Antibiotics use, particularly antibiotics with greater spectrum of microbial coverage, may be associated with an increased risk of new-onset inflammatory bowel disease (IBD) and its subtypes ulcerative colitis and Crohn’s disease.

The association between antimicrobial treatment and IBD remained when patients were compared with their siblings.
