Dysmenorrhea is one of the common symptoms of women, which generally refers to abdominal pain before and after menstruation or menstrual period, accompanied by back pain or other discomfort. Dysmenorrhea seriously affects women's lives. Dysmenorrhea can generally be divided into two categories: primary dysmenorrhea and secondary dysmenorrhea. There are many reasons for dysmenorrhea, such as uterine dysplasia.

What are the causes of dysmenorrhea?

1. Cervical canal stenosis hinders menstrual outflow, leading to dysmenorrhea.

2. Female uterine dysplasia or dysplasia is prone to abnormal blood supply, leading to dysmenorrhea caused by uterine ischemia or hypoxia.

3. Abnormal position of female uterus. If the position of the female uterus bends forward or backward, it will affect the poor blood flow and lead to dysmenorrhea.

4. Some neurological factors, or mental reasons, cause women to be too sensitive to pain, so dysmenorrhea will occur.

5. Because of genetic reasons, the mother has dysmenorrhea, and the daughter usually has dysmenorrhea.

6. Endocrine reasons, menstrual abdominal pain is generally related to endocrine disorders.

7. The content of prostaglandin in female endometrium and menstrual blood is too high, and prostaglandin acts on the muscle fibers of uterus and contracts, so dysmenorrhea occurs.

8. Excessive uterine contraction in women. Although the uterine contraction pressure of dysmenorrhea women is similar to that of normal women, the uterine contraction time of dysmenorrhea women is too long, which is easy to relax completely, leading to dysmenorrhea.

9. Abnormal uterine contraction. Women with dysmenorrhea often contract abnormally, which often leads to uterine smooth muscle ischemia, which can cause uterine spasm, thus causing pain and dysmenorrhea.

10. Some gynecological diseases, such as endometriosis, pelvic inflammatory disease and hysteromyoma, can cause dysmenorrhea.
