  Multiple factors explain the growing rate of C-sections, said Dr. John Zweifler, chief of the University of California, San Francisco-Fresno Family and Community Medicine Department.He has done extensive research on C-sections as well as vaginal births after a woman has had a C-section, called VBACs (vaginal birth after Caesarean).
  
  Patient preference is one, with some women requesting them for convenience -- they can schedule the birth and plan time away from work and set up child care for other family members, for instance."In our society, everything is on demand," Zweifler said, adding, C-sections can be "convenient for our lifestyle -- the doctor's and the patient's."
  ...
  And recovery time is typically longer following a C-section, Zweifler said: "It can take four to six weeks to heal tissue."
  
  After a vaginal birth, he said, "it takes time for the uterus to shrink to normal size."But even so, many women are back to normal activities within a few days of a vaginal birth, while those who have a C-section tend to take longer -- sometimes up to six weeks -- due to soreness and pain.
  
  Among the valid reasons for having a C-section, Zweifler said, are the baby is in breech -- or feet first -- position in the womb, twins in the womb aren't lined up head first; or there's evidence of fetal distress or maternal hemorrhaging.
  ...
  "Birth is a very empowering process for women," Zweifler said.Having a C-section "is taking it out of the hands of women and putting it in the hands of a surgeon in a very sterile environment.

  As such, the increased use of Caesarean section runs counter to a basic rule of medicine, said Dr. John Zweifler, chief of the Family and Community Medicine Department at the University of California, San Francisco-Fresno.
  
  That rule?First, do no harm.
  
  "At a fundamental level, it's an intervention," Zweifler said.
  ...
  There are valid reasons for having a C-section, Zweifler said.
  ...
  Zweifler added that he's concerned that the skyrocketing Caesarean section rate will have consequences down the line that cannot be predicted.
  
  "Sometimes, we don't appreciate all the effects of our interventions until years later," Zweifler said."You're getting into uncharted territories here."
  ...
  Studies show that not only is it possible to have a vaginal birth following a previous C-section, but that the risks are roughly the same, Zweifler said.
  
  "There is no difference in outcomes," he said.

  So, as the number of vaginal births after Caesarean sections (VBACS) declined, it would have seemed that infant and maternal death rates would have fallen, too, said study leader Dr. John Zweifler, chief of the University of California, San Francisco-Fresno Family and Community Medicine Department.
  
  Zweifler and his colleagues examined birth data in California from 1996 through 2002, before and after a 1999 guideline to reduce vaginal births after Caesarean sections was adopted.
  ...
  Women who gave birth to low birth weight babies -- less than 1,500 grams, or 3.3 pounds -- had higher newborn death rates with VBAC than a C-section, Zweifler said.But women giving birth to infants of normal weight -- at or above 3.3 pounds -- had similar newborn and mother mortality rates, regardless of whether it was vaginal birth after a C-section or a repeat C-section, the researchers found.
  
  For instance, for newborns weighing 5.5 pounds to less than 8.8 pounds, "there were 0.3 deaths per 10,000 live births before the guidelines [with attempted VBAC], Zweifler said.
  ...
  Complications weren`t considered, Zweifler said, because the only information the researchers had access to was birth certificate data, which don`t list complications.
