Patient's question:
Female, 27 years old, nulliparous, no miscarriage, mainly with low menstrual volume, lasting only one day each time, but with a regular cycle, occasionally with dysmenorrhea, lasting for about a year.Doctor's answer:
Prolactin, also known as luteinizing hormone, is one of the hormones secreted by the pituitary gland. During the late stages of pregnancy and lactation, women experience a surge in prolactin secretion to promote breast development and lactation. In non-pregnant women, the highest prolactin level in the serum generally does not exceed 20 ng/mL. If the prolactin level in the blood is excessively high, it is referred to as hyperprolactinemia. These individuals often exhibit symptoms such as breast tenderness, galactorrhea, infrequent menstruation, or even amenorrhea. Therefore, it is sometimes also called the galactorrhea-amenorrhea syndrome. In patients with hyperprolactinemia, approximately 1/4 are caused by pituitary tumors, while others may result from dysfunction of the hypothalamus, pituitary gland, hypothyroidism, renal insufficiency, other malignant tumors, chest wall injuries, or drug effects. When prolactin levels are excessively high in the body, they can inhibit the secretion of gonadotropins by the pituitary gland and directly affect the synthesis of sex hormones in the ovaries, leading to low serum estrogen levels. This can disrupt ovarian function, reduce ovulation, or cause anovulatory galactorrhea, and even amenorrhea, resulting in infertility. It is recommended that you seek detailed examination and diagnosis at a specialized hospital for symptomatic treatment and do not miss the best time for treatment.
