What is the Origin of Gut-Metabolism Axis?

This term reflects a paradigm shift in endocrinology and gastroenterology, moving beyond viewing the gut as solely an organ of digestion. The realization that the trillions of microbes within the gut function as an "endocrine organ" that produces bioactive metabolites propelled the establishment of this axis concept. Research has increasingly demonstrated the profound systemic effects of gut-derived signals on distant organs.

What is the Mechanism of Gut-Metabolism Axis?

Communication along this axis is mediated by several pathways, including the production of short-chain fatty acids (SCFAs) by the microbiota, which act as signaling molecules in the liver and adipose tissue. Additionally, gut microbes influence the release of key satiety and incretin hormones, such as GLP-1 and PYY, which regulate insulin secretion and appetite control. The integrity of the gut barrier and the subsequent control of low-grade systemic inflammation are also crucial components of this regulatory loop.

Gut-Metabolism Axis

Meaning

The Gut-Metabolism Axis describes the complex, bidirectional communication network linking the gastrointestinal tract, its resident microbiota, and the body’s systemic metabolic processes, including energy balance and glucose homeostasis. This axis highlights how the composition and function of the gut microbiome influence nutrient absorption, hormone production, and inflammatory signaling, directly impacting metabolic health. Disruptions in this communication are increasingly implicated in the pathogenesis of obesity, insulin resistance, and Type 2 Diabetes.
