What is the Pregnancy Weight Gain Calculator & How does it work?
Pregnancy weight gain is crucial for maternal and fetal health. The Pregnancy Weight Gain Calculator uses your pre-pregnancy Body Mass Index (BMI) to determine a healthy range of weight gain throughout pregnancy.According to the Institute of Medicine, women with a normal BMI (18.5-24.9) should aim for a total weight gain of 25-35 pounds over their pregnancy. Underweight women (BMI < 18.5) may need more weight gain, while overweight or obese women (BMI ≥ 25) should gain less.
G = \begin{cases} 25-35\text{ lbs}, & \text{if BMI } 18.5-24.9 \\ 28-40\text{ lbs}, & \text{if BMI } < 18.5 \\ 15-25\text{ lbs}, & \text{if BMI } 25-29.9 \\ 11-20\text{ lbs}, & \text{if BMI } \geq 30 \end{cases}
G = Recommended total weight gain in pounds
