1. What is the Correction Factor?

The Correction Factor (also called insulin sensitivity factor) estimates how much 1 unit of rapid-acting insulin will lower blood glucose. It's calculated based on your total daily insulin dose (TDD).

2. How Does the Calculator Work?

The calculator uses the standard formula:

Where:

• 1700 — Constant derived from clinical studies
• TDD — Sum of all insulin (basal + bolus) taken in 24 hours

Explanation: The formula shows an inverse relationship between total insulin needs and insulin sensitivity - those requiring more insulin are generally less sensitive to it.

3. Importance of Correction Factor

Details: Knowing your correction factor helps calculate insulin doses needed to correct high blood glucose levels while avoiding hypoglycemia.

4. Using the Calculator

Tips: Enter your total daily insulin dose in units (basal + bolus insulin). The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is 1700 used in the formula?
A: 1700 is an empirically derived constant that represents the average glucose lowering effect of insulin in adults.

Q2: Does this work for children?
A: For children, some clinicians use 1500 instead of 1700 as they tend to be more insulin sensitive.

Q3: How often should I recalculate my correction factor?
A: Recalculate whenever your total daily insulin dose changes significantly (by 10% or more).

Q4: What if my actual correction needs are different?
A: This provides an estimate - individual factors may require adjustment. Always confirm with your healthcare provider.

Q5: Can I use this for pump therapy?
A: Yes, the correction factor is used similarly in pump therapy and multiple daily injection regimens.
