Gut Microbiome
Also known as: Intestinal Flora, Gut Bacteria
The complex community of microorganisms living in the digestive tract that influences digestion, immunity, and overall health.
FULL EXPLANATION
The gut microbiome consists of trillions of bacteria, viruses, fungi, and other microorganisms living in the gastrointestinal tract. These organisms collectively weigh 2-5 pounds and contain more genetic material than the human genome.
The microbiome plays critical roles in digestion, vitamin synthesis, immune function, inflammation regulation, and even mental health through the gut-brain axis. Microbiome composition is influenced by diet, antibiotics, stress, and other lifestyle factors.
WHY IT MATTERS
Gut microbiome health is linked to immune function, mental health, metabolic health, and disease risk. It's increasingly recognized as a key mediator of overall health.
HOW TO IMPROVE
Support microbiome health through diverse fiber intake, fermented foods, limiting processed foods and artificial sweeteners, managing stress, and avoiding unnecessary antibiotics.
NORMAL RANGES
Microbiome assessment is complex. Diversity (variety of species) is generally positive. Specific bacteria ratios and metabolite production are active research areas.
