If you or your partner are planning on giving birth in Korea (where just about one in two babies are deliverd by C-sections) consider this:
Caesarean sections linked to higher risk of hysterectomies
| Quote: |
Women who have had a caesarean section run a significantly increased risk of needing a hysterectomy following the birth of their next child, a major study from Oxford University has found.
The study is one of the few to have looked at the long-term consequences of caesarean sections, which have increased in popularity in the UK and around the world. It shows that the risk of a hysterectomy next time round - which will put an end to their childbearing - is raised by 350% in those women who have a caesarean.
Dr Marian Knight, senior clinical research fellow and honorary consultant in public health at the national perinatal epidemiology unit at Oxford said it was rare for a woman to have a hysterectomy following childbirth, "but there is no doubt that there is a big increase in risk with previous delivery by caesarean section". For most women giving birth normally for the first time, a hysterectomy is rare - only one in 30,000 will need surgery to remove their womb because of bleeding complications.
But the risk of having to undergo surgery to remove the womb rises massively in the subsequent pregnancy for those who had a caesarean. One in 1,300 women who have had one previous caesarean will have a hysterectomy. If she has had two or more previous caesareans, the risk rises to one in 220.
Researchers estimate that more than 80 women a year have been forced to have a hysterectomy as a result of having a caesarian. But with the popularity of the procedure on the rise this figure is likely to increase. The study of 775,000 women who gave birth between February 2005 and February 2006 in the UK also found that women with twin pregnancies, older mothers and those who already had three or more children were also at higher risk of needing a hysterectomy.
The problem arises because the placenta sometimes grows either too low or through the wall of the womb in those women who have had surgery. "It is more likely to grow where the scar is, low down in the womb. That can predispose the woman to bleeding afterwards," said Knight. |
