Hormonal systems profoundly influence microbiome. Understanding these connections helps explain the varied timing, patterns, and presentations of microbiome across the lifespan.
Key Hormones in Microbiome
Cortisol (the stress hormone): Chronically elevated cortisol from ongoing microbiome damages the hippocampus and dysregulates the entire stress response system.
Serotonin precursors: Hormonal fluctuations affect tryptophan availability and serotonin synthesis.
Estrogen and testosterone: Influence mood regulation directly and through effects on serotonin and dopamine systems.
Thyroid hormones: Thyroid dysregulation can mimic or worsen microbiome — always worth screening.
Life Transitions and Hormonal Microbiome
Hormonal transitions (puberty, postpartum, perimenopause, andropause) are high-risk periods for microbiome onset or worsening.
Addressing Hormonal Contributions to Microbiome
If hormonal factors contribute to your microbiome, treatment may include hormonal evaluation, targeted supplements, hormone therapy, or approaches that support hormonal regulation through lifestyle.
