Ordinarily, only in women after childbirth, breast milk secretion will. However, some unmarried girls will suddenly discover bra occasional pieces on the wet stain trace. If occasionally squeeze a little breasts, you can see similar milk as a white liquid flow out. The reason - say, one should first understand the milk of women on maternity leave after the selection : women breast mainly by the development of ovarian secretion of estrogen and progesterone the effects. Estrogen prompted lobular breast development, progesterone make breast ductal growth. While milk secretion is under the control of the nervous system, through the hypothalamic-pituitary-ovarian shaft of the pituitary prolactin secretion and adjusted to achieve.
The hypothalamus is the regulation of secretion of milk, “Command”, pituitary accept Command directives like “operations Corps”, which according to the hypothalamus signals have prolactin. Usually, women in vivo prolactin levels rarely, only for normal breast development, and fails to arouse milk secretion. After pregnancy, pregnant women the hormone increased the body through the feedback received so hypothalamus pregnancy information and a rapid increase in the secretion of prolactin, before delivery can be achieved in peacetime more than 10 times. Why, then, unmarried girls secrete milk? This is mainly girls in the hypothalamus period will have a “prolactin inhibitory factor,” and so there is no breast milk secretion.
Unmarried girls milk secretion also called “hyperprolactinemia.” Hyperprolactinemia patients, in addition to galactorrhea, are often accompanied by varying degrees of menstrual disorders, severe or even amenorrhea, hair loss, weight gain, headaches, visual impairment, such as genital atrophy symptoms, a group formed to galactorrhea, amenorrhea, infertility, and the performance of major diseases , also known as the “galactorrhea — amenorrhea syndrome.” However, regardless of the severity of symptoms to what extent, mainly because there are excessive prolactin reasons. Can cause hyperprolactinemia many causes, can be roughly divided into the following categories : barriers hypothalamus, pituitary obstacles, primary hypothyroidism, drug factors, such as nerve stimulation.
It should be noted that once discovered they have galactorrhea phenomenon, should go to the hospital in time to do detailed checks. It is noteworthy that hyperprolactinemia with the men and women there have the possibility of infertility and sometimes can lead to sexual dysfunction. Therefore, in the event of galactorrhea am not take it lightly or ignored.
