Pregnancy Weight Gain Calculator
Ultimate Guide to Healthy Pregnancy Weight Gain
By CalculatorUSAApp Team |
Introduction
During pregnancy, gaining weight within recommended ranges is vital for maternal and fetal health. The Pregnancy Weight Gain Calculator above uses current US guidelines from the ACOG and CDC to estimate healthy gain based on pre-pregnancy BMI and gestational week. In this guide, learn why weight gain matters, how to use this tool effectively, and practical tips to stay on track.
How to Use the Calculator
- Enter Pre-pregnancy BMI: Calculate BMI from your height and pre-pregnancy weight.
- Select Current Week: Choose your current gestation week (1–40).
- Review Recommendation: Get an instant recommended gain to date and total by week 40.
This tool adapts recommendations dynamically, helping you set achievable targets each week.
US Guidelines Overview
The Institute of Medicine (IOM) specifies total pregnancy weight gain by BMI category:
- Underweight (BMI<18.5): 28–40 lbs
- Normal (BMI 18.5–24.9): 25–35 lbs
- Overweight (BMI 25–29.9): 15–25 lbs
- Obese (BMI≥30): 11–20 lbs
These ranges support fetal growth while minimizing risks like gestational diabetes or complications at birth.
Nutrition & Lifestyle Tips
Balanced diet and moderate exercise are key. Focus on:
- Leafy greens, lean proteins, whole grains, and healthy fats.
- Small, frequent meals to manage nausea and blood sugar.
- Low-impact activities: walking, prenatal yoga, or swimming.
- Staying hydrated: aim for 8–10 glasses of water daily.
Consult your healthcare provider before starting new supplements or workout plans.
