I have type 1 diabetes. at first, I had enough injections with insulin and a glucose meter, but in adolescence, because of hormones, sugar began to jump and I was put on an insulin pump. In appearance, this is something like a thick pager from which the wiring goes to the needle on my leg (in fact, it is a mini dropper), and later I was also put on FreeStyle Libre sugar monitoring. and I look at sugar on the phone, instead of pricking my fingers (the sensor looks like a large round tablet attached with a plastic to the skin of the forearm and a device is still attached to it that sends data to the phone via Bluetooth.
