Giving babies antibiotics could lead to obesity: study (Yahoo! News)

Giving babies antibiotics before the age of six months could cause them to be chubby children, according to a study published Tuesday.

"We typically consider obesity an epidemic grounded in unhealthy diet and exercise, yet increasingly studies suggest it's more complicated," said co-author Leonardo Trasande of the New York University School of Medicine.

"Microbes in our intestines may play critical roles in how we absorb calories, and exposure to antibiotics, especially early in life, may kill off healthy bacteria that influence how we absorb nutrients into our bodies, and would otherwise keep us lean."
