How the gut-brain axis affects our health
In our bodies coexist two nervous systems main ones: the central nervous system (CNS) and the enteric nervous system (ENS). And while the former has always been talked about, the centrality of the role of the enteric system is a more recent acquisition. The gut, after all, has a complex neural network, and the quality of communication with the brain is strongly influenced by the state of gut health, particularly in the presence of sub-inflammation.
Common bowel disorders such as irritable bowel syndrome (IBS), often associated with Candida Albicans overgrowth, can increase the risk of emotional, sleep and concentration problems. This close bidirectional relationship between gut and brain regulates not only digestive functions, but also our emotions and mood.
Stress and the gut: a direct link
Our emotional state has a direct impact on the gut. In times of high stress or anxiety, the brain releases cortisol, a hormone that can alter intestinal motility, increase the permeability of the intestinal barrier, and affect mucus production. This can lead to symptoms such as meteorism, constipation, diarrhea and abdominal pain. The microbiota, the collection of bacteria and fungi in our intestines, plays a crucial role in this interaction.
The role of the microbiota and dysbiosis
The microbiota is a key player in gut-brain communication. When its composition becomes imbalanced, it is referred to as dysbiosis, a condition that causes sub-inflammation and can interfere with brain activity. This imbalance has been linked to cognitive disorders, anxiety-depressive syndromes and, in some cases, even autism spectrum disorders.
The microbiota contributes to the production of neurotransmitters such as serotonin and BDNF, a factor that promotes nerve cell growth. At the same time, dysbiosis can weaken the immune system, exacerbating symptoms related to memory problems, migraines and insomnia.
How to improve the health of the gut-brain axis
The balance of the microbiota can be affected by several factors, including:
- Use of medicines
- Unbalanced diet
- Smoking and substance abuse
- Physiological phases such as pregnancy and menopause
Fortunately, dysbiosis is a reversible condition. A diet rich in probiotics and foods that promote the growth of a healthy microbiota can help restore balance. However, in the presence of suspected dysbiosis chronic migraines, insomnia, and difficulty concentrating, it is advisable to check for an intestinal fungal infection.
