1. What is Healthy BMI for Pregnant Women?

Healthy BMI for pregnant women refers to the body mass index calculated using pre-pregnancy weight and height. This measurement helps determine appropriate weight gain recommendations during pregnancy and assesses potential health risks for both mother and baby.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

\[ BMI = \frac{Pre\text{-}Pregnancy\ Weight}{Height^2} \]

Where:

\( Pre\text{-}Pregnancy\ Weight \) — Weight before pregnancy in kilograms (kg)
\( Height \) — Height in meters (m)
\( BMI \) — Body Mass Index in kg/m²

Explanation: The formula calculates body mass index by dividing pre-pregnancy weight by the square of height, providing a standardized measure of body composition.

3. Importance of Pre-Pregnancy BMI

Details: Pre-pregnancy BMI is crucial for determining appropriate weight gain during pregnancy, assessing nutritional needs, and identifying potential risks such as gestational diabetes, preeclampsia, or delivery complications.

4. Using the Calculator

Tips: Enter pre-pregnancy weight in kilograms and height in meters. Ensure accurate measurements for reliable results. All values must be valid (weight > 0, height > 0).
