1. What is Pregnancy Weight Gain Calculator?

The Pregnancy Weight Gain Calculator based on NSW Health guidelines helps expectant mothers determine appropriate weight gain during pregnancy based on their pre-pregnancy BMI. Proper weight management is crucial for maternal and fetal health.

2. How Does the Calculator Work?

The calculator uses NSW Health pregnancy weight gain guidelines:

Recommended Gain (kg) based on BMI (kg/m²):

  • Underweight (BMI < 18.5): 12.5-18 kg
  • Normal weight (BMI 18.5-24.9): 11.5-16 kg
  • Overweight (BMI 25-29.9): 7-11.5 kg

Explanation: These guidelines are evidence-based and designed to optimize outcomes for both mother and baby while minimizing pregnancy complications.
