An insulin pump is a computerized device mainly used by people suffering from diabetes. It mimics the functioning of the pancreas, which is an organ that breaks down sugar, fats, and starches into simpler substances. An insulin pump works by delivering small doses of short acting insulin continuously (basal rate). The device is also used to deliver variable amounts of insulin when a meal is consumed (known as bolus insulin). While the basal insulin rates in the pump are set up by your doctor, you can program the amount of bolus insulin directly on the pump. Most pumps also come with built-in bolus calculators to help you figure out how much insulin you need at mealtime based on your glucose levels and the amount of carbohydrates you are eating.
