Serving as the "second genome" of the human body, the gut microbiota plays a critical role in the digestion, absorption, and metabolism of both food and medications. The gut microbiome is integral to multiple facets of human health. It facilitates the digestion of complex carbohydrates and fibers that human digestive enzymes struggle to break down. Interacting with the immune system, it contributes to the regulation and balance of immune responses. The microbiome is actively engaged in the metabolism of various compounds, impacting energy extraction from the diet and synthesizing essential vitamins like B vitamins and vitamin K.The gut microbiome serves as a barrier against harmful pathogens by competing for resources and producing substances that impede the growth of potential invaders, while also influencing the production of neurotransmitters, thus playing a role in mood and mental health.
The gut microbiota is constantly changing due to factors like diet, medications, the intestinal environment, immune function, and internal dynamics. This diverse community includes bacteria, viruses, fungi, and other microbes, outnumbering human cells by tenfold. Lifestyle choices greatly affect the microbiome's health, which is crucial given the rise in colorectal cancer cases in individuals under 50, emphasizing the importance of proactive digestive system care.
Common contributors to gut dysbiosis include:
Prolonged antibiotic exposure: Antibiotics can disturb the natural equilibrium of gut microbiota by affecting both beneficial and harmful bacteria.
Chronic stress: Prolonged stress affects gut health by influencing the nervous system and altering the composition of the microbiota.
Gastrointestinal infections: Various pathogens found in the stomach and intestines can disrupt proper digestive function and flora. Common infections include Salmonella, Clostridium difficile, E. coli, Giardia lamblia, Hepatitis A, and H. pylori.
Widespread use of pesticides and herbicides: In agricultural practices, the extensive use of pesticides and herbicides has the potential to modify the makeup of gut microbiota, elevate inflammation within the gastrointestinal tract, and disrupt the absorption of nutrients.
Dietary habits: Diets lacking in fiber, rich in highly processed and refined foods, containing added sugars, artificial sweeteners, unhealthy fats, and having low polyphenol intake, as well as limited food diversity, can influence the diversity of the gut microbiota.
Poor oral health: Insufficient oral hygiene can lead to an increase in harmful bacteria within the oral cavity, potentially allowing them to migrate through the digestive system and impact the composition of the gut microbiome.
Lack of microbial exposure: Reduced exposure to diverse environmental microbes, particularly in early childhood, has been suggested as a potential contributor to gut dysbiosis.
Medications: Certain medications, such as proton pump inhibitors (PPIs), non-steroidal anti-inflammatory drugs (NSAIDs), and antacids, may impact the gut microbiota by altering the acidity and environment of the gut, affecting the growth of different microbial species.
Environmental exposures: Environmental factors, including pollutants and chemicals, may also influence the gut microbiota, with exposure to toxins having direct or indirect effects on the microbial community in the gut.
If gut dysbiosis is a concern, it is recommended to partner with a healthcare practitioner for functional lab testing. This collaborative effort can pinpoint imbalances and provide tailored solutions and support, eliminating the need for guesswork in addressing the issue. A few general steps to support gut dysbiosis concerns would be Molecular Provisions microbiome testing through the GI-Map stool test. This diagnostic test examines the DNA of microbial organisms within a patient's stool sample, offering thorough insight into the composition of a patient's gut microbiome. Seeking guidance from a healthcare practitioner to evaluate your symptoms, health history, and lab results is a valuable step. This collaborative approach can help identify an appropriate course of action to address gut dysbiosis effectively.
