Some people call menstruation as “aunt”, some people come to menstruation is called “bad luck”, menstruation menstruation, should be month to month, if menstruation does not come according to the month or a long time, what to do? When the follicles are mature and in a normal state, there are regular, cyclical changes in the ups and downs of estrogen and progesterone, and then there is the cyclical shedding and growth of the endometrium, that is, menstruation. If the menstrual cycle is irregular, it is actually indicative of irregular ovulation. The end result of irregular ovulation is that one is not easy to get pregnant, and the other is that the endometrium is prone to lesions. Therefore, if you experience menstrual cycle disorders, you should seek prompt treatment. In women of reproductive age, the most common cause of irregular ovulation is polycystic ovary syndrome; in perimenopausal women, it is mainly due to low ovarian function and there are no more available eggs; in adolescent women, it is often due to immaturity of the nervous system that regulates menstruation. Therefore, the treatment options differ for the different causes of irregular menstrual cycles. In addition to irregular menstrual cycles, another type of menstrual disorder is irregular menstrual flow, which mainly includes prolonged periods and excessive menstrual flow. Generally, the period does not exceed 7 days and the volume does not exceed 80 ml. Endometrial polyps, submucosal or intermuscular fibroids, adenomyosis, ovulation abnormalities, endocrine system disorders, and hematologic disorders may cause this condition and require consultation for differential diagnosis and treatment. A small number of women experience short periods or low menstrual flow, meaning periods of less than 3 days and menstrual flow of less than 5 ml, and the main cause of this may be related to endometrial damage or adhesions. Another condition, sudden loss of menstruation, is to rule out pregnancy. Irregular vaginal bleeding can also occur in early pregnancy if there is a condition such as preterm miscarriage, and this is not a menstrual disorder. Under normal menstrual conditions, ovulation should occur once a month. If you try to conceive by having intercourse during ovulation, the probability of getting pregnant is about 30% in one month and about 90% in a year. The remaining 10% that do not get pregnant are called infertility. If ovulation is irregular, the number of ovulations in a year is reduced and ovulation is not easily found, then the chance of pregnancy is greatly reduced. Also, the endometrium is not suitable for embryo implantation when it is in abnormal proliferation for a long time, and the probability of pregnancy is reduced. As you can see, menstrual disorders should be treated aggressively for women who want to have children. It is not “bad luck” to have a period, but rather it is a good thing to have a period on time, and it should be accepted with a positive attitude.
