The Right Weight for your Due Date

So you go to your OB/GYN (Obstetrician/Gynecologist) every check up, and the nurse checks your blood pressure. Then she does this little thing you  hate, she checks your weight. As if any pregnant woman needs a reminder of how much weight she’s gaining! You stand there like a middle school student waiting for your test results. Just like I did. Did you gain too much? Too little? Just enough? What is enough exactly anyway?

According to the  “Weight Gain During Pregnancy  guidelines” (PDF) published by  Institute of Medicine (IOM) 11.5-16 kg (25-35 lbs) is the recommended gestational weight gain (GWG) during the whole pregnancy. That is for a woman who had an average BMI (Body Mass Index) before pregnancy. Or in really simplified terms, if the expectant mother was average weight before pregnancy.

However, the amount of weight recommended for each woman is different depending on her BMI before pregnancy. To calculate your BMI  please enter your weight, height, age and sex before pregnancy in the tool below.

BMI less than 18.5
BMI between 18.5 and 24.9
BMI between 25 and 29.9
BMI above 30

What’s funny is that these weight ranges are “generous”. In the 1970’s according to an National Research Council (NRC report), the average ranged was 9.1–11.3 kg. I think I gained that much in the last trimester alone!

Why do these ranges matter?
