Insulin Calculator

The Insulin Calculator helps users determine the appropriate insulin dosage by calculating correction and meal doses based on blood sugar levels, carbohydrate intake, and activity level.

How to Use the Insulin Calculator

Step 1: Input Current Blood Sugar

Begin by entering your Current Blood Sugar (mg/dL) into the calculator. Ensure that the value is between 0 and 1000 mg/dL. This field is required, and you should enter the value based on your latest blood sugar test.

Step 2: Input Target Blood Sugar

Next, enter your Target Blood Sugar (mg/dL). The acceptable range is between 70 and 180 mg/dL. This is the level you aim to achieve after insulin administration, and it is also a required field.

Step 3: Enter Carbohydrates to Eat

Input the amount of Carbohydrates to Eat in grams. You must enter a value between 0 and 300 grams. Use this field to account for any carbohydrates you plan to consume in your meal. This is also a mandatory field.

Step 4: Specify Insulin Sensitivity Factor

Enter your Insulin Sensitivity Factor, which is expressed in mg/dL per unit. The value should be between 1 and 150. This factor is crucial as it indicates how much your blood sugar level decreases per unit of insulin.

Step 5: Define Carb to Insulin Ratio

Input your Carb to Insulin Ratio, in grams per unit. Acceptable values range from 1 to 50. This ratio helps determine the insulin dose needed for the carbohydrates you’re about to eat.

Step 6: Select Physical Activity Level

Choose your Physical Activity Level from the options provided. Your selection affects the total insulin dose. Options include:

  • No exercise planned (1.0)
  • Light exercise planned (0.9)
  • Moderate exercise planned (0.8)
  • Intense exercise planned (0.7)

Step 7: Review Result Fields

Based on your input, the calculator will provide the following results:

  • Correction Dose: This is calculated using the formula (bloodSugar – targetBloodSugar) / insulinSensitivity and is expressed in units. The result will be displayed with two decimal points.
  • Meal Dose: Determined by the formula carbIntake / carbRatio, also shown with two decimal points in units.
  • Total Insulin Dose: This value represents the overall insulin needed, calculated by the formula (correctionDose + mealDose) * activityLevel. It is presented as a total with two decimal points in units.

Review these results to understand the recommended insulin dosage tailored to your specific conditions.
