Hygiene Hypothesis

1 C-Section Babies Prone to Allergies

Babies born by Caesarean section are five times more likely to develop allergies by age two when exposed to common household allergens including dust mites, dogs and cats than babies born vaginally. The Henry Ford Hospital study of 1,258 newborns advances the hygiene hypothesis that early exposure to microorganisms affects the development of the immune system and the onset of allergies. "We believe a baby's exposure to bacteria in the birth canal is a major influencer on their immune system,” says lead author Christine Cole Johnson, Ph.D., MPH who explains that babies born by C-section have microorganisms that may make them more susceptible to developing the antibody Immunoglobulin E. IgE is linked to the development of allergies and asthma.
