Will 1/2 cc of insulin harm a non-diabetic?
Oh Yeah - if you dont happen to have a quart of OJ sitting in your lap when the plunger finishes you will have a dirt nap.
"Will 1/2 cc of insulin harm a non-diabetic?"
For type 2 diabetics, it may not do much because they lack the ability to correctly process the insulin. Whereas type 1 diabetics lack the ability to produce the insulin.
For everyone else, you need a certain amount of unprocessed sugar in your blood stream (glucose levels, 90-100 is normal). If you were to suddenly introduce a large amount of insulin into your blood stream, your blood-sugar level would drop faster than your body could keep up with since it wasn't the one providing the insulin. For some insulins, the person affected would start to feel a little tingly after 15 minutes. Then after about 30-60 minutes, it is possible they could pass out unless they got some sugar into their blood stream (i.e. cramming a couple twinkies). Though usually the fastest way to raise your blood sugar level is with something liquid (i.e. fruit juice).
