Two reasons for lactation in adolescent girls

　　Generally, girls with normal development will have menstruation from the age of 13 to 18, until the reproductive organs mature. This physiological period is called puberty. During this period, in addition to menstruation, girls' breasts, which are secondary sexual characteristics, have obviously developed. There are acinas and glandular ducts inside the breast. The acinar cells have the function of lactation, and the glandular ducts are the pathways for milk. These two structures are secreted by women's ovaries female They develop and grow under the stimulation of hormones (also called hormones).

　　Two reasons for lactation in adolescent girls

　　Breasts do not secrete milk during development. The reason should start with the source of prolactin. Prolactin is produced from an endocrine gland in the human brain, called the cells of the pituitary gland (about one gram in size, shaped like a broad bean). However, it is also controlled by the prolactin inhibitory factor secreted by the hypothalamus, which limits the secretion of prolactin by the pituitary gland. Therefore, lactation is a special function of maternal childcare. Most women, especially adolescent girls, do not have lactation function.

　　Lactation in adolescent girls is an abnormal phenomenon. There are two reasons: first, a prolactin gonad tumor has occurred in the pituitary gland; second, although a prolactin tumor has not occurred, because the pituitary gland cells are stimulated by the prolactin-promoting factor secreted by the hypothalamus, excessive prolactin secretion is called hyperprolactinemia. People with this disease are often accompanied by amenorrhea symptoms.

　　Further diagnosis can be made through cranial CT imaging or MRI and measurement of serum prolactin levels. If there is a tumor, it can be treated with Gamma Knife, and it can be cured without craniotomy: If it is not a tumor, but just hyperprolactinemia, you can take bromocriptine, but it must be taken under the guidance of a doctor.
