Hospital. The majority of c. Diff cases occur in the hospital with patients who are taking antibiotics to treat recent infections. Other risk factors include being over the age of 65, colon disease, being in a hospital or nursing home for an extended period of time, have a weak immune system, abdominal or gastrointestinal surgery, or previous history of c. Diff infections.
Antibiotic takers. The primary risk for c. Difficile disease is taking antibiotics which cause dysbiosis and allow overgrowth of this toxin producing bacteria in the gut. Taking the anti-acid drugs called proton pump inhibitors also increase the risk as does being in the hospital when taking antibiotics or anti-cancer chemotherapy.
