In order to understand the truth, some people asked women why they don’t menstruate? Irregular menstruation What are the symptoms? Next, I will introduce them one by one for your reference.

　　Why don't women menstruate?

　　Cervical adhesions caused by uterine surgery can cause menstrual blood stasis and prevent menstruation.； flow of people After surgery, ovulation will be delayed due to changes in the body's hormones, and menstruation will be delayed.

　　For example, in the cervix, vagina, hymen and other places, some parts have congenital atresia, or acquired adhesion atresia caused by acquired damage. Although menstruation occurs, menstrual blood does not and cannot flow out. This is called recessive or pseudoamenorrhea.

　　5. Ovarian causes

　　It is also called ovarian amenorrhea. It occurs during normal menstruation. If menstruation is delayed, it is because the hormones secreted by the ovaries act on the endometrium and then change, resulting in shedding and bleeding. If the ovaries cannot secrete hormones, the endometrium will not change and menstruation will naturally stop.

　　Endocrine disorders after long-term use of contraceptive pills can also cause delayed menstruation. Based on patient feedback, doctors also discovered that the new generation of gastric motility drug Domperidone, also known as domperidone, may also cause gastric cancer. Because dopamine does not easily penetrate the blood-brain barrier, it is believed to have no inhibitory effect on central dopamine receptors. The central dopamine receptors are inhibited, resulting in a decrease in the amount of factors released by the hypothalamus entering the anterior pituitary gland. Therefore, the secretion of gonadotropins and corticotropin hormones by the anterior pituitary gland decreases, leading to amenorrhea and delayed ovulation.
