I don't wear a medical alert bracelet for diabetes, nor do I carry a card. I am type 2, diet only, no meds for anything at all. However, I did have an alert bracelet when I was on chemo, and the hospital gave me a red medical alert card to be carried with me at all times. This was also an aid to bye-passing A&E straight to the Medical Assessment Unit should I have had an accident/become ill. I burnt them in celebration after my treatment was finished.
