Why do women experience dysmenorrhea during their menstrual period?

In clinical medical research, dysmenorrhea is a menstrual disease characterized by periodic abdominal pain, pain in the lumbar region, and even severe pain and fainting during and before and after menstruation. I believe that although most women experience dysmenorrhea, their understanding of the causes of dysmenorrhea is still limited.

1. The cause of dysmenorrhea is the increase of prostaglandin (PG) content in the endometrium and menstrual blood. Prostaglandin E2 (PGE2) acts on uterine muscle fibers to cause contraction, which causes dysmenorrhea. The prostaglandin content in the endometrial tissue of patients with dysmenorrhea is significantly higher than that of normal women. Excessive contraction of the uterus. Although the uterine contraction pressure of patients with dysmenorrhea is basically the same as that of normal women. However, the duration of uterine contraction is longer, and it is often difficult to relax completely, so dysmenorrhea caused by excessive uterine contraction occurs. The cause of dysmenorrhea is abnormal uterine contraction. Patients with dysmenorrhea often have abnormal uterine contraction, which often leads to ischemia of uterine smooth muscle. The ischemia of uterine muscle can cause spasmodic contraction of uterine muscle, resulting in pain and dysmenorrhea.

2. Cervical stenosis is mainly caused by obstruction of menstrual outflow, which causes dysmenorrhea. The cause of dysmenorrhea is uterine hypoplasia. Poor uterine development is prone to abnormal blood supply, causing uterine ischemia and hypoxia, which causes dysmenorrhea. Abnormal uterine position If a woman's uterus is extremely retroflexed or anteflexed, it can affect the smooth flow of menstrual blood and cause dysmenorrhea.

3. Mental and neurological factors: Some women are overly sensitive to pain. Genetic factors: Dysmenorrhea in daughters is related to dysmenorrhea in mothers. Endocrine factors: Abdominal pain during menstruation is related to the increase of progesterone in the luteal phase.

4. Gynecological diseases such as endometriosis, pelvic inflammatory disease, adenomyosis, uterine fibroids, etc. The cause of dysmenorrhea is the placement of an intrauterine device (commonly known as an IUD) in the uterus, which can also easily cause dysmenorrhea. Dysmenorrhea is caused by the first menstruation of girls, psychological pressure, long-term sitting leading to poor blood circulation, poor menstrual blood flow, and a preference for cold foods. Vigorous exercise during menstruation, cold wind and dampness, etc., are all likely to cause dysmenorrhea.

The above factors are all the causes of dysmenorrhea. I hope it can help you better understand the knowledge of dysmenorrhea. I also hope that friends with dysmenorrhea can go to the hospital for treatment in time. If you have other dysmenorrhea questions, you can contact our online experts to answer your questions.
