The complications include:

• Dehydration: Severe diarrhea can lead to a significant loss of fluids and electrolytes. This condition can cause blood pressure to drop to dangerously low levels.
• Kidney failure: In some cases, dehydration can occur so quickly that kidney function rapidly deteriorates (kidney failure).
• Toxic megacolon: In this rare condition, colon is unable to expel gas and stool, causing it to become greatly distended (megacolon). Left untreated, your colon may rupture, causing bacteria from the colon to enter the abdominal cavity. An enlarged or ruptured colon requires emergency surgery and this may be fatal.
• A hole in your large intestine (bowel perforation): This is rare and results from extensive damage to the lining of your large intestine or after toxic megacolon. A perforated bowel can spill bacteria from the intestine into your abdominal cavity, leading to a life-threatening infection (peritonitis).

Standard treatment for C. difficile infection is oral antibiotics to stop the growth of C. diff. In severe cases, the diseased portion of the colon is removed.

Medication

Antibiotics: The choice of antibiotic is made depending on the severity of the infection and by checking if it is a recurrent infection.

Metronidazole . Vancomycin

Probiotics: To restore the growth of healthy bacteria in the intestine.

Saccharomyces boulardii
