At the end of November, I will have been wearing my Continuous Glucose Monitoring System (CGM) for one year. And I really don't know how I lived with type 1 diabetes without it? I know that I am unusual in that I get 21 to 30 days out of each sensor I wear. Or maybe my immune system is just completely useless altogether? So, I thought I would take a photo diary of the life of one of my CGM sensors and take you through what it looks like.
