IMMEDIATE weight loss after birth

  1. Mar 15, 2014 #1

    In a similar vein to the weight of flying birds in a sealed van etc.

    Let's say a woman weighs exactly 10 stones 7 pounds on the morning she is due to give birth. She starts to dilate etc. and heads to hospital. She gives birth to a beautiful baby girl weighing in at exactly 7 pounds. Seconds after doing so the woman leaps off the bed and weighs herself again. Will she weight 10 stones or 10 stones 7 pounds - and why?

    Obviously if she now only weighs 10 stones I can work that one out!

    This is causing much heated debate in our household so your insight would be appreciated (unless I'm proved wrong)

    Hi Stephen

    She will weigh 10 stones for the same reason that a ten stone woman with a seven pound brick will weigh 10 stones after she drops the brick.

    I weighed 142 pounds when I gave birth, I weighed myself after I gave birth, still weighed 142 pounds. The doctor said it was due to extreme water retention and the added breast milk.

    The amount a woman that just gave birth can expect to lose.


    Don't be surprised if your actual weight loss is not as large.

    Well that's annoying!! I was rather hoping that like the birds in the van, the weight would remain constant!

    Thank you....
