High prolactin may affect the body with some physiological dysfunctions, osteoporosis, and intracranial hemorrhage. Prolactin is a polypeptide hormone secreted by specialized cells concentrated on both sides of the posterior pituitary gland and originates from the same cells as growth hormone. If prolactin exceeds the normal range, it may cause a series of abnormal reactions in the body, and it is recommended to pay attention to it in time. 1. Physiological dysfunction: If there is high prolactin, it may cause amenorrhea, breast milk overflow and infertility, which will have a greater impact on women’s normal life. 2. Osteoporosis: high prolactin may also lead to calcium and phosphorus absorption disorders, which may lead to osteoporosis. 3. Intracranial hemorrhage: high prolactin for a longer period of time may also cause intracranial hemorrhage, acute stroke, etc., and in severe cases, headache and nausea may be caused by compression of cerebral nerves. If the high prolactin test results are confirmed, it is recommended to follow the doctor’s instructions for standardized treatment as soon as possible to reduce the adverse effects of the disease.
