The basal-bolus insulin regimen is a commonly used approach for managing diabetes. It involves the use of two different types of insulin: basal insulin and bolus insulin. This regimen aims to mimic the natural insulin secretion pattern of a healthy pancreas.

Basal insulin is a long-acting insulin that provides a steady, background level of insulin throughout the day and night, even between meals. It helps control blood sugar levels between meals and during periods of fasting, such as overnight. Basal insulin covers the body's basal, or baseline, insulin needs. On the other hand, bolus insulin, also known as mealtime or rapid-acting insulin, is taken before meals to control the blood sugar rise that occurs after eating. It acts quickly to lower blood glucose levels and covers the increase in blood sugar caused by food intake.

In addition to mealtime bolus insulin, additional bolus doses may be needed to correct high blood sugar levels throughout the day. This correction bolus is calculated based on an individual's insulin sensitivity factor, which represents how much one unit of insulin is expected to lower blood sugar levels. The basal-bolus insulin regimen provides more flexibility and precision in matching insulin delivery to an individual's needs. It allows for better control over blood sugar levels throughout the day and helps maintain a more stable and normal glucose profile. Let's ;isten in to learn more.
