CSII

CSII, or Continuous Subcutaneous Insulin Infusion, is a method of delivering insulin to manage diabetes. It utilizes an insulin pump, a small device worn externally, to provide a continuous, small dose of rapid-acting insulin throughout the day. This basal insulin mimics the body's natural insulin production, providing a steady supply to cover background glucose needs. In addition to the basal rate, CSII allows for bolus doses of insulin to be delivered manually by the user to cover meals and correct high blood glucose levels.

The benefits of CSII often include improved glycemic control, with potential for lower A1c levels and reduced instances of hypoglycemia. The flexibility of adjusting basal rates and bolus sizes offers more personalized diabetes management compared to multiple daily injections. However, CSII requires a significant commitment from the user, including regular monitoring of blood glucose, pump management, and understanding insulin-to-carbohydrate ratios and correction factors. Potential drawbacks include the cost of the pump and supplies, the risk of pump malfunction or infusion site issues, and the psychological adjustment to wearing a device. CSII is typically prescribed for individuals with type 1 diabetes or type 2 diabetes who have difficulty achieving their glycemic targets with other insulin delivery methods.
