How To Calculate Insulin Dose For Diabetic Patient

Calculating insulin doses accurately is crucial for managing diabetes. This calculator helps you determine the right insulin dose based on your blood sugar levels, insulin sensitivity, and carb intake.

1. Enter your current blood sugar level in mg/dL.
2. Enter your insulin sensitivity in IU/U. This is the amount of insulin needed to lower your blood sugar by 1 unit.
3. Enter your carb ratio in g/CU. This is the amount of carbs that one unit of insulin covers.
4. Click ‘Calculate’ to see your recommended insulin dose.

The calculator uses the following formula to calculate the insulin dose:

Insulin Dose (IU) = (Blood Sugar Target – Blood Sugar Current) / Insulin Sensitivity + (Total Carbs / Carb Ratio)

Comparison of Insulin Types

Insulin Type	Onset of Action (minutes)	Peak Time (hours)	Duration of Action (hours)

• Always round your insulin dose to the nearest whole number.
• Consider using an insulin pump for more precise dosing and better control.
• Regularly review and update your insulin-to-carb ratio and correction factor to ensure accurate dosing.

What if my blood sugar is too low?

If your blood sugar is too low (hypoglycemia), you may need to treat it with glucose tablets or juice before calculating your insulin dose.
