Hypoglycemia (or a low) is when blood glucose levels fall below 70 mg/dl. Signs include hunger, nervousness, shakiness, perspiration, dizziness or light-headedness, sleepiness, and confusion. Hypoglycemia is treated by consuming a carbohydrate-rich food such as a glucose tablet or juice. It may also be treated with an injection of glucagon, if the person is unconscious or unable to swallow. If left untreated, hypoglycemia may lead to unconsciousness. Also called an insulin reaction.
