What is the Origin of Gut Microbiome Endocrinology?

This is a novel, interdisciplinary term born from the convergence of gastroenterology, microbiology, and classical endocrinology. 'Gut Microbiome' refers to the collective genomes and inhabitants of the gut. 'Endocrinology' is the study of hormones. The term formally recognizes the gut microbiota as a crucial, yet previously overlooked, modulator of the entire endocrine network. It signifies a paradigm shift in understanding hormonal regulation.

What is the Mechanism of Gut Microbiome Endocrinology?

The mechanism involves several key pathways, including the microbial production of short-chain fatty acids (SCFAs) that stimulate enteroendocrine cells to release appetite-regulating hormones. Furthermore, the gut bacteria produce enzymes, such as beta-glucuronidase, that deconjugate and reactivate steroid hormones, impacting their enterohepatic circulation and systemic bioavailability. The microbiota also influences the hypothalamic-pituitary-adrenal (HPA) axis, thereby modulating the host's stress response and cortisol dynamics.

Gut Microbiome Endocrinology

Meaning

Gut Microbiome Endocrinology is an emerging field that investigates the complex, bidirectional signaling pathways between the commensal gut microbiota and the host’s endocrine system. It focuses on how microbial metabolites and components directly influence the synthesis, metabolism, and action of host hormones, including sex steroids, thyroid hormones, and satiety peptides. This cross-talk is critical for maintaining systemic metabolic balance, reproductive health, and overall well-being.
