Childbirth and mother's obesity

Liverpool scientists have uncovered the reason why overweight women have more Caesarean sections; they are at significant risk of their uterus contracting poorly in childbirth.

In a study of 4,000 pregnant women, researchers found that almost 1 in 5 overweight women had to undergo an emergency Caesarean Section birth because the muscles in their uterus failed. The research suggests obesity impairs the ability of the uterus to contract sufficiently in order to dilate the cervix and deliver the baby.

The team from the University of Liverpool's Physiology department found that obese women were 3.5 times more likely to require a Caesarean for slow labour than normal weight women.

Obese women who gave birth vaginally were also found to encounter other problems in child birth
