The gut and brain are closely interconnected and influence each other.
How intestinal problems affect the psyche
The gut interacts with the brain through the so-called gut-brain axis, a system for transmitting signals between organs.
Microbes in the gut produce neurotransmitters such as serotonin and dopamine, which regulate our mood and emotions.
90% of the happiness hormone - serotonin - is produced by special intestinal cells.
Some types of bacteria that live in the intestines produce short-chain fatty acids, which can enhance the production of serotonin by these cells.
Thus, indirectly, bacteria help maintain a good mood.
The intestines control our emotions, and poor nutrition can cause anxiety and neuroses.
Research has shown that some microorganisms are capable of producing the neurotransmitter gamma-aminobutyric acid (GABA). It is one of the most abundant signaling molecules in the nervous system.
Irritable bowel syndrome (IBS) can cause serious damage to a person's mental health, a new study has found.
How the gut and depression are connected
Stress and dysbiosis worsen mood and affect the risk of developing anxiety and depression.
At the same time, depression can disrupt the balance of the microbiota and lead to the development of inflammation.
Previously, we talked about how loneliness affects mental health.
