The gut is one of the most complex systems in the body. Within it lives the intestinal microbiota — an ecosystem of bacteria, viruses, and fungi that perform essential functions.
These bacteria are not passive. They are metabolically active and participate in:
- Food digestion
- Vitamin production (B, K)
- Immune system regulation
- Neurotransmitter production (such as serotonin)
- Inflammation control
When the microbiota is in balance, the body functions correctly. But when it is disrupted (dysbiosis), the effects are systemic. This can cause:
- Intestinal inflammation
- Increased intestinal permeability (‘leaky gut’)
- Immune system activation
- Metabolic alterations
- Changes in mood
That is why symptoms such as anxiety, fatigue, or skin problems may have a gut origin.
Conclusion
The gut does not only digest. It is a regulatory center for the immune, hormonal, and metabolic systems. ma inmune, hormonal y metabólico.
