There are two sorts of diabetic problems: Insulin Shock and Diabetic Coma. The best and least demanding way to decide whether the person has diabetes is to verify whether they have an arm bracelet which shows a medic alert. This will guide you in figuring out what first aid you may need to do.
In the case of insulin shock, the diabetic person needs sugar because they have not ingested enough nourishment to keep their sugar on par or they have taken excessively insulin. A portion of the indications of insulin shock is the person having a solid and rapid heartbeat and having a problem with relaxing. Insulin shock grows rapidly and requires medicinal consideration immediately. So better call for some help!
In a diabetic coma, the person needs insulin because their body does not deliver enough insulin to change the sugar they have ingested to energy. A portion of the indications of a diabetic coma-like state is a powerless and rapid heartbeat and hard breathing. The impacts of diabetic coma take a few hours or days to create and are in this manner not as problematic as an insulin shock.
Since it can be a trouble to figure out what sort of diabetic crisis you are experienced in dealing with, the first aid for both will be the same. Give sugar immediately. Either get some sweet candy, table sugar, or squeezed orange. This will help the person suffering from an insulin shock immediately, but may not work for the case of diabetic coma. Since diabetic coma state takes hours or days, they have adequate time to get to a clinic for treatment.
Let yourself be aware of these and you will probably save a life someday.
