Where does my pregnancy weight come from?

Tracey: Gaining weight in your pregnancy is natural – it’s nothing to worry about. Lots of bits of your body change to prepare for pregnancy and to prepare for your growing baby. Your boobs grow, your bottom grows and your fluid in your body grows so there’s lots of things that can be attributed to getting bigger.

On average a baby at the end of pregnancy is seven to eight pounds, that’s three to three and a half kilos, that’s a size of a small bag of potatoes.

Your boobs or your breasts put on over an average of a kilo each - that’s a small bag of flour for each one.

The placenta on average is about as big as your hand. That weighs about 700grams which is nearly another kilo. That’s about the size of an average box of cereal.

So if you think about your uterus or your womb, that can weigh a kilo on its own but you put inside that a litre of fluid and that can weigh another kilo so that’s two bags of carrots.

Towards the end of you pregnancy, your circulating volume, that’s your blood and all the other fluids that whizz around your body increases. That can weigh as much as a couple of bags of sugar.

Towards the end of your pregnancy, you lay down lots of fat as well, thighs, bottom and around your waist. These are there for a particular reason – it’s to feed your baby. On average we put on about three kilos and that’s the size of a large chicken.

So next time you wonder around a supermarket collecting all your goodies for your Sunday roast, make your partner carry the bags and he’ll realise how much extra weight you’re carrying around.
