Antibiotic-associated Colitis—C difficile
Antibiotics can kill good bacteria in the large intestine. They do not kill C. diff . Instead, C. diff grows with no control and makes toxins. This bothers the lining of the intestine and causes swelling.
This problem happens in people who use antibiotics. It is also more common in older adults and people staying in care centers.
Other things that may raise the risk are:
- Being very sick
- Having a weak immune system
- Using medicines that reduce stomach acid
- Having other digestive problems, such as Crohn disease or ulcerative colitis
- Past surgery on the digestive system
Problems may be:
- Watery stools (poop) that may have mucus in it
- Belly pain
- Lack of hunger
The doctor will ask about symptoms and past health. A physical exam will be done.
Tests may include:
- A stool sample to look for signs of infection.
- Blood tests to look for signs of infection
- A colonoscopy to see inside the large intestine (rarely needed)
- A CT scan to view the large intestine
The goal is to treat the infection. Options are:
- Stopping antibiotics—or switching to one that treats this infection
- Having a stool transplant from a healthy donor—to balance bacteria in the intestine
- Surgery to remove intestine that has a lot of damage
