10 Serotonin Syndrome Symptoms
Reviewed: Dr. Gromatzky
Symptom #7: Nausea, Vomiting, and Diarrhea
The gastrointestinal system is the largest producer of serotonin in the human body and, as such, high levels of serotonin are directly connected with the normal functioning of the gastrointestinal system.
Serotonin is released in response to food in the lumen, allowing the gut to contract and digest the ingested food. Increased levels of serotonin will lead to various gastrointestinal symptoms such as increased bowel sounds, nausea, vomiting, and diarrhea.
