1. What is BMI in Pregnancy?

Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to pregnant women. It helps determine appropriate weight gain during pregnancy and assess potential risks.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula adjusted for pregnancy:

Where:

• \( weight \) — Current weight in kilograms
• \( height \) — Height in meters

Pregnancy Adjustment: The calculator provides trimester-specific weight gain recommendations based on pre-pregnancy BMI categories.

3. Importance of BMI During Pregnancy

Details: Maintaining a healthy BMI during pregnancy reduces risks of complications like gestational diabetes, preeclampsia, and cesarean delivery. It also supports fetal development.

4. Using the Calculator

Tips: Enter current weight in kg, height in meters, and select your pregnancy trimester. For most accurate results, measure weight in the morning before eating.
