Is there a device that can constantly show my blood glucose levels? My grandmother needs one so she knows when she needs to take her medicine, but I don't know if I can buy one.

Yes, now there is a device that can be attached to the hand and it will transmit all the data to the phone. So you need to buy OmniPod and diabetic test strips for your grandmother to make it easier for her. In general, you can ask your doctor, he will tell you exactly what you need to buy. I also often buy different devices and medicines for my grandmother, because who else but us can take care of them?

It's really important to take care of your parents and grandparents because they once took care of you and helped you with everything.
