Gaining Weight

Gaining Weight

Doctors recommend that a woman of average weight, experiencing an average pregnancy, ought to gain around 10-15kg (20-30lb) in the total 40 weeks gestation.

This allows about 3-4kg (6-8lb) for the baby and about 7-12kg (14-24lb) for the baby-support system (placenta, amniotic fluid, increased blood, fluid, fat, and breast tissue).

It is usual to gain very little, if anything, during the first trimester, around 0.5-1kg (1-2lb) each week between months four and eight, then very little, or none at all, in the last month. A steady gain like this means that your body can adapt more easily to your increasing size, and your baby is provided with a continuous flow of nourishment.

Of course each pregnancy is different and you may find you do not fit within these guidelines. This is quite normal. Talk to your doctor or midwife if you have any concerns about your weight gain.
