Faecalibacterium prausnitzii

check icon Optimal Result: 1.29 - 4.79 Healthy Relative Abundance IQR (%).

Faecalibacterium prausnitzii is a key indicator of gut health on a microbiome test panel. As a major butyrate-producing bacterium, it plays a critical role in maintaining the intestinal barrier, regulating the immune system, and exerting anti-inflammatory effects. Low levels of Faecalibacterium prausnitzii are often associated with conditions such as inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), obesity, type 2 diabetes, and various mental health disorders. This bacterium is sensitive to diet, antibiotics, and lifestyle factors, making its presence a valuable marker for assessing gut health and the overall balance of the gut microbiota. Addressing deficiencies in Faecalibacterium prausnitzii through dietary adjustments, probiotics, and prebiotics can significantly contribute to restoring and maintaining gut health.

What does it mean if your Faecalibacterium prausnitzii result is too high?

Elevated levels of Faecalibacterium prausnitzii on a BiomeFx gut test generally indicate a positive finding, as this bacterium is associated with several beneficial effects on gut and overall health:

Significance of High F. prausnitzii Levels

  1. Healthy gut microbiome: F. prausnitzii is one of the most abundant bacterial species in a healthy human gut, making up about 5-15% of the total bacterial population.
  2. Anti-inflammatory properties: This bacterium is known for its strong anti-inflammatory effects, which can help maintain gut health and potentially reduce the risk of inflammatory conditions.
  3. Butyrate production: F. prausnitzii is a major producer of butyrate, a short-chain fatty acid that provides energy for colon cells and has anti-inflammatory properties.
  4. Improved intestinal barrier function: Studies have shown that F. prausnitzii can help strengthen the gut barrier, reducing intestinal permeability ("leaky gut").
  5. Potential protection against certain diseases: Higher levels of F. prausnitzii have been associated with a lower risk of inflammatory bowel diseases (IBD), irritable bowel syndrome (IBS), and colorectal cancer.

Implications for Health

Elevated levels of F. prausnitzii may indicate:

  • A diverse and healthy gut microbiome
  • Good intestinal barrier function
  • Potentially lower risk of inflammatory gut conditions
  • Efficient production of beneficial metabolites like butyrate

Considerations

While high levels of F. prausnitzii are generally considered positive, it's important to interpret these results in the context of overall gut microbiome composition and other health markers. A balanced microbiome is key, and extremely high levels of any single species may not always be ideal.If you have elevated F. prausnitzii levels, it may be beneficial to maintain your current diet and lifestyle habits that support this beneficial bacterium. This typically includes consuming a diet rich in fiber and fermentable carbohydrates, which F. prausnitzii thrives on.

What does it mean if your Faecalibacterium prausnitzii result is too low?

Decreased Levels of Faecalibacterium prausnitzii on a BiomeFx Panel:

Faecalibacterium prausnitzii is a crucial commensal bacterium in the human gut, known for its anti-inflammatory properties and its role in maintaining gut health. Low levels of Faecalibacterium prausnitzii can indicate a disruption in gut microbiota balance and are associated with various health conditions.

Conditions Associated with Low Levels:

  1. Inflammatory Bowel Disease (IBD): Including Crohn's disease and ulcerative colitis.
  2. Irritable Bowel Syndrome (IBS).
  3. Metabolic Disorders: Such as obesity and type 2 diabetes.
  4. Depression and Anxiety: Due to the gut-brain axis connection.
  5. Colorectal Cancer.
  6. Chronic Fatigue Syndrome.
  7. Autoimmune Disorders.

Possible Reasons for Decreased Levels:

  1. Diet: Low fiber intake, high consumption of processed foods, and low intake of prebiotics.
  2. Antibiotic Use: Disrupting the gut microbiota.
  3. Chronic Stress: Affecting gut microbiota balance.
  4. Gastrointestinal Infections: Leading to dysbiosis.
  5. Genetic Factors: Predisposition to lower levels.
  6. Inflammation: Chronic inflammation can negatively impact beneficial bacteria.

Potential Treatment Considerations:

  1. Dietary Modifications:
    • Increase intake of dietary fiber (fruits, vegetables, whole grains).
    • Incorporate prebiotic-rich foods (onions, garlic, leeks, asparagus, bananas).
    • Include anti-inflammatory foods (omega-3 fatty acids, turmeric).
  2. Probiotics and Prebiotics:
    • Specific probiotic strains that support gut health.
    • Prebiotic supplements to feed beneficial bacteria.
  3. Lifestyle Changes:
    • Stress management techniques (meditation, yoga).
    • Regular physical activity.
  4. Avoiding Unnecessary Antibiotics:
    • Judicious use of antibiotics to prevent disruption of gut flora.
  5. Fecal Microbiota Transplantation (FMT):
    • In severe cases, FMT may be considered to restore healthy gut microbiota.

Correlated Biomarkers:

  1. Short-Chain Fatty Acids (SCFAs): Particularly butyrate, which Faecalibacterium prausnitzii produces.
  2. Other Beneficial Bacteria: Such as Bifidobacterium and Lactobacillus species.
  3. Inflammatory Markers: Such as C-reactive protein (CRP) and fecal calprotectin.

Nutrient Associations:

  1. Fiber: Essential for the growth of Faecalibacterium prausnitzii.
  2. Polyphenols: Found in fruits, vegetables, tea, and wine; they support gut bacteria.
  3. Omega-3 Fatty Acids: Anti-inflammatory and beneficial for gut health.
  4. Vitamin D: Modulates the immune system and may influence gut microbiota.

Specific Considerations:

  1. Males vs. Females:
    • Hormonal differences can influence gut microbiota composition.
    • Women might experience more gut-related issues due to hormonal cycles.
  2. Young vs. Old:
    • Young: Early life microbiota establishment is crucial; factors like breastfeeding can influence levels.
    • Old: Aging can lead to a decline in microbiota diversity, including Faecalibacterium prausnitzii.

Addressing decreased levels of Faecalibacterium prausnitzii involves a holistic approach, considering dietary, lifestyle, and potentially therapeutic interventions. Regular monitoring and personalized treatment strategies can help maintain optimal gut health.

What Healthmatters Members Are Saying

5 stars rating

I have been using Healthmatters.io since 2021. I travel all over the world and use different doctors and health facilities. This site has allowed me to consolidate all my various test results over 14 years in one place. And every doctor that I show this to has been impressed. Because with  any health professional I talk to, I can pull up historical results in seconds. It is invaluable. Even going back to the same doctor, they usually do not have the historical results from their facility in a graph format. That has been very helpful.
