Your Gut, Your Health: The Complete Guide to Your Gut Microbiome
11 March 2026 • Mark Lewis
Everything you need to know about your gut microbiome in one place. This hub article introduces the Your Gut, Your Health series and links to all six in-depth articles covering testing, symptoms, the gut-brain connection, diet, weight, and dysbiosis.
Your gut is home to trillions of microorganisms that influence everything from immunity to brain health. This article explains what a gut microbiome test actually measures, why testing technology matters, and who stands to benefit most — including why we choose Microba's gold-standard shotgun metagenomics platform at Helix.
Your gut microbiome can signal imbalance long before obvious symptoms appear. Learn the physical and systemic signs of dysbiosis — from bloating and fatigue to skin issues and brain fog — and find out who is most at risk.
Discover how the gut-brain axis links your gut microbiome to mood, anxiety, depression, and cognitive clarity. Evidence-based insights into the neuroscience of gut health and what it means for your mental wellbeing.
A practical, evidence-based guide to improving your gut microbiome — covering dietary fibre, fermented foods, polyphenols, physical activity, sleep, and targeted supplementation, with guidance on personalised approaches.
Discover how gut bacteria influence metabolism, appetite hormones, fat storage, and insulin resistance — and why the microbiome may be one of the most important and overlooked variables in weight management.
A comprehensive clinical guide to gut dysbiosis — what causes microbial imbalance, how it drives disease, how to recognise it, and a practical five-layer framework for restoring and maintaining a healthy, resilient microbiome.
