There are many factors that cause dysmenorrhea, so it is necessary to find out the cause of dysmenorrhea and treat it symptomatically. Common ones are as follows:
First, cervical canal stenosis: mainly due to the obstruction of menstrual outflow, causing dysmenorrhea.
Second, uterine dysplasia: uterine dysplasia is easy to be complicated with abnormal blood supply, leading to uterine ischemia and dysmenorrhea.
3. Abnormal uterine position: If a woman's uterine position is extremely backward or forward, it can affect menstrual blood flow and cause dysmenorrhea.
Mental and neurological factors: Some women are too sensitive to pain.
5. Genetic factors.
Endocrine factors: Menstrual abdominal pain is related to the increase of progesterone in luteal phase.
Seven. The content of prostaglandin (PG) in endometrium and menstrual blood increased: Prostaglandin E2(PGE2) acted on uterine muscle fibers to make them contract, causing dysmenorrhea. The content of prostaglandin in endometrial tissue of dysmenorrhea patients was significantly higher than that of normal women.
Eight, excessive uterine contraction: although the uterine contraction pressure of dysmenorrhea patients is basically the same as that of normal women (the normal pressure is about 4.9Kpa), the uterine contraction lasts for a long time and it is often difficult to completely relax, so dysmenorrhea caused by excessive uterine contraction occurs.
Nine, abnormal uterine contraction: dysmenorrhea patients often have abnormal uterine contraction, which often leads to uterine smooth muscle ischemia. Uterine muscle ischemia can cause spasmodic contraction of uterine muscles, thus causing pain and dysmenorrhea.
X gynecological diseases: such as endometriosis, pelvic inflammatory disease, adenomyosis, hysteromyoma, etc. Placement of intrauterine devices is also easy to cause dysmenorrhea.
Eleven, menarche for girls: psychological stress, sedentary lead to poor blood circulation, poor menstrual flow, love to eat cold drinks and food and other causes dysmenorrhea.
Twelve, menstrual period: strenuous exercise, cold and dampness. It is easy to cause dysmenorrhea.
External environment: the air is not stimulated by certain industrial or chemical smells, such as gasoline and perfume, which causes dysmenorrhea.
