Many people with diabetes are tired of pricking their fingers to know their blood glucose levels. However, it is necessary to prevent complications. They will be happy to learn that there is now a way to monitor blood glucose levels painlessly – and it is called Flash Glucose Monitoring.
How does it work?
Flash Glucose Monitor is composed of two parts: (1) a small sensor that sticks to the skin; and (2) a reading device. The sensor must be placed at the back of a person’s upper arm. To get a reading, the reader must be swiped over the sensor. For every scan of the reading device, one can view his blood sugar levels for the past eight hours. The sensor must not be removed once placed to come up with the blood glucose level and trend. The sensor can be worn for up to 14 days before replacement.
How can it measure the blood glucose level if it doesn’t acquire a blood sample? The sensor does not actually need blood as it uses the interstitial fluid. Interstitial fluid surrounds a person’s body cells. The level of glucose in the interstitial fluid lags by five minutes as compared to glucose levels in the blood.
Cons of Using Flash Glucose Monitor
Unlike continuous glucose monitoring, an alarm cannot be set when blood glucose reaches a low or high level since a reading can only be taken when the device is swiped over the sensor. Also, because of the five-minute lag, one would have to prick his finger when his blood sugar level is shifting rapidly, such as after having a meal or after working out.
Pros of Using a Flash Glucose Monitor
The main advantage (and also the most attractive one) is that there is no need for finger pricks. Since a person can check the trend of blood glucose levels for the past eight hours, he can manage his diabetes more efficiently. If there is a rise in the trend, the person can work towards lowering them so as not to go higher. One can even see his glucose levels for the past night while he was asleep.
Flash Glucose Monitoring is great for people with any diabetes, and can also be used on children, from four years of age and above. There is no need to calibrate the device which is good news for people who like to travel.
