Yes.
You can buy a bracelet from several different companies, and have anything you like written on it.
You can also get cards to carry in your wallet or purse.
I have a bracelet that lists bee sting allergy and gluten intolerance, as well as T2 and RH. In my situation, the allergy and intolerance are probably more important than the T2 - but then, I am not on insulin.
I got my bracelet from Medicalert, and pay a fee annually for them to keep additional details available (such as blood type). First responders and healthcare professionals can contact Medicalert 24/7 and access further details, if I have recorded those details.
Other bracelets can be as simple as a silicon band, or very decorative, but my suggestion is that you don't choose anything too ornamental. It needs to be quickly and easily identified by (for example) a paramedic in an emergency.
