Pregnancy Weight Gain Formulas
BMI Calculation Formula
BMI = (Weight in pounds / (Height in inches)²) × 703
Or
BMI = Weight in kilograms / (Height in meters)²
Total Pregnancy Weight Gain Recommendations
Based on pre-pregnancy BMI (Institute of Medicine guidelines):
- Underweight (BMI < 18.5): 28-40 lbs (12.5-18 kg)
- Normal weight (BMI 18.5-24.9): 25-35 lbs (11.5-16 kg)
- Overweight (BMI 25-29.9): 15-25 lbs (7-11.5 kg)
- Obese (BMI ≥ 30): 11-20 lbs (5-9 kg)
Trimester Weight Gain Patterns
First Trimester ( Weeks 1-13): 1-5 lbs total (0.5-2 kg)
Second Trimester (Weeks 14-27): Approximately 1 lb per week (0.5 kg)
Third Trimester (Weeks 28-40): Approximately 1 lb per week (0.5 kg)
Note: These are general patterns; individual experiences vary
Example Calculation
Let's calculate recommended weight gain for a woman who is 5'4" (64 inches) with a pre-pregnancy weight of 140 lbs at 20 weeks pregnant:
- BMI = (140 / (64)²) × 703 = (140 / 4096) × 703 = 0.03418 × 703 = 24.02
- BMI Category: Normal weight (18.5-24.9)
- Total recommended gain: 25-35 lbs
- By 20 weeks: Approximately 10 lbs (1-5 lbs in first trimester + 0.5 lb/week in second trimester)
- Recommended range at 20 weeks: 8-12 lbs
If her current weight is 155 lbs, she has gained 15 lbs, which is slightly above the recommended range at this stage.
