Women will menstruate every month. The duration of menstruation is generally 3-7 days, and the amount of menstruation should be between 20 ~ 60ml. If the menstrual period is too long, it is an abnormal phenomenon. Women's prolonged menstruation may be related to gynecological diseases. The following is my introduction to the pathological reasons for your long menstrual period. I hope it can help you.
1. Uterine leiomyoma: suffering from uterine leiomyoma, especially submucosal leiomyoma, will expand the uterine area and affect uterine contraction, resulting in increased menstrual volume and delayed menstruation of women.
2. Uterine polyps: due to the long-term stimulation of chronic cervicitis, polyps will slowly form, and uterine polyps can easily lead to bleeding symptoms in women's body, such as excessive menstruation, prolonged menstruation, etc.
3. Pelvic inflammation: gynecological diseases such as pelvic inflammation and endometritis will cause menorrhagia and prolonged menstruation due to poor blood circulation of femoral blood in the uterus, degeneration and necrosis or pelvic congestion.
4. Chronic uterine hypertrophy: Patients with pelvic congestion, sustained growth of ovarian estrogen, resulting in hypertrophy of uterine myometrium, resulting in excessive menstruation and long menstrual period.
5. Endometriosis: Patients with this kind of disease often suffer from excessive menstruation, prolonged menstruation and severe dysmenorrhea due to affecting the contraction of uterine myometrium or endometrial thickening.
6. Uterine dysfunctional bleeding: such as anovulatory dysfunctional uterine bleeding and irregular shedding of endometrium. These diseases will cause excessive menstruation due to abnormal endocrine function.
1. menstrual cycle
The menstrual cycle of ordinary women is 28 ~ 30 days, but some people have a menstruation in 40 days. But as long as there is regularity, it is normal. In addition, menstruation is easy to be affected by many factors, so it is normal to advance or mistake 3 ~ 5 days later.
If the menstrual cycle is 20 days this time and 40 days next time, and this often happens, some even menstruate for 1 ~ 2 days, and then come for 1 ~ 2 days after more than 10 days, losing periodicity, which belongs to irregular menstruation. At menarche, because the ovaries are just developing and the function is not perfect, there will be functional disorder and irregularity. This is not a pathological phenomenon.
2. Menstrual period (also known as menstrual period)
Women's menstrual period is about 2 ~ 5 days. The general law of menstruation is that there is not much menstrual blood on the first day, it increases on the second and third days, and then decreases gradually until the menstrual blood is clean. This is because the first day of endometrial abscission has just begun, the second and third days of endometrial abscission increased, the amount of bleeding also increased, the uterus was stimulated, strengthened contraction, and a large amount of menstrual blood was discharged.
After some people's menstrual blood is clean, a little comes again in a day or two. It is commonly known as "menstrual blood turning back". This is not a disease, but a normal phenomenon. However, some women have menstrual periods of 10 to 20 days, with endless menstruation; Some menstrual periods are very short and just pass in a flash. Both phenomena are abnormal.
3. Menstrual blood volume
The amount of women's menstruation varies from person to person, generally 20 ~ 100 ml. Generally, change sanitary napkins or paper 3 ~ 5 times a day, even if it is normal. If the amount of menstrual blood is too much, changing a sanitary napkin or paper will soon get wet again, and even the menstrual blood will flow down the leg, which is not normal.
Excessive menstrual blood may be functional uterine bleeding caused by excessive mental tension, environmental changes, malnutrition and metabolic disorders. Excessive menstrual blood for a long time will cause anemia. The cause should be found out and treated. Of course, if there is too little menstruation due to abnormal uterus and ovary or systemic diseases, this situation is also abnormal, and you should see a doctor in time.
Excessive menstruation is common in adolescent girls. The main reason is that in the period of puberty, the ovarian function is not yet fully mature. At this time, part of the menstruation belongs to anovulation. No ovulation, no corpus luteum, no corpus luteum, lack of progesterone.
Therefore, the endometrium can only be in the proliferation stage, but can not reach the perfect secretion stage, so that the endometrium falls off incompletely and affects the contraction of the uterus, resulting in excessive menstrual blood. If this situation does not attract attention, over time, anemia symptoms such as pale complexion, fatigue and dizziness may occur, and medical treatment should also be sought.
4. Menstrual blood color
Normal blood is dark red, mixed with exfoliated endometrial fragments, cervical mucus and vaginal epithelial cells, without blood clots. If the menstrual blood is as thin as water, only a little pink or black and purple, it is abnormal. If the menstrual blood is completely clotted and abnormal, and there may be other bleeding parts, seek medical treatment as soon as possible to ensure good health.
Women's physical constitution and physical characteristics are relatively special, and many parts are also fragile. Therefore, we must pay attention to self-examination and pay attention to the changes of our body in life, especially whether menstruation is normal or not!
How to calculate menstrual cycle? As a woman, she should know more about this. Accounting for her menstrual cycle is a necessary skill, so as to better understand her physical health.
The calculation of menstrual cycle should include the time of menstruation. It is the beginning of menstrual cycle from the first day of menstruation. The interval between two menstruations is the menstrual cycle. Some women also use menstrual cycle calculator to calculate menstrual cycle. Menarche generally starts at the age of 13-14, starting at the earliest at the age of 11 or at the latest at the age of 15, which indicates that women's ovarian function is mature, that is, they have fertility. Normal menstruation is periodic. Menstrual cycle refers to the time between the first day of two menstruations.
When calculating the menstrual cycle, some women calculate the time from the clean menstruation to the next menstruation, which shortens the menstrual cycle. Generally, women in childbearing period should have menstruation once a month if they are not pregnant. Clinically, some women tell the doctor that their menstruation is abnormal and they have menstrual cramps twice a month. In fact, it is normal to calculate carefully again that menstruation comes once at the beginning and end of the month. The normal menstrual cycle is 28-35 days. The length of menstrual cycle varies in different women. It is considered to be in the normal range if it occurs 7-10 days in advance or after mistake. As long as a certain regularity can be maintained, it can not be considered as irregular menstruation. The menstrual cycle is divided into four stages, including follicular period, ovulation period, luteal period and menstrual period. The menstrual cycle is also called "ovarian cycle".
1. Follicular period: the follicular period is from the first day of menstruation to the day of ovulation. During this period, under the influence of follicle stimulating hormone, the concentration of estrogen hormone in the body increases, the follicles gradually mature and the endometrium thickens.
2. Ovulation period: ovulation period refers to the process in which egg cells and surrounding cumulus granulosa cells are discharged together. Women's ovulation date is generally about 14 days before the next menstruation.
3. Luteal phase: luteal phase refers to the period from ovulation to the day before menstruation. Under the influence of luteal stimulating hormone, the ovary secretes luteal hormone to maintain the thickened endometrium, so as to facilitate the implantation of fertilized eggs. If there is no implantation of fertilized eggs, the endometrium will disintegrate, and the menstrual cycle will end with menstruation.
4. Menstrual period: the duration of each menstruation is called menstrual period, which is generally 2-8 days, with an average of 4-6 days. Generally, there are no special symptoms during the menstrual period, but during the menstrual period, due to pelvic congestion and the role of prostaglandins, some women will have discomfort of lower abdomen and lumbosacral falling or uterine contraction pain, and may have gastrointestinal dysfunction symptoms such as diarrhea. A few women may have headaches and mild neurological instability.
