Menstruation is always prolonged, why is the menstrual period prolonged?

The pathogenesis of long menstrual cycle is both virtual and real, the empirical evidence is mostly due to blood stasis blocking, and new blood is not allowed to return to menstruation, and the false evidence is mostly due to yin deficiency and internal heat, disturbing the sea of blood, resulting in a long menstrual cycle. And understanding the virtual and real reasons for long menstrual cycles is also very helpful to figure out what to do if the menstrual cycle is too long.

1. Qi stagnation and blood stasis: If women are usually depressed, it will cause qi stagnation and blood stasis after a long time. Or women feel cold evil during menstruation and after childbirth, and the cold evil hinders the flow of qi and blood and forms blood stasis. Due to blood stasis blocking the cell veins, new blood cannot return to menstruation, resulting in continuous delay in menstrual bleeding.

2. Yin deficiency and internal heat: If a woman has a yin deficiency constitution, or due to a long-term illness, the yin fluid is consumed, the production is excessive, and the yin blood in the body is depleted. Yin deficiency and internal heat cause the blood to be restless, and the menstrual blood cannot function normally, resulting in a long menstrual cycle.

The length of the menstrual cycle varies greatly from person to person, not only is it different for every woman, but it is not always the same for the same woman. Factors such as environment, climate change, mental stress, childbirth, etc., can change the menstrual cycle.

A prolonged menstrual cycle is defined as a cycle of more than 40 days or longer. The length of the cycle may be regular, or the length of each cycle may be variable, and the menstrual period and flow are generally normal. Some of the prolonged cycles are mainly due to the prolongation of the follicular phase, while the luteal phase generally remains for 14-15 days, that is, only the menstrual cycle is prolonged, but the ovulation function of the ovaries is still normal, but the frequency of menstruation is rarer than normal.

However, it has been reported that patients with oligomenorrhea have no cyclical ovulation and a higher proportion of luteal insufficiency than those with normal menstrual cycles. The more irregular or longer the menstrual cycle, the higher the proportion of these possible points, and progressive prolongation of the menstrual cycle is often a precursor to amenorrhea.

Under normal circumstances, a woman's menstrual period lasts 3-7 days, and if it lasts longer than 7 days, it is a prolonged period. Prolonged menstruation should be taken seriously, and it should be searched for so that appropriate measures can be taken. Common conditions that cause prolonged menstrual periods are as follows:

Blood diseases such as thrombocytopenic purpura, aplastic anemia, etc., are often accompanied by menstrual cramps, and if there is severe uterine bleeding, menstrual prolongation occurs. Others, such as chronic anemia, chronic hepatitis, liver cirrhosis, nephritis, etc., can make the blood vessel wall fragile and increase permeability and cause bleeding. This condition requires a primary disease.

Pelvic inflammation, endometrial polyps, endometritis, etc. are all caused by poor endometrial blood circulation, degeneration and necrosis, or pelvic congestion, which cause heavy menstrual bleeding and prolonged menstruation. Once the above situation is discovered, it needs to be timely**.

Chronic uterine hypertrophy (myositis) is caused by pelvic congestion and a continuous increase in ovarian estrogen, which thickens the myometrium, causing heavy menstrual bleeding and prolonged menstruation.

Uterine fibroids, especially submucosal fibroids of the uterus, can cause heavy menstrual bleeding and prolonged menstruation due to abnormal contraction due to the enlargement of the uterine cavity.

Uterine dysfunctional bleeding, such as anovulatory dysfunctional uterine bleeding and irregular endometrial shedding, are caused by endocrine dysfunction and prolonged menstruation.

Endometriosis.

Heavy menstrual bleeding or prolonged menstruation are often caused by affecting myometrial contraction or endometrial enhancement.

In addition, IUD insertion can also cause prolonged periods. In this case, you can take traditional Chinese medicine for conditioning, and if the effect is not satisfactory, you can consider changing the contraceptive method.
