Elevated prolactin levels can result from numerous causes. The most common is excessive secretion by the pituitary gland—a polypeptide hormone. Second, hypothyroidism; third, chronic renal failure; fourth, certain medications—such as dopamine receptor antagonists and estrogen; and fifth, stress responses, including intense physical stimuli like vigorous exercise or trauma, which can cause a transient, marked increase in prolactin.
