Small Intestinal Fungal Overgrowth (SIFO) is a condition characterized by an excessive proliferation of fungi, notably Candida species, within the small intestine. This overgrowth can lead to various gastrointestinal symptoms, including bloating, abdominal pain, and diarrhea. It is most often linked with a weak immune system or prolonged antibiotic use. Dr. Elena Ivanina, a distinguished specialist of gut health and SIFO treatment in NYC, helps patients diagnose, understand, and manage this complex condition.
Symptoms:
- Bloating
- Abdominal pain or discomfort
- Gas and flatulence
- Diarrhea or loose stools
- Fatigue and lethargy
- Nausea or vomiting
- Acid reflux or heartburn
- Intestinal permeability (“leaky gut”) symptoms such as brain fog, fatigue
- Fungal infections in other parts of the body, such as fungal skin infections (acne)
Possible root Causes:
- Weak immune system
- Prolonged or frequent use of antibiotics
- Immunosuppressive medications
- Disruption of the gut microbiota balance
- Impaired gut motility or dysmotility disorders
- GI conditions like inflammatory bowel disease (IBD)
- Use of proton pump inhibitors (PPIs) or other medications that alter stomach acid production
- Excessive consumption of refined carbohydrates and sugars, metabolic dysfunction
- Stress and lifestyle factors that affect immune function and gut health

Can diet affect SIFO?
Yes, diet plays a crucial role in managing SIFO. Consuming a diet high in refined carbohydrates, dairy, alcohol, and sugars can promote fungal growth in the gut, exacerbating SIFO symptoms. Therefore, adopting a low-carbohydrate, anti-fungal diet that limits sugar intake can help starve the fungi and reduce SIFO symptoms. Additionally, incorporating probiotic-rich foods and fiber can support gut health and balance the microbiome.
Can SIFO be prevented?
While it may not be entirely preventable, certain lifestyle modifications can help reduce the risk of developing SIFO. These include avoiding unnecessary or prolonged use of antibiotics, managing stress levels, avoiding excessive alcohol use, maintaining a healthy diet rich in fiber and nutrients, and addressing any underlying gastrointestinal issues promptly.
SIFO FAQs
What is SIFO, and how is it different from a systemic yeast infection?
SIFO (small intestinal fungal overgrowth) occurs when fungi, most commonly Candida species, grow excessively in the small intestine and contribute to digestive symptoms. Yeast such as Candida can overgrow in many parts of your body, from your mouth and tongue (“thrush”) to your esophagus (esophageal candidiasis), vagina (vaginal yeast infections), and systemically. Dr. Ivanina can help you understand where yeast is overgrown to guide successful treatment.
How is SIFO officially tested and diagnosed?
The standard for diagnosing SIFO is collecting a fluid sample from the small intestine during an upper endoscopy and testing it for fungal growth. Because this procedure is invasive, Dr. Ivanina also considers your symptoms, medical history, risk factors, and other diagnostic testing, such as blood work and microbiome tests, to identify SIFO.
What treatments are used to eliminate SIFO?
Treatment is personalized and may include diet and lifestyle modifications, natural supplements, and antifungal medications. Dr. Ivanina focuses on restoring a healthier gut environment while addressing underlying contributors and root causes that may contribute to recurring symptoms.
Can taking antibiotics lead to SIFO?
Yes. Antibiotics can disrupt the normal balance of bacteria in the digestive tract, allowing fungi such as Candida to grow more easily in some individuals. However, not everyone who takes antibiotics develops SIFO, and additional factors such as gut motility, immune function, and other digestive conditions may also play a role.
How long does it take to clear a SIFO infection and prevent a relapse?
Recovery depends on the severity of the overgrowth, your health, and whether the underlying contributors and root causes are addressed. While antifungal therapy may help reduce fungal overgrowth, lasting improvement requires treating the factors that allowed SIFO to develop. Dr. Ivanina creates individualized plans to support long-term digestive health and reduce the risk of recurrence.
