When starting insulin dosing, what is the recommended division of total daily insulin dosage?

The recommended division of total daily insulin dosage for individuals starting insulin therapy is typically 50% basal and 50% bolus. This approach strikes a balance between providing a background level of insulin to manage glucose levels throughout the day and offering additional doses around mealtimes to match the increased insulin requirements for carbohydrate intake.

Basal insulin works to maintain steady blood glucose levels during fasting periods or between meals, while bolus insulin is necessary to address the immediate rise in blood glucose that occurs after eating. By splitting the dosage evenly, it allows for effective management of blood glucose levels both at baseline and in response to meals. This division is particularly relevant in scenarios such as starting insulin for patients with Type 1 diabetes or those transitioning from oral medications to insulin therapy.

This balanced approach is crucial for achieving optimal glycemic control without risking significant hypoglycemia, making it a widely accepted starting point for insulin therapy.
