Excessive dopamine secretion

Excessive dopamine secretion may lead to a series of health problems. The most common symptoms include anxiety, nervousness, insomnia, depression, difficulty concentrating, and memory decline. In addition, excess dopamine may also cause elevated blood pressure, rapid heartbeat, feelings of fear, muscle spasms, itchy skin, nausea, and vomiting. Furthermore, excessive dopamine levels may contribute to metabolic disorders such as obesity, high blood sugar, and high blood lipids. Moreover, prolonged over-secretion of dopamine can lead to psychiatric conditions including schizophrenia, schizoid personality disorder, and bipolar affective disorder.
