Risks of Caesarean Birth

Caesarean Birth carries many of the risks associated with common major abdominal surgery for the woman, but also has associated short and longer term risks for both mother and the baby. For women, the risks include increased possibility of immediate health complications such as hysterectomy and cardiac arrest; reduced levels of satisfaction with the birth; negative impacts on establishing breastfeeding and complications with the placenta in subsequent pregnancies. A growing body of evidence is suggesting that caesarean birth significantly changes the physiology of newborn babies, making their immediate transition to the world more difficult. There is also evidence that caesarean birth can have longer term health impacts on babies, such as increasing the risk of asthma and allergies, Type 1 Diabetes and obesity.

The risks of caesarean birth for the mother include:

  • having to stay longer hospital compared with vaginal birth (NICE 2012);
  • three times the risk of requiring a hysterectomy due to post-partum haemorrhage (NICE 2012);
  • significant increase in the risk of cardiac arrest (NICE 2012);
  • reduced levels of satisfaction with the birth (Hodnett et al. 2012);
  • increased difficulties in establishing and continuing breastfeeding due to a delay in skin-to-skin contact after birth (NICE 2004, Bick 2003).
  • increases the risk of women experiencing all major forms of placental disorders in subsequent pregnancies e.g. placent abruption, placenta praevia and placenta accreta (Klar et al. 2014).

The risks of caesarean birth for the baby include:

Immediate risks include:

  • double the risk of the baby's admission to neonatal intensive care;
  • problems with breathing;
  • not as able to regulate body temperature;
  • increased dificulties in establishing and continuing breastfeeding;
  • alterations to the way genes in the baby's immune system express themselves;
  • altered blood pressure (Hyde et al. 2012).

Longer-term impacts include:

  • increased risk of asthma and allergies (Hyde et al. 2012), gastroenteritis (Hakansson et al. 2003), Type 1 diabetes (Cardwell et al. 2008) and obesity (Goldani et al. 2011, Huy et al. 2012)
  • an increase in the likelihood of having a special educational need if the baby is born at aroud 37 weeks or so weeks compared to babies who are born at 40 weeks (MacKay et al. 2010).

QUICK FACTS

 

 

 

Breathing

 
caesarean birth can impact how well newborn babies adapt after the birth

 

 

 

Breastfeeding

 
Effects from anaesthesia, delayed skin-to-skin contact and the mother's abdominal discomfort can make it more difficult to establish breastfeeding

 

 

 

 

Asthma / Allergies

 

caesarean born babies seem to be at greater risk for asthma and allergies
