Welcome to the tag category page for Gut microbiota!
Gut health refers to the wellbeing of your digestive system, including your stomach and intestines. Poor gut health can lead to various health problems such as inflammation, stomach pain, and even autoimmune diseases. However, there are things you can do to improve your gut health, such as eating fiber-rich and probiotic-packed foods, taking prebiotic or probiotic supplements, and exercising regularly. Drinking enough water and getting enough sleep can also support gut health. Signs of an unhealthy gut include constipation, diarrhea, bloating, and stomach pain. Foods such as whole grains, onions, garlic, fermented foods, miso, and yogurt can also improve gut health. Finally, some research suggests that certain types of gut bacteria can impact your overall health, including your heart health.
The gut–brain axis refers to bidirectional biochemical and neural communication between the gastrointestinal tract and the central nervous system, with gut microbiota acting as a central mediator. Signaling occurs via the enteric nervous system and vagus nerve, immune and inflammatory pathways, enteroendocrine hormones, microbial metabolites and effects on intestinal barrier function. This network links digestion with mood, cognition, stress responses and metabolic regulation, and is implicated in functional gastrointestinal disorders, depression, neurodevelopmental and neurodegenerative conditions, and metabolic disease. Research is advancing rapidly, driving interest in interventions such as dietary modulation, prebiotics and probiotics (sometimes called psychobiotics), fecal microbiota transplantation and targeted microbial therapeutics, but many causal pathways and treatment effects remain unproven or preliminary. Commercial and clinical development faces challenges including variability in individual microbiomes, trial reproducibility, regulatory frameworks and safety. The trend spans pharmaceuticals, diagnostics, nutrition and digital health, and is prompting cross-sector investment in microbiome sequencing, bioinformatics and personalized approaches to brain–gut health.
Postbiotics are beneficial compounds produced by probiotic bacteria in the gut when they digest and break down fibers called prebiotics. They include organic acids, enzymes, bacteriocins, and short chain fatty acids (SCFAs). Postbiotics are considered waste products but offer various health benefits, including immune system support, diarrhea prevention, and reducing symptoms associated with irritable bowel diseases and allergies. Postbiotic skincare aims to balance the skin's microbiome by topping up good bacteria, preventing pathogens and bad bacteria from taking over, which can cause dryness, sensitivity, and other skin issues.
