What causes irregular menstruation in women? To prevent irregular menstruation in women, remember three points

Generally speaking, a woman's menstrual cycle is 28 to 30 days, but some people's menstrual cycles are as long as 40 days, but as long as there is regularity, it is normal. In addition, the length of the menstrual cycle is easily affected by many factors, so it is normal to be 3 to 5 days early or late. Gynecologists say that if the menstrual cycle this time is 20 days, and the next time is 40 days, and this situation often occurs, some even have menstruation for 1 to 2 days, and then 1 to 2 days after more than 10 days, losing the periodicity, this is irregular menstruation. But when a girl has her first menstruation, because the ovaries have just developed and their functions are not perfect, there will be functional disorders and irregularities. Such a long menstrual cycle problem is not a pathological phenomenon. When the ovaries are fully developed, menstruation will resume its regularity. But some long menstrual cycles may also be caused by diseases, and women need to be extra vigilant. 1. Central nervous system-hypothalamic abnormalities include mental stress, such as reactions caused by mental stress such as environmental changes, excessive tension, and mental shock; there are also weight loss, anorexia nervosa, excessive exercise, drugs, etc. that cause dysfunction or inhibition of the regulation of gonadotropin secretion by the hypothalamus; in addition, there are congenital diseases or brain malformations and tumors that cause abnormal hormone secretion. 2. Pituitary abnormalities refer to abnormal gonadotropin secretion caused by pituitary lesions. There are congenital factors and acquired lesions, such as pituitary tumors. 3. Ovarian abnormalities are caused by congenital ovarian dysplasia or ovarian dysfunction or secondary lesions. Menstrual abnormalities, such as polycystic ovary syndrome, clinical manifestations are oligomenorrhea, irregular menstruation, hirsutism, obesity, etc.; ovarian functional cysts; ovarian tumors, etc., which affect menstruation due to hormonal changes. Then there is severe pelvic infection, which can also damage bilateral ovarian tissue, thereby affecting menstruation, and even permanent amenorrhea, among which tuberculosis lesions are more common. 4. Uterine abnormalities Uterine dysplasia and endometrial destruction can also cause oligomenorrhea or even amenorrhea. Endometrial destruction includes inflammatory factors, such as endometrial tuberculosis; it can also occur after childbirth or after artificial abortion, causing damage to the basal layer of the endometrium or adhesions.
