Continuous Glucose Monitoring Systems (CGM)
When being diabetic, you have to constantly check and keep track of your BG levels, especially before eating and whenever there are any high or low levels involved. This is where the continuous glucose monitoring systems come into play. They check the user's blood sugars every 5 minutes, warning him/her of any possible lows or highs that could happen. CGMs work through a tiny electrode called a glucose sensor that is inserted under the user's skin to measure glucose levels in tissue fluids. The information is continuously sent via wireless radio frequency to the monitor and display device. Some even have the ability of predicting and alerting the user of any possible-happening low or high BG levels before they occur. This gives the user the ability to either eat if low of the sugar, or take some fast- acting insulin in case of a high blood glucose.
