About the pregnancy weight gain calculator

This calculator will allow you to determine a healthy weight gain schedule for your entire pregnancy, based on your individual characteristics including weight before pregnancy, your height and type of pregnancy.

Pregnancy guidelines for weight gain

Pregnancy leads to significant changes to women’s bodies and their daily routines. One of these is the body weight gain to ensure enough nutrients for the development of the fetus and to store enough nutrients in preparation for breastfeeding. While weight gain during pregnancy is normal and necessary, studies have shown that certain ranges of weight gain given a specific body mass index (BMI) result in more positive outcomes for both fetus and mother.

Generally, it is recommended that pregnant women gain only 1-4 pounds during the first 3 months of pregnancy, and 1 pound per week during the remainder of the pregnancy.  The tables below will help you understand the results of the calculator.
