What is the difference between silicon-based dynamic CGM and traditional finger blood glucose meter?

After sugar friends get sick, they need to be highly sensitive to their blood sugar in real time, both high and low, so as to cope with high blood sugar in time. For sugar friends who have just fallen ill, I suggest using silicon-based dynamic CGM to measure blood sugar. Because the difference between this instrument and the traditional blood glucose meter is that it can detect blood glucose every five minutes, which can effectively avoid the situation of being too high or too low.
