What causes prolonged menstruation?

Many women do not have a deep understanding of menstruation and think that it is okay if the menstrual period lasts for a long time. In fact, the reasons for prolonged menstruation are multifaceted and complex, including genetic problems, endocrine problems, mental factors, systemic diseases, etc. So what are the common causes of prolonged menstruation?

1. Uterine dysfunction

Dysfunctional uterine bleeding is one of the reasons for prolonged menstruation in women. For example, anovulatory dysfunctional uterine bleeding and irregular endometrial shedding are both caused by endocrine dysfunction, which leads to prolonged menstruation.

2. Pelvic inflammatory disease and endometritis

Pelvic inflammatory disease or endometritis can cause women to have problems such as poor endometrial blood circulation, degeneration and necrosis, or pelvic congestion, which may lead to prolonged menstruation.

3. Uterine fibroids

Uterine fibroids in women, especially submucosal fibroids, can cause the area of ​​the uterus to increase and cause abnormal contraction, which may lead to prolonged menstruation.

4. Endometriosis

Endometriosis may also affect the contraction of the uterine muscle layer or cause the endometrium to strengthen, which may cause patients to have prolonged menstrual periods.

5. Blood diseases

For example, thrombocytopenic purpura, aplastic anemia, etc., cause women to have prolonged menstruation due to coagulation disorders during menstruation.

6. Systemic diseases

Systemic diseases such as chronic anemia, chronic hepatitis, cirrhosis, nephritis, etc. can cause women to have problems such as fragile uterine walls and increased permeability, which can lead to prolonged menstruation.
