Menstruation, every normal woman always comes to "relatives" for a few days every month. The normal cycle is 22-35 days, but a few people are much longer than the normal cycle. Why does this lead to this? The following is my introduction to the reasons for your long menstrual cycle. I hope it can help you.
There are many reasons for women's long menstrual cycle, specifically as follows:
1. Endometriosis: This is often caused by excessive menstrual cycle or prolonged menstrual period due to affecting the contraction of myometrium or endometrial enhancement. The placement of birth control device is also easy to cause prolonged menstruation.
2. Uterine leiomyoma: especially submucosal leiomyoma, due to the expansion of uterine cavity, its contraction is abnormal, which can lead to excessive menstrual cycle and long menstrual period.
3. Uterine dysfunctional bleeding: such as anovulatory dysfunctional uterine bleeding and irregular shedding of endometrium, menstrual period is prolonged due to endocrine dysfunction.
4. Chronic uterine hypertrophy: due to pelvic congestion, ovarian estrogen continues to increase, resulting in hypertrophy of uterine myometrium, resulting in excessive menstrual cycle and long menstrual period.
Pelvic inflammation, intrauterine femoral polyps and uterine inflammation all cause excessive menstrual cycle and prolonged menstruation due to poor intrauterine femoral blood circulation, degeneration and necrosis or pelvic congestion.
5. Blood diseases: such as thrombocytopenic purpura and aplastic anemia, which are often accompanied by menstrual cycle. If there is serious uterine bleeding, the menstrual period will be prolonged. Others, such as chronic anemia, chronic hepatitis, liver cirrhosis and nephritis, can make the blood vessel wall fragile, increase the permeability and cause bleeding.
The normal menstrual cycle is 22-35 days, with an average of 28 days. Under normal circumstances, it is normal for menstruation to be advanced or delayed for about a week.
The menstrual cycle of women is generally 28 ~ 32 days. It is normal to advance or delay about a week. The length of menstrual cycle varies from person to person. But if you go beyond this category, you have to pay attention to it.
There are many reasons for the long menstrual cycle, including genetic factors, endocrine problems, immune problems, psychoneurological factors, tumors, drug use and so on. If the interval between menstrual cycles is often as long as 35 days or more, it is recommended to go to the hospital for relevant examination, identify the possible causes, and treat the causes in order to achieve better results. Of course, if there are only 1 ~ 2 times of menstrual delay and no other abnormalities are normal, this does not belong to the category of menstrual diseases and there is no need to worry.
In addition, at menarche, because the ovary is in the developing stage and its function is not perfect, there will be functional disorder and irregularity, resulting in abnormal menstrual cycle; Perimenopausal women will also have the phenomenon of delayed menstrual cycle, which is caused by the gradual decline of ovarian function and the disorder of hormone secretion. Both cases are normal and there is no need to worry.
For women with long menstrual cycle, the calendar method can be used, or the change of leucorrhea can be observed to calculate the ovulation period.
Calendar method: it should be calculated according to the menstrual cycle of the previous 6 ~ 12 months.
The shortest period (days) - 21 days, and the previous safety period is ahead.
The longest period (days) - 10 days, followed by the post safety period.
For example, the shortest menstrual cycle is 30 days and the longest is 38 days. Subtract 21 from the shortest menstrual cycle (i.e. 30-21 = 9) and 10 from the longest menstrual cycle (i.e. 38-10 = 28). Therefore, the 9th to 28th days after menstruation belong to ovulation period.
Observe the changes of leucorrhea: generally, the quality and quantity of leucorrhea change with the menstrual cycle. At the beginning of menstruation, the leucorrhea is white, small in amount and in paste shape; At the time of ovulation, affected by the secretion of cervical glands, leucorrhea increases, which is transparent, slightly sticky and egg white, and can stretch to about 10cm; 2 ~ 3 days after ovulation, leucorrhea becomes turbid, thicker and less.
