A new study shows that exposure to antibiotics early in life (1st year) predicts the occurrence of asthma later on. The evidence seems to suggest that treating non-respiratory infections with antibiotics will double the risk of asthma.

Furthermore, absence of a dog during the birth-year doubled asthma risk among children taking multiple courses of antibiotics.
“Dogs bring germs into the home, and it is thought that this exposure is required for the infant’s immune system to develop normally. Other research has shown that the presence of a dog in early life protects against the development of asthma,” said Dr. Kozyrskyj. “Exposure to germs is lower in the absence of a dog. The administration of an antibiotic may further reduce this exposure and increase the likelihood of asthma development.”
