A recent study published on the John Hopkins Health alert
s: "People with IBS have significantly lower levels of serotonin in cells lining the stomach. Although serotonin is best known for its role as a mood-boosting brain chemical, it is also involved in many digestive functions and in the perception of pain. In fact, more serotonin is found in the stomach than in the brain, and the GI tract is very sensitive to changes in its serotonin level. The researchers concluded that IBS may arise from abnormalities in serotonin levels responsible for digestive functions."
