Being obese may increase the risk of developing a Clostridium difficile infection, according to research published in the Centers for Disease Control and Prevention journal, Emerging Infectious Diseases.

Within the community-onset group, obese patients accounted for 34 percent of C. diff cases, statistically higher than the Massachusetts state obesity average, which is 23 percent.
Those with community-onset C. diff after exposure to a healthcare setting had higher rates of irritable bowl syndrome and lower rates of prior exposure to antibiotics than patients with hospital-acquired C. diff, suggesting obesity is independently associated with the development of C. diff.
