Which neurotransmitter may be important for regulating appetite and is linked to depressive disorders?

Serotonin is a neurotransmitter that plays a crucial role in various physiological functions, including the regulation of mood, appetite, and sleep. It is primarily known for its involvement in feelings of well-being and happiness. Research indicates that lower levels of serotonin are often observed in individuals with depressive disorders, linking it to the symptoms of depression.

In terms of appetite regulation, serotonin helps signal feelings of satiety and fullness after eating. When serotonin levels are balanced, they contribute to normal appetite control. However, disturbances in serotonin function can lead to altered eating behaviors, which are commonly seen in depressive disorders where individuals may experience increased or decreased appetite.

This connection highlights the importance of serotonin in both mood regulation and appetite management, making it a critical neurotransmitter in understanding these interrelated aspects of mental health.
