Frequent Antibiotic use raises risk of type 2 diabetes: Study co-author Dr. Kristian HallundbækMikkelsen, of Gentofte Hospital in Denmark, and colleagues published their findings in the Journal of Clinical Endocrinology & Metabolism.

Using data from three national health registries from Denmark, the team monitored antibiotic prescriptions for 170,504 individuals with type 2 diabetes, alongside those for 1.3 million individuals without the condition. From their analysis, the team found that individuals who filled more prescriptions for antibiotics were at greater risk for type 2 diabetes diagnosis.

While a number of antibiotics were linked with increased type 2 diabetes risk, the researchers say the strongest association was for narrow-spectrum antibiotics - antibiotics that are effective against specific bacteria - such as penicillin V.

Mikkelsen notes, however, that further research is warranted to determine exactly what drives the association between antibiotic use and type 2 diabetes.
