Say: in-suh-lin pump
A person needs the hormone insulin so the body can function properly. If a person's body doesn't make enough insulin, one way to get it is through an insulin pump. Some people with diabetes use this. The pump is a small battery-operated device that can be worn on a belt or put in a pocket. It's connected to a narrow plastic tube that's inserted just under the skin and taped in place. The pump can be programmed to deliver insulin throughout the day and to release extra insulin when needed, such as after eating.
