The Antibiotic and Asthma Link
When scientists at the university of British Columbia analyzed data from eight studies on antibiotics and asthma, they found that children who received even one dose of antibiotics within their first 12 months had double the risk of developing asthma later on. Each additional dose upped the possibility by 16 percent.
The researchers theorize that use of these drugs decreases natural exposure to germs and overstimulates the immune system's response to allergens, which may lead to asthma.
"There are a lot of childhood viral infections such as bronchitis that are being over-treated with antibiotics. This study is more evidence that antibiotics should be used only when necessary," says lead study author Carlo Marra, PhD.
