Pregnancy Weight Gain


IMPORTANT: This calculator is for adult pregnant women only. To determine BMI for others, please use our Standard BMI Assessment Tool.

For a healthy baby to develop, it is important for mom to gain enough weight during pregnancy. Although some moms fail to gain enough, it is a fairly rare problem in the U.S. Gaining too much weight however is very common and can lead to an overweight child. Moms who gain too much weight are more likely to give birth to children who may be fatter than normal at birth and more likely to become obese by the age of 4. So gaining enough weight, but not too much weight, is a very important goal for preventing childhood obesity. The recommended weight gain during pregnancy depends on your personal body mass index (known as BMI) before your pregnancy.

The question you may be asking is: What is the recommended weight gain for me? The answer depends on your pre-pregnancy BMI, which is determined by your height and weight just before you became pregnant.
