Scientists have found a link between the use of oral antibiotics and the risk of Parkinson's disease. They suggest that the connection could be due to the drugs' impact on gut microbes.
The findings also suggest that up to 15 years can elapse between antibiotic exposure and the emergence of any Parkinson's disease symptoms.
The strongest links were for macrolides and lincosamides.
Doctors prescribe oral dosages of these common antibiotics to fight a range of microbial infections.
People with intestinal conditions such as irritable bowel syndrome, constipation, and inflammatory bowel disease have a higher risk of Parkinson's disease.
