Baby weight

How much does your bump really weigh? Average figures for pregnancy weight gain revealed.
Its inevitable and necessary that you put on weight during pregnancy and it can be comforting to know that those extra pounds on the scales are a sign that your baby is growing healthily. But how much of your pregnancy weight gain is actually down to 'baby weight'?

Here are the 'average' figures......
  • Baby = 7.5 - 8.5lbs
  • Placenta = 1.5 - 2lbs
  • Amniotic fluid = 2lbs
  • Blood volume = 4lbs
  • Womb muscle = 2 -2.5lbs
  • Water = 4lbs
  • Breast tissue = 2lbs
  • Energy reserves (for labour) = 7lbs

Is it OK to lose a few punds in the first 5 weeks? I generally follow a health diet and exercise routine but I enjoy a drink and the odd takeaway, this means I maintain much of the time. However, since I have given up drinking and cut out the takeaways I am losing, poss around 5 lbs since the start. I guess this is good as I am over weight at 12st 11lbs anyway? I have plenty of reserves!

Im 26 weeks into my third pregnancy,, I suffer from an eating disorder and find the extra weight extremely difficult to contend with..

I swear, I had put on 3 stone at my last ill advised weigh- in! Im 25, and normally bang on 10st - size 10/12. Last time I weighed myself was at about 27 weeks- Im 37 weeks now, and DO NOT want to know how much more Ive put on! DONT WORRY ABOUT IT! Ive been excersizing, and eating healthily....I think its just natural to lay down fat when pregnant...and it doesnt last forever!

I haven't had that problem. Not yet, anyway! I am currently 28 weeks pregnant and have gained 1st and 10lbs already, which my GP recons is quite a lot for an 18 year old at 28 weeks. I feel so heavy and I get out of breath after just walking up the stairs, its really quite annoying!

I keep vomiting after eating. This has been going on for 2-3 days now. I phoned our "out of hour" service and the doctor said there is nothing much I can do to help stop it because it sounded like my baby is "too big" for my body and my body cant expand anymore, so baby is having to push upwards and the only way of relieving the pain is to have the baby. Has anyone else experianced this.? I am 34 weeks.
