C. diff (Clostridium difficile) is a bacteria that can enter the body. Symptoms range in severity. Simple diarrhea stands on one end of the spectrum, while dangerous life threatening colon inflammation can be a severe response to this bacteria.
C. diff has traditionally been an issue for the elderly who are staying in long-term care facilities or are spending time in the hospital. It used to only show up after someone has used antibiotics consistently. However, C. diff has recently been showing up in people traditionally not considered at risk. Younger people without antibiotic use are getting it. People who have no exposure to a healthcare facility may find themselves contracting C. diff.
