The relationship between serotonin, the gut, and the brain

The Crucial Role of Serotonin

Serotonin, commonly known as 5-HT, is a key neurotransmitter that impacts various bodily functions, particularly in the gastrointestinal system, the nervous system, and even the liver. This comprehensive review delves into the intriguing hypothesis that gut microbes significantly influence serotonin levels, shedding light on the complex interactions within our body.

The Impact of Gut Microbes on Serotonin

Extensive research spanning from 1993 to today reveals that changes in gut microbiota can directly affect serotonin signaling. For instance, antibiotic treatments that disrupt gut bacterial balance can also alter serotonin levels. Certain bacteria types have been specifically linked to these changes, highlighting the profound impact of our gut flora on our overall health.

Serotonin’s role extends beyond the gut; it’s pivotal in regulating visceral pain, secretion processes, and the peristaltic reflex which helps move food through the gut. The neurotransmitter’s levels are notably different in various psychiatric disorders, suggesting its broad influence on health.

Serotonin in Gastrointestinal and Liver Health

In some gastrointestinal disorders, symptoms may stem from disruptions either in the central nervous system, directly in the gut, or from an interaction of both, mediated through various stimuli. Additionally, serotonin contributes to liver health by promoting cell growth in conjunction with other factors.

Ongoing Research and Future Directions

While the exact mechanisms of how gut microbes and serotonin interact remain partially understood, the evidence points to a significant link that could influence both gastrointestinal and liver conditions. Understanding these relationships further could open new paths for managing health issues related to the gut and brain.
