1. What is the Insulin Dose Formula?

The insulin dose formula calculates the amount of insulin needed based on carbohydrate intake and current blood glucose levels. It combines both meal insulin (based on carbs) and correction insulin (based on current glucose levels).

2. How Does the Calculator Work?

The calculator uses the insulin dose formula:

\[ Dose = \frac{Carbs}{ICR} + \frac{BG - Target}{ISF} \]

Where:

\( Carbs \) — Carbohydrate intake (grams)
\( ICR \) — Insulin to Carb Ratio (grams/unit)
\( BG \) — Current Blood Glucose (mg/dL)
\( Target \) — Target Glucose Level (mg/dL)
\( ISF \) — Insulin Sensitivity Factor (mg/dL/unit)

Explanation: The first part calculates insulin needed for carbohydrates, while the second part calculates correction insulin to bring blood glucose to target level.

3. Importance of Insulin Dose Calculation

Details: Accurate insulin dosing is crucial for maintaining optimal blood glucose control, preventing hyperglycemia and hypoglycemia, and managing diabetes effectively.

4. Using the Calculator

Tips: Enter carbohydrate intake in grams, current blood glucose in mg/dL, target glucose in mg/dL, and your personal insulin sensitivity factors. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What if my blood glucose is below target?
A: The formula will calculate a negative correction dose, which means you may need to reduce your insulin or consume additional carbohydrates.

Q2: How do I determine my ICR and ISF values?
A: These are typically determined with your healthcare provider through testing and monitoring. They vary from person to person.

Q3: Should I round the insulin dose?
A: It's generally recommended to round to the nearest 0.5 or 1 unit based on your insulin delivery device capabilities and your healthcare provider's guidance.

Q4: Are there situations where this formula shouldn't be used?
A: This formula may need adjustment during illness, stress, exercise, or other special circumstances. Always consult with your healthcare provider.

Q5: How often should I recalculate my insulin needs?
A: Insulin needs can change over time. Regular monitoring and consultation with your healthcare team is recommended to adjust your ratios as needed.
