Hyperprolactinemia is a dysfunctional disease of hypothalamus-adenohypophysis-ovarian gonad axis. Prolactin secretion is influenced by many factors, so the causes of hyperprolactinemia are complicated, mainly including: 1. Physiological factors: pregnancy, postpartum and lactation, diet, emotional tension and strenuous exercise can all cause hyperprolactinemia. 2. Functional or idiopathic factors: Idiopathic hyperprolactinemia is caused by abnormal regulation of pituitary lactation cells by hypothalamus. I wish you the best of health!
