What is the function of an insulin pump?

An insulin pump is designed to provide a continuous supply of insulin subcutaneously, which closely mimics the body's normal pancreatic function. This continuous delivery helps maintain stable blood glucose levels throughout the day and night, unlike traditional methods that may rely on multiple daily injections. The insulin pump allows for precise adjustments in insulin delivery to meet the patient's varying needs, such as increased insulin during meals and adjustments for activity level.

This continuous subcutaneous infusion helps prevent fluctuations in blood sugar levels that can occur with other methods of insulin administration, thereby improving overall glycemic control and reducing the risk of complications associated with diabetes. The ability to continuously deliver insulin helps individuals achieve better management of their condition by better simulating the body's natural release of insulin as glucose levels rise or fall.
