Insulin TDD and BMI Calculator app for iPhone and iPad

Insulin TDD and BMI Calculator calculates your adjusted BMI (Body Mass Index) and TDD (Total Daily Dose - combined basal and bolus dose). It is based on inputs such as an individuals weight (kg and lbs), height (cm and ft/in), age and gender. It calculates the BMI (Body Mass Index) based on the weight and height, then makes minor statistical adjustments to it for age and gender. It also calculates the TDD of insulin based on the adjusted BMI.

BMI (Body Mass Index) Calculation:
The standard BMI is calculated from the weight (in kg) and the height (in m).

BMI Adjustment for Gender:
Statistical research shows that females tend to have an average BMI that is 5 - 10% higher than men. Researchers believe this should not affect the total daily dose of insulin for females and their weight classification bracket should be adjusted to compensate for this minor difference.

BMI Adjustment for Age:
Research shows that individuals with age ranging from 2 to 19 years of age tend to have proportionately lower BMI than individuals 20 or older. Due to this statistical fact, researchers believe this should be taken into consideration when calculating the total daily dose of insulin for young individuals, and their percentile classification bracket should be adjusted to compensate for that difference.

TDD (Total Daily Dose) of Insulin Calculation and Adjustment for BMI:
The TDD calculation is based on an individual’s weight (in kg) multiplied by a factor related to the BMI. There are 4 factors/brackets used: Frail/Thin/Lean (smallest factor), Healthy, Overweight and Obese (largest factor).

Your TDD and BMI are common parameters, used to calculate your daily needs for bolus and basal rates.

Use this calculator only on advice from your physician. Your physician will provide you with the parameter values needed. This method for calculating these parameters is not suitable for everyone.
