Antibiotic Overuse in Kids May Cause Allergies
Doctors have been voicing concerns about the overuse of antibiotics, which can cause harmful bacteria to become resistant to medication. Now researchers have found another reason to make you think twice about asking your child’s doctor for antibiotics: They can lead to allergies. In a comparison of children with and without food allergies, those who had been prescribed antibiotics in the first year of life were 21 percent more likely to be diagnosed with a food allergy by age 3 than those who didn’t receive the meds early in life. The more antibiotic prescriptions the child had, the greater the risk for an allergy. One possible reason is that antibiotics wipe out good bacteria as well as bad, leaving the immune system vulnerable.
