Gastrointestinal Flora

Meaning

Gastrointestinal Flora, more accurately termed the gut microbiota, refers to the vast, complex community of microorganisms—including bacteria, archaea, viruses, and fungi—that inhabit the human digestive tract. This ecosystem is a critical, dynamic organ responsible for essential metabolic, immune, and endocrine functions. The diversity and composition of this microbial community profoundly influence nutrient absorption, the integrity of the intestinal barrier, and the production of signaling molecules that communicate with the host’s brain and distant organs. Maintaining a balanced flora is central to systemic health and wellness.
