Podcast: How Your Gut Biome Changes From Birth to Old Age

From the moment of birth through childhood development, adulthood, and into old age, the microbiome undergoes dramatic compositional and functional shifts. Understanding these changes is essential for age-appropriate clinical guidance.

Key Topics Covered

• Birth and early colonisation: vaginal vs. caesarean delivery; breast milk oligosaccharides as selective prebiotics; the critical window of immune programming.
• Childhood and adolescence: the impact of antibiotic exposure; dietary transitions and microbial diversification.
• Adulthood: stabilisation of the microbiome; dominant influence of diet, stress, and medications; pregnancy-associated microbiome changes.
• Ageing: reduced microbial diversity; links to frailty, cognitive decline, and immune senescence.

Longitudinal microbiome tracking allows practitioners to observe how a patient's microbiome evolves over time, identify concerning trajectories early, and intervene when the opportunity to modify outcomes is greatest.
