insulinpump

An insulin pump is a small, computerized device that delivers a continuous, basal rate of insulin to a person with diabetes. It also allows for bolus doses of insulin to be delivered manually by the user to cover meals or correct high blood glucose levels. The pump consists of a reservoir of insulin, a small battery-powered pump, and a thin plastic tube called an infusion set. The infusion set connects the reservoir to a cannula that is inserted under the skin, typically in the abdomen, thigh, or buttock.

Insulin pumps are programmed to deliver insulin in two ways: basal and bolus. The basal insulin provides a steady background supply of insulin throughout the day and night, mimicking the function of a healthy pancreas. The user or their healthcare provider can adjust the basal rate to match individual needs, such as changes in activity levels or time of day. Bolus insulin is delivered in larger doses to cover the carbohydrates consumed in meals or to correct high blood glucose readings. Users typically calculate their bolus doses based on carbohydrate counts and their current blood glucose level.

The use of an insulin pump can offer several advantages for people with diabetes, including improved blood glucose control, greater flexibility in meal timing and composition, and a reduced risk of severe hypoglycemia. However, it also requires a commitment to regular monitoring of blood glucose levels, careful management of the pump and infusion set, and ongoing education. Potential risks include site infections, blockages in the infusion set, or insulin delivery errors, which can lead to hyperglycemia or hypoglycemia. Regular consultation with a healthcare team is essential for safe and effective insulin pump therapy.
