Scientific Sources: 23

Summary

Fecal matter, also known as feces or stool, is the solid or semi-solid waste product of digestion discharged from the body via the anus or cloaca [34]. While generally considered a waste product, fecal matter has found uses in medicine, agriculture, and even construction [34].

What it is

Fecal matter consists of undigested food, bacteria, metabolic waste products, and dead epithelial cells [34]. Its characteristic odor is due to compounds like skatole and thiols [34].

Common uses

  • Fecal microbiota transplantation (FMT) for treating Clostridium difficile infections [15]

  • Fertilizer and soil conditioner in agriculture [34]

  • Fuel source when dried [34]

Public Perception

Anxiety level

The idea of using fecal matter, especially in medical treatments or as an ingredient, can evoke feelings of disgust and anxiety [24], [28]. However, this is often balanced by an understanding of its potential benefits and the scientific rigor behind its applications [1], [4].

Cultural claims

  • In ancient China, "yellow soup" made from fecal matter was used to treat severe diarrhea [17], [33]

  • Camel feces were used by German soldiers in World War II to treat bacterial dysentery [17], [35]

Source sentiment

Sources generally present fecal matter objectively, acknowledging its potential benefits in specific contexts while also recognizing its association with disease and waste [14], [15].

History

Timeline

300

Ge Hong in China describes using 'yellow soup' (fecal matter) to treat severe diarrhea [33]

1917

Alfred Nissle isolates a strain of E. coli from feces, laying the groundwork for fecal transplantation [35]

1958

Eiseman et al. publish a report on treating antibiotic-associated diarrhea with FMT via retention enemas [32], [33]

2011

The Mayo Clinic in Scottsdale, Arizona, performs its first fecal microbiota transplant [24]

2013

Researchers in the Netherlands halt a C. diff clinical trial early due to the high cure rate of FMT compared to antibiotics [24]

2023

The FDA approves Vowst, the first orally administered fecal microbiota product for the prevention of recurrent Clostridioides difficile infection [18]

Origin

Treatment of food poisoning and severe diarrhea in ancient China [33]

First appeared: 300

Science

Key findings

  • FMT has a high success rate in treating recurrent Clostridium difficile infection (CDI) [24]

  • FMT may improve rates of clinical remission, clinical response, and endoscopic remission in active Ulcerative Colitis (UC) [7]

  • Adverse events associated with FMT are mostly mild and self-limiting [15]

Studies

Lack of genotoxicity and subchronic toxicity in safety assessment studies of _Akkermansia muciniphila_ formulation

_Akkermansia muciniphila_ lacked mutagenic and genotoxic potential in nonclinical studies and was not toxic to rats at tested doses [1]

Safety evaluation of Akkermansia massiliensis sp. nov. DSM 33459

_Akkermansia massiliensis_ DSM 33459 did not produce any evidence of toxicity in rats after 28- or 90-days of exposure [4]

Adverse events in fecal microbiota transplantation: a systematic review and meta-analysis

Serious adverse events related to FMT developed in less than 1% of patients, with minor adverse events including infrequent self-limited gastrointestinal and systemic discomfort [16]

Safety status

Fecal microbiota transplantation (FMT) is generally considered safe for treating recurrent Clostridioides difficile infection (CDI) [5], [16]. However, there are potential risks, including the transmission of infectious agents and adverse events such as diarrhea and abdominal discomfort [15], [16].

Nuance

While FMT is promising, more research is needed to fully understand its long-term effectiveness and safety, as well as its potential applications for conditions beyond CDI [5], [6].

Alternatives

Probiotics

Probiotics can help restore the balance of gut bacteria, though their effectiveness may vary depending on the specific condition and strains used [22]

Where to find: Available in supplement form or in fermented foods like yogurt and kefir [Source 22]

High-fiber diet

A diet rich in fiber can promote healthy bowel movements and support the growth of beneficial gut bacteria [41]

Where to find: Fruits, vegetables, whole grains, and legumes [Source 41]

Avoidance tips

  • Practice proper food handling and hygiene to prevent foodborne illnesses [45], [48]

  • Avoid unnecessary antibiotic use, as it can disrupt the gut microbiome [10]

  • Consult with a healthcare professional for appropriate diagnosis and treatment of digestive disorders [28]
