Some dangers threaten those who are unaware of their blood glucose levels. Hypoglycemia (low blood glucose) occurs when a person living with diabetes unknowingly allows their blood glucose levels to drop under 70 mg/dl. This is also commonly referred to as an insulin reaction or insulin shock. A fast and simple way to treat hypoglycemia is to take a glucose tablet. These tablets contain fast-acting carbohydrates to raise blood glucose levels up to normal. IT is impeccable for diabetics to be prepared for all situations. That being said, they should carry around glucose tablets with their kits to ensure health safety. All orders over $99 receive FREE shipping.
