The Serotonin-Long COVID Connection: New Research Unveils Potential Link

Low levels of serotonin in the body, caused by traces of the virus remaining in the gastrointestinal tract, may contribute to the development and persistence of long COVID symptoms, according to a study. Researchers found that long COVID patients had different levels of chemicals in their body compared to those who had recovered, with serotonin being the most significant. The low levels of serotonin may lead to cognitive difficulties and memory problems commonly associated with long COVID. Further studies are needed to confirm the causal link between low serotonin levels and long COVID, and to develop potential treatments.
