Hello and thank you for posting your medical question on E health forum.
Clostridium difficile , often called C. difficile or C. diff, is a bacterium that can cause symptoms ranging from diarrhea to life-threatening inflammation of the colon. Illness from C. difficile most commonly affects older adults in hospitals or in long term care facilities and typically occurs after use of antibiotic medications.
In recent years, C. difficile infections have become more frequent, more severe and more difficult to treat. Each year, tens of thousands of people in the United States get sick from C. difficile, including some otherwise healthy people who aren't hospitalized or taking antibiotics.
In severe cases, C. difficile causes the colon to become inflamed (colitis) or to form patches of raw tissue that can bleed or produce pus (pseudomembranous colitis). Signs and symptoms of severe infection include: Watery diarrhea 10 to 15 times a day, abdominal cramping and pain, which may be severe, Fever , Blood or pus in the stool, Nausea, Dehydration , Loss of appetite, Weight loss, etc.
Mild illness caused by C. difficile may get better if you stop taking antibiotics. Severe symptoms require treatment with a different antibiotic.
I hope this information helps.
