How much weight should a woman gain during pregnancy?
It is considered normal to gain 10 to 12kg (22 to 26lb).
For practical reasons the pregnancy is divided into three periods:
- the first period runs from week 0 to 12 where it is normal to gain 1 to 2kg (2 to 4lb).
- the second period runs from weeks 12 to 28 in which it is normal to gain 300 to 400g (10 to 14oz) a week.
It is not necessary to be obsessive about your weight during pregnancy. Many obstetricians have stopped weighing women other than at their first visit because the information is of little use in detecting problems with the mother or her baby.
- the third period runs from weeks 28 to 40 and it is normal to gain 1 to 3kg (2 to 6lb) a month.
However, excess weight gain is probably best avoided since most women will want to return to the same dress size within a few months of delivery.
