A new study released by the Centre for Maternal and Child Enquiries reveals that more than 5% of pregnant women in the UK are dangerously overweight. That equals to about 38,000 women whose body mass index is over 35.
The survey warns women about the severe consequences obesity can have on the health of an unborn child. Woman who are obese run twice the risk of having a stillborn child and also put themselves at risk of developing blood clots and high blood pressure.
