Clostridioides (Clostridium) difficile Infection
C diff Infection
The infection is caused by the C diff bacterium. It makes toxins as it grows. This bothers the lining of the intestine.
The intestines have a healthy balance of bacteria that help with digestion. Antibiotics can disturb this balance by killing some bacteria which lets others grow in their place. C diff may be able to grow after certain antibiotics.
The infection can also spread:
- From direct contact with an infected person
- By touching surfaces with the spores of the bacteria and then touching your mouth
This problem is more common in older adults. Other things that may raise the risk are:
- Recent antibiotic use
- Weakened immune system
- Recent hospital stay
- Having intestinal diseases
- History of prior C diff infection
- Use of proton pump inhibitors
Problems range from mild to severe and may be:
- Watery diarrhea
- Belly pain or cramps
- Lack of hunger
The doctor will ask about your symptoms and health history. A physical exam will be done.
Common tests are:
- Stool tests to look for signs the bacterium and its toxins
- Blood tests to look for signs of infection
Rarely, the intestine may need to be viewed to look for changes. This can be done with an endoscopy.
People who have C diff but do not have symptoms do not need to be treated.
The goal of treating people who do have symptoms is to treat the infection. Choices are:
- Stopping or changing antibiotics that may have caused the infection
- Using specific antibiotics to treat the infection
- A fecal microbiota transplant (FMT) to place stool from a healthy donor into a person's intestines to restore a healthy balance of bacteria
- Surgery, such as:
- Partial colectomy—The affected part of the colon is removed. The two healthy ends are joined.
- Illeostomy with irrigation—The small intestine is brought through the abdominal wall to allow stool to leave the body. A liquid is used to flush the colon.

- Cleaning surfaces
- Using probiotics from food or supplements
