Gut microbiota:

what it is and how to keep it healthy

What is the gut microbiota:

The gut microbiota constitutes the largest micro-ecosystem in the human body and contributes to physiological health and balance.


Structural functions:
Contributes to the structure and integrity of the intestinal mucosa, as well as to the development of the immune system.

Protective functions:
Protects against the proliferation of pathogens, that are potentially dangerous bacteria.

Metabolic functions:
Promotes metabolic activity allowing the digestion and assimilation of various nutrients, which the body would otherwise be unable to assimilate (carbohydrates, lipids, proteins, polyphenols).

Alterations and causes

The balance between the intestinal microflora, the immune system, and the intestinal mucosa is critical for intestinal health.
Any alteration can cause disorders not only in the gut, but also in other organs or systems.

The main causes of altered intestinal bacterial flora can be functional (motility or post-surgical alterations) or generated by other conditions, such as:

  • malnutrition
  • immunodeficiency
  • older age
  • prolonged therapies (e.g., with antisecretors)
  • antibiotic treatments
  • stress
  • intestinal disorders such as irritable bowel syndrome
