What is the role of insulin in the treatment of diabetes?

Insulin plays a crucial role in managing diabetes primarily by acting to lower blood glucose levels. In individuals with diabetes, particularly those with type 1 diabetes, the body is unable to produce sufficient insulin, which is vital for transporting glucose from the bloodstream into the cells for energy. By facilitating this process, insulin helps to maintain normal blood glucose levels and prevents hyperglycemia, which can lead to serious complications over time.

When insulin is administered as part of a treatment plan, it assists in regulating glucose levels effectively. This is especially important in diabetes management to reduce the risk of both short-term and long-term complications associated with high blood sugar. Therefore, the role of insulin in this context is clearly focused on lowering blood glucose levels, making it a key component of diabetes treatment.
