Caesarean Section and IVF promote asthma

September 8, 2013 10:21 pm

A recent UK study has highlighted the link between In vitro fertilization (IVF) and delivery of babies via Caesarean Section (C section) with increased incidence of asthma and allergies. Babies born by C section have a 59% higher risk of developing asthma than if born by vaginal delivery.   IVF babies are more likely to be born by C section because the pregnancies are very closely monitored and more risky.  It is well documented in the Hygiene Hypothesis that vaginal birth will colonise the newborn’s gastrointestinal tract with the mothers natural bacteria which stimulate the immune system naturally to be “non-allergy” prone. Probiotics taken in pregnancy and by the infant also help colonise the bowel with “good” bifidobacteria. Babies born by C Section also have less fluid squeezed out of their lungs at birth and may temporarily develop “wet lung syndrome” which might further increasing risk of respiratory problems. After C Section, mothers are also less likely to establish breastfeeding.
