People who suffer from diabetes need to control their blood sugar levels by balancing the amount of sugar in their diet with insulin injections. Therefore if they have missed a meal or taken too much exercise, the concentration of sugar in their blood will fall, and unconsciousness can follow. Someone who is being treated for diabetes may carry a card or identity bracelet with them indicating that they have diabetes, they will probably also be carrying some form of medication, such as hypodermic needles or insulin bottles.

Action Plan

The aim is to restore the sugar/insulin balance as soon as possible. If the casualty is conscious and capable of swallowing, immediately give them sugar lumps, a sugary drink, chocolate or other sweet food in order to restore the level of sugar in the blood. If the casualty is unconscious do not give them anything by mouth, if they are breathing normally put them in the recovery position and carry out general treatment for unconsciousness.

Call for an ambulance immediately.
