Are hypoglycaemic episodes dangerous?

If corrective action is not taken, unconsciousness may result, but the body will take emergency action to raise glucose levels so that consciousness is regained. However, a person may be in a dangerous environment and need help, so it is important to take special measures when appropriate (e.g. driving) and to inform friends and workmates of the condition and what to do if help is needed. Death from a hypo is very rare.
