If your children were born by c-section, they seem to be more at risk for allergies.
Researchers at Henry Ford Hospital suggests c-section babies are five times more likely to develop allergies than babies born naturally when exposed to high levels of common allergens in the home.
Doctors think this risk has to do with what a baby is exposed to during natural birth, "When the baby goes through the birth canal, it's exposed to a lot of the mother's bacteria, which is thought to be very beneficial to the baby's immune system. but when they're born by c-section, they don't get that exposure." Dr. Johnson says c-section babies have a pattern of at risk micro-organisms that may make them develop antibodies to allergens.
More than 1,200 newborns were studied between 2003 and 2007 for this research. Doctors evaluated the children at one month, six months, one year and two years.
