1. Dysplasia of uterus: Dysplasia of uterus is easy to be combined with abnormal blood supply, resulting in uterine ischemia and hypoxia and dysmenorrhea.
2. Excessive uterine contraction: Although the uterine contraction pressure of patients with dysmenorrhea is basically the same as that of normal women, the duration of uterine contraction is long and it is often difficult to completely relax, so dysmenorrhea caused by excessive uterine contraction occurs.
3. Endocrine factors: Menstrual abdominal pain is related to the increase of progesterone in luteal phase.
4. Abnormal uterine position: If the position of a woman's uterus is extremely backward or forward, it can affect the smoothness of menstrual blood and cause dysmenorrhea.
5, cervical canal stenosis: mainly due to the obstruction of menstrual outflow, causing dysmenorrhea.
6. Abnormal uterine contraction: Patients with dysmenorrhea often have abnormal uterine contraction, which often leads to uterine smooth muscle ischemia, which in turn can cause spasmodic contraction of uterine muscles, resulting in pain and dysmenorrhea.
7. Gynecological diseases, such as endometriosis, pelvic inflammatory disease, adenomyosis and hysteromyoma. Placement of intrauterine devices can also easily cause dysmenorrhea.
8. Mental and neurological factors: Some women are too sensitive to pain.
9. Girls have menarche, and they are under great psychological pressure. Sitting for a long time leads to poor blood circulation, poor menstrual flow, and they like to eat cold drinks and pears and other raw and cold foods to cause dysmenorrhea.
1, strenuous exercise during menstruation, cold or too little clothing and cold lead to stagnation of qi and blood, which are easy to cause dysmenorrhea.
The above are the general reasons for dysmenorrhea, but which kind do you belong to? You won't know until you have a detailed examination in the hospital. Dysmenorrhea still has a great influence on women, so you must actively treat it to avoid causing more harm.
