Pregnancy Weight Gain Calculator

This Pregnancy Weight Gain Calculator works in three simple steps:

1. You enter your stats: Input your height, weight before pregnancy, current weight, and how many weeks pregnant you are.
2. It calculates your BMI category: Using your pre-pregnancy details, it determines if you are Underweight, Normal Weight, Overweight, or Obese. Each category has a different total weight gain goal (e.g., 25-35 lbs for a normal BMI).
3. It gives you a personalized snapshot: The calculator compares your current weight gain to the recommended range for your specific week of pregnancy. It shows a progress chart, tells you if you're on track, and provides a trimester-by-trimester guide for healthy gain.

Your Guide to Healthy Pregnancy Weight Gain

Gaining weight during pregnancy isn't just normal—it's essential for your baby's healthy development. But how much is right for you? The answer depends on your starting point, which is why a Pregnancy Weight Gain Calculator is such a helpful tool for setting personalized, healthy goals.

According to the Institute of Medicine, your ideal weight gain is based on your pre-pregnancy Body Mass Index (BMI):

· Underweight (BMI < 18.5): Gain 28-40 lbs
· Normal weight (BMI 18.5-24.9): Gain 25-35 lbs
· Overweight (BMI 25-29.9): Gain 15-25 lbs
· Obese (BMI ≥ 30): Gain 11-20 lbs

This weight isn't just baby—it supports the placenta, amniotic fluid, increased blood volume, breast tissue, and vital nutrient stores.

Tracking your progress helps ensure you’re on target for a healthy pregnancy and can reduce risks of complications like gestational diabetes or preterm birth. Remember, the goal is steady, gradual growth to nourish both you and your little one.
