ICD-10: K63.822

Clinical Description of Small Intestinal Fungal Overgrowth (ICD-10 Code K63.822)

Overview

Small intestinal fungal overgrowth (SIFO) is a condition characterized by an abnormal increase in fungal organisms, particularly yeasts like Candida, in the small intestine. This condition can lead to various gastrointestinal symptoms and may be associated with underlying health issues, such as immunocompromised states or antibiotic use.

Etiology and Pathophysiology

SIFO typically arises when there is an imbalance in the gut microbiota, often due to factors such as:

• Antibiotic Use: Broad-spectrum antibiotics can disrupt the normal bacterial flora, allowing fungi to proliferate.
• Immunosuppression: Conditions that weaken the immune system, such as HIV/AIDS, diabetes, or the use of immunosuppressive medications, can predispose individuals to fungal overgrowth.
• Underlying Gastrointestinal Disorders: Conditions like irritable bowel syndrome (IBS) or small intestinal bacterial overgrowth (SIBO) may also contribute to the development of SIFO.

The overgrowth of fungi can lead to inflammation and damage to the intestinal lining, resulting in malabsorption and other gastrointestinal symptoms.

Symptoms

Patients with small intestinal fungal overgrowth may experience a range of symptoms, including:

• Abdominal pain or discomfort
• Bloating and gas
• Diarrhea or constipation
• Nausea
• Fatigue
• Weight loss

These symptoms can significantly impact the quality of life and may mimic other gastrointestinal disorders, making diagnosis challenging.

Diagnosis

Diagnosing SIFO can be complex and often involves:

• Clinical Evaluation: A thorough history and physical examination to assess symptoms and potential risk factors.
• Laboratory Tests: Stool tests may be conducted to identify fungal organisms, although these tests can sometimes yield false negatives.
• Endoscopic Procedures: In some cases, a colonoscopy or upper endoscopy may be performed to obtain biopsies and directly assess fungal presence in the small intestine[1][2].

Treatment

Management of small intestinal fungal overgrowth typically includes:

• Antifungal Medications: Drugs such as fluconazole or itraconazole may be prescribed to reduce fungal load.
• Dietary Modifications: Implementing a low-sugar and low-carbohydrate diet can help starve the fungi and restore balance to the gut microbiome.
• Probiotics: These may be recommended to help restore healthy gut flora and inhibit fungal growth.

Prognosis

The prognosis for individuals with SIFO largely depends on the underlying causes and the effectiveness of treatment. With appropriate management, many patients can achieve symptom relief and restore normal gut function.
