What causes prolonged menstrual cycle?

When menstruation occurs in women, it will accompany them for decades. Generally, women's menstruation is very regular, but sometimes abnormal situations may occur, the most typical of which are early menstruation and prolonged menstruation, and women are very concerned about the causes. So, what is the reason for the prolonged menstrual cycle? Let’s take a closer look at it below.

Blood diseases: such as thrombocytopenic purpura, aplastic anemia, etc., are often accompanied by menstruation. 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.

Pelvic inflammation, intrauterine polyps, endometritis, etc. are all caused by poor intrauterine blood circulation, degeneration and necrosis, or pelvic congestion, which lead to excessive menstruation and prolonged menstruation.

Chronic uterine hypertrophy (myometritis): Due to pelvic congestion, ovarian estrogen continues to increase, causing thickening of the uterine muscle layer, resulting in excessive menstruation and prolonged menstruation.

Uterine fibroids: especially submucosal uterine fibroids, due to the expansion of the uterine cavity area and abnormal contraction, it can cause menorrhagia and prolonged menstruation.

Dysfunctional uterine bleeding: such as anovulatory dysfunctional uterine bleeding and irregular endometrial shedding, both of which cause prolonged menstruation due to endocrine dysfunction.

Endometriosis: often causes menorrhagia or prolonged menstruation due to affecting the contraction of the uterine muscle layer or due to enhancement of the endometrium.

The above is an introduction to the reasons for prolonged menstrual cycle. I hope it will be helpful for women to understand. Women's menstrual period is generally fixed. When it is prolonged, it must be taken seriously. It is best to go to a regular hospital for diagnosis, then find the cause and actively treat it to avoid causing greater impact on women's health.
