Five times more allergies in C-section babies


For the root cause of allergies, scientists have not yet concluded about the root cause of allergies. A latest study found that the way of birth, genetic and environmental factors induce the allergy constitution.


What scientists wonder is, why do people react differently to the same allergen? Some people may cough, and some may have dry eyes while others suffer from sinusitis? Scientists have not been able to find an answer to this question yet.


Dr. Christine Johnson from the Henry Ford Hospital in USA has been working on allergies since the 1980s. Johnson found that C-section babies is 5 times more probable to be allergic to dust mites and animal hair than natural childbirth.


The baby is in a sterile state in the womb. When he or she passed through the mother’s birth canal, he or she will be exposed to microbial flora and bacteria. Through this process, infants establish a prototype of their own immune system, so that the body learn how to distinguish between beneficial and harmful bacteria – that is, how to fight against harmful bacteria and how to use beneficial bacteria.


The babies born by C-section have not experienced this process, so that their ability to resist allergies is affected. Genetic factors affect the development of allergies too. If parents are not allergic, offspring are usually less susceptible to allergies.
