What possible effect may result from an excess of serotonin in the body?

An excess of serotonin in the body, known as serotonin syndrome, can lead to a variety of adverse effects, one of which includes cardiovascular problems. Elevated levels of serotonin may cause vasoconstriction or increased heart rate, potentially leading to complications like hypertension, tachycardia, or other cardiovascular issues. This heightened activity in the cardiovascular system results from the overstimulation of serotonin receptors that regulate cardiac function and vascular tone.

Other potential symptoms of serotonin excess can include cognitive issues and sleep disturbances, but the distinct relationship between excessive serotonin and cardiovascular complications highlights why cardiovascular problems are a notable concern. Understanding how serotonin interacts with various systems in the body is crucial, as its dysregulation can markedly impact health.
