There’s a new reason for parents to say no to antibiotics for their babies. Study suggests that babies under the age of two who take antibiotics are likely to develop early childhood obesity.

Broad-spectrum antibiotics, which are used to treat wide range of disease-causing bacteria, are usually prescribed by doctors to cure infections. It can easily treat fever, colds, and ear infections. All of which are illnesses prone to children with ages of two to five. Pediatricians tend to prescribe these kinds of antibiotics because a baby’s immune system is not yet strong enough to fight off serious infections.

While these medicines are effective, antibiotics can also eliminate good bacteria in the body. Researchers from the Children's Hospital of Philadelphia and the University of Pennsylvania's Perelman School of Medicine analyzed how antibiotics affect the bacteria in a baby’s digestive system.

The study looked into the health records of 64,580 children from Philadelphia dated between 2001 and 2013. Lead author Charles Bailey said that the bacteria eliminated by antibiotics are responsible for the body’s weight management.

Based on the findings, kids who took four or more antibiotic prescriptions had an 11% chance of becoming obese. Twenty-three percent of the two-year-old kids were overweight while 33 percent of them were overweight at the age of four. Researchers conclude that more exposure to antibiotics leads to higher risk of obesity.

According to pediatrician Sandra Arnold, the study provides evidence on how doctors should be careful in prescribing antibiotics to kids.  However, she admitted that prescribing antibiotic medication is still necessary. Thus, Arnold recommends using narrow-spectrum antibiotics that are effective only against specific types of bacteria.
