A new study by researchers in Denmark has found that people who get a high number of antibiotic prescriptions filled each year may be at a higher risk for developing type 2 diabetes.
The study was published in the Journal of Clinical Endocrinology & Metabolism.
By using data from three national health registries in the country, Dr. Kristian Hallundbæk Mikkelsen and some colleagues found that people with type 2 diabetes had 0.8 antibiotic prescriptions filled per year, but people without the condition had 0.5 antibiotic prescriptions filled, notes Medical News Today.
Narrow-spectrum antibiotics (i.e. penicillin V), which are used against specific bacterial infections, were found to have the strongest link to an increase in risk for type 2 diabetes.

"Patients with type 2 diabetes are overexposed to antibiotics compared with matched control persons without diabetes," Mikkelsen told HealthDay. "The overexposure is seen after, as well as 15 years, before the diagnosis of type 2 diabetes."
"Also, it has been suggested that certain gut bacteria may contribute to the impaired ability to metabolize sugar seen in people with diabetes," Mikkelsen added.
However, the Danish researchers did not find an absolute cause-and-effect relationship between antibiotics and type 2 diabetes.
