What is the cause of dysmenorrhea in women?

Experts at the hospital pointed out that there are many causes of dysmenorrhea in women, with organic diseases being the most common, such as adenomyosis, excessive uterine curvature, intrauterine adhesions, pelvic adhesions, endometrial polyps, submucosal fibroids, cervical stenosis, uterine malformations, intrauterine contraceptive devices, hymen occlusion, etc., all of which can cause dysmenorrhea to varying degrees.

The common causes of dysmenorrhea in women are as follows:

(1) Cervical stenosis is mainly caused by obstruction of menstrual outflow, which causes dysmenorrhea.

(2) Uterine hypoplasia Poor uterine development is prone to abnormal blood supply, causing uterine ischemia and hypoxia, leading to dysmenorrhea.

(3) Abnormal uterine position: If a woman’s uterus is extremely retroflexed or anteflexed, it may affect the smooth flow of menstrual blood and cause dysmenorrhea.

(4) Psychological and neurological factors: Some women are overly sensitive to pain.

(5) Genetic factors: Dysmenorrhea in daughters is related to dysmenorrhea in mothers.

(6) Endocrine factors: Abdominal pain during menstruation is related to increased progesterone in the luteal phase.

(7) Dysmenorrhea caused by menarche, psychological stress, long periods of sitting leading to poor blood circulation, poor menstrual blood flow, and a preference for cold foods

(8) The level of prostaglandins (PG) in the endometrium and menstrual blood increases. Prostaglandin E2 (PGE2) acts on uterine muscle fibers to cause them to contract and cause dysmenorrhea. The level of prostaglandins in the endometrial tissue of menstrual patients is significantly higher than that of normal women.

(9) Although the uterine contraction pressure of patients with dysmenorrhea is basically the same as that of normal women (normal pressure is about 4.9Kpa), the uterine contraction lasts longer and is often difficult to relax completely, so dysmenorrhea occurs due to excessive uterine contraction.

(10) Abnormal contraction. Patients with dysmenorrhea often experience abnormal uterine contraction, which often leads to ischemia of the uterine smooth muscle. Uterine muscle ischemia can cause spasmodic contraction of the uterine muscle, resulting in pain and dysmenorrhea.

(11) Medical diseases such as endometriosis, pelvic inflammatory disease, adenomyosis, uterine fibroids, etc. The placement of an intrauterine device (commonly known as an IUD) in the uterus can also easily cause dysmenorrhea.

(12) Vigorous exercise during menstruation, exposure to wind, cold, dampness, etc. can easily cause dysmenorrhea, which is also one of the causes of dysmenorrhea in women.

(13) Bad air quality and the irritation of certain industrial or chemical odors can cause dysmenorrhea.
