Causes of high pituitary prolactin levels

        Elevated pituitary prolactin levels may result from physiological causes such as pregnancy, or pathological conditions such as polycystic ovary syndrome (PCOS) and pituitary adenoma. Treatment should be carried out according to medical advice based on the specific cause. The details are as follows:

　　I. Physiological Causes

　　If the patient is pregnant, the body naturally increases prolactin secretion to support breast development and lactation. This is a normal physiological phenomenon and generally does not require special treatment if no other adverse symptoms are present.

　　II. Pathological Causes

　　1. Polycystic Ovary Syndrome (PCOS)

　　In PCOS, ovarian follicles fail to develop and mature properly, continuously secreting estrogen. This suppresses the synthesis and release of dopamine in the pituitary gland, thereby stimulating the production and secretion of prolactin, leading to elevated levels. It is recommended to follow a physician’s guidance in using medications such as dydrogesterone tablets, medroxyprogesterone acetate tablets, or progesterone capsules for management.

　　2. Pituitary Adenoma

　　During the course of this condition, the tumor may stimulate the pituitary gland to overproduce and secrete prolactin, resulting in elevated prolactin levels. Treatment under medical supervision may include radiation therapy or surgical removal of the tumor.

　　In addition, some patients with depression may experience increased prolactin levels due to long-term use of antidepressant medications. It is advisable to consult a doctor for medication adjustment.
