From the Guidelines
The most effective diet for a patient with C diff is one that supports the restoration of normal gut microbiota, and the current evidence suggests that a diet rich in fiber, with adequate hydration, and avoidance of antimotility agents is recommended. The treatment of Clostridioides difficile infection (CDI) depends on the severity and recurrence status of the infection, and the most recent guidelines recommend the use of oral vancomycin or fidaxomicin as the first-line treatment for initial mild to moderate cases 1. For severe infections, the same vancomycin or fidaxomicin regimens are used, but patients may require hospitalization for intravenous fluids and electrolyte management. In fulminant cases with complications like toxic megacolon or sepsis, vancomycin may be given both orally and rectally, often with intravenous metronidazole, and surgical consultation for possible colectomy 1.
Some key points to consider in the management of CDI include:
- Discontinuing the inciting antibiotic if possible
- Avoiding antimotility agents
- Implementing contact precautions
- Practicing meticulous hand hygiene with soap and water since alcohol-based sanitizers are ineffective against C. difficile spores
- Considering the use of fecal microbiota transplantation (FMT) for patients with multiple CDI recurrences who have failed appropriate antibiotic treatments 1
- Using coadjutant treatment with monoclonal antibodies (bezlotoxumab) to prevent recurrences of CDI, particularly in patients with CDI due to the 027 epidemic strain, in immunocompromised patients and in patients with severe CDI 1
The current evidence suggests that a comprehensive approach to the treatment of CDI, including antibiotic therapy, supportive care, and consideration of FMT and coadjutant treatment, is the most effective way to manage the infection and prevent recurrence. The most recent guidelines recommend a tailored approach to the treatment of CDI, taking into account the severity and recurrence status of the infection, as well as the patient's individual risk factors and medical history 1.
In terms of diet, a diet rich in fiber, with adequate hydration, and avoidance of antimotility agents is recommended to support the restoration of normal gut microbiota. Some specific dietary recommendations include:
- Eating a balanced diet that includes plenty of fruits, vegetables, and whole grains
- Avoiding spicy or fatty foods that can irritate the stomach
- Drinking plenty of water to stay hydrated
- Avoiding antimotility agents, such as loperamide, that can slow down bowel movements and worsen CDI symptoms.

From the Research
Treatment and Management of C diff Infection
- The treatment of Clostridioides difficile (C diff) infection typically involves the use of antibiotics such as vancomycin, fidaxomicin, or metronidazole 2, 3, 4.
- Fecal microbiota transplantation (FMT) has also been shown to be effective in treating recurrent C diff infection 2, 3, 5.
- The use of probiotics, such as Saccharomyces boulardii, may also be beneficial in preventing recurrent C diff infection 2, 5.
Dietary Recommendations
- There is limited research on the specific dietary recommendations for patients with C diff infection.
- A low-fiber or low-residue diet may be recommended in some cases, particularly during the acute phase of the illness or during bowel preparation for diagnostic procedures 6.
- However, the definition and implementation of low-residue and low-fiber diets can be inconsistent, and more research is needed to determine their effectiveness in managing C diff infection.
Prevention of Recurrent C diff Infection
- Several interventions have been shown to be effective in preventing recurrent C diff infection, including the use of fidaxomicin, FMT, and monoclonal antibodies such as bezlotoxumab 3, 5, 4.
- The choice of treatment will depend on the individual patient's circumstances, including the severity of the infection and the number of recurrences 3, 5, 4.
