What is the reason for prolonged absence of menstruation?

Many people do not have their menstruation for a long time. In this case, many people will judge it as amenorrhea. In fact, if the menstruation is not here for a long time, you may face the risk of amenorrhea. You must check as soon as possible to rule out some possible factors. The long absence of menstruation mainly includes the endometrium, or because the placement of an IUD affects the circulation of the endometrium. In addition, it includes functional bleeding of the uterus and chronic cervical hypertrophy, which will cause the patient's menstruation to be irregular for a long time.

1. Endometriosis: The occurrence of endometriosis will affect the contraction of the uterine muscle layer or the enhancement of the endometrium. The enhancement of the endometrium will lead to a prolonged endometrial shedding time, resulting in excessive menstrual cycles or prolonged menstruation.

2. Placement of an IUD: When an IUD is placed, the endometrium is compressed by the ring, causing inflammatory infiltration of cells, which can easily lead to prolonged menstruation.

3. Uterine leiomyoma: especially submucosal uterine leiomyoma. This is because the area of ​​the uterine cavity is enlarged, leading to abnormal uterine contraction, which may cause excessive menstrual cycles and prolonged menstruation.

4. Dysfunctional uterine bleeding: such as anovulatory dysfunctional uterine bleeding and irregular endometrial shedding, are both caused by endocrine dysfunction, which leads to a longer menstrual cycle.

5. Chronic uterine hypertrophy: Due to pelvic congestion, ovarian estrogen continues to increase, causing the uterine muscle layer to thicken, forming chronic uterine hypertrophy, causing excessive menstrual cycles and prolonged menstruation.

6. Blood diseases: such as thrombocytopenic purpura, aplastic anemia, etc., are often accompanied by menstrual cycles. If severe uterine bleeding occurs, the menstrual period will be prolonged. Other conditions such as chronic anemia, chronic hepatitis, cirrhosis, nephritis, etc. can make the blood vessel walls fragile, increase permeability and cause bleeding.

7. Others: Pelvic inflammation, intrauterine polyps, uterine inflammation, etc. are all caused by poor intrauterine blood circulation, degeneration and necrosis, or pelvic congestion, which lead to excessive menstrual cycles and prolonged menstruation.
