The diabetic must also have a firm knowledge of the disease in order to make the proper decisions on what kind of action is necessary in order to stabilize their blood sugar levels.
