Diabetic coma is an emergency. You cannot be prepared in advance. If you have the feeling of an extreme high or low blood sugar you should call your local emergency number. You need to ensure help before you pass out.

If there is a person with you instruct him/her about it. If this person is familiar with diabetes care he/she should:

1. Test your blood sugar.
2. If the blood sugar level is lower than 70 mg/dL (3.9 mmol/L), administer an injection of glucagon. If glucagon isn’t available, rub glucose gel, honey or non-sugar-free syrup on the inside of the unconscious person’s cheek. No insulin should be given!
3. If the blood sugar level is above 70 mg/dL, wait for medical help to arrive. Don’t give sugar to someone whose blood sugar isn’t low.

Let the emergency care team know about the diabetes and what steps have been taken, if any.
