Hi PrincessLeia,
No question is a silly question, thats what the forum is for.
As you are diet controlled then the chances of having a need for medical staff to need to intervene due to your diabetes is minimal. Diet only controlled diabetics are unlikely to have a full/true hypo.
In the case of an emergency where you are unable to communicate to medical staff, a quick blood glucose check is routinely carried out.
However, in early days of diagnosis a medic alert bracelet can give peace of mind and act as a reminder to watch your diet or take exercise or check bloods.
A brightly printed card in your handbag or purse would be useful.
For home use, you can get a small pot you keep in your fridge that emergency personnel check, you list all your medical needs - you can get them from your local Lions organisation (they often give them out during local community events).
