This has a great connection with our physical condition. Dysmenorrhea can be divided into primary dysmenorrhea and secondary dysmenorrhea.

Dysmenorrhea is sometimes closely related to mental factors. It may also be due to spasmodic contraction of uterine muscles, which leads to uterine ischemia and dysmenorrhea. More common in uterine dysplasia, cervical stenosis or cervical canal, excessive uterine flexion, so that menstrual blood flow is not smooth, resulting in menstrual blood retention, thus stimulating uterine contraction and causing dysmenorrhea.

Primary dysmenorrhea can be relieved after childbirth. There are many factors that cause dysmenorrhea, and the common ones are as follows:

1, cervical canal stenosis

The main reason is that menstrual outflow is blocked, causing dysmenorrhea.

2. Uterine dysplasia

Poor uterine development is easy to be complicated with abnormal blood supply, resulting in uterine ischemia and hypoxia and dysmenorrhea.

3. 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.

4. Mental and neurological factors

Some women are too sensitive to pain.

5. Genetic factors.

6. Endocrine factors

Menstrual abdominal pain is related to the increase of progesterone in luteal phase.

7. The content of prostaglandin (PG) in endometrium and menstrual blood increased.

Prostaglandin E2(PGE2) can act on uterine muscle fibers to contract and cause dysmenorrhea. The content of prostaglandin in endometrial tissue of dysmenorrhea patients was significantly higher than that of normal women.

8, excessive contraction of the uterus

Although the uterine contraction pressure of patients with dysmenorrhea is basically the same as that of normal women (the normal pressure is about 4.9Kpa), the duration of uterine contraction is long and it is often difficult to completely relax, so dysmenorrhea caused by excessive uterine contraction occurs.

9. Abnormal uterine contraction

Dysmenorrhea patients often have abnormal uterine contraction, which often leads to uterine smooth muscle ischemia, which in turn can cause spasmodic contraction of uterine muscles, thus causing pain and dysmenorrhea.

10, gynecological diseases

Such as endometriosis, pelvic inflammatory disease, adenomyosis and hysteromyoma. Placement of intrauterine devices (IUDs) is also easy to cause dysmenorrhea.

1 1, menarche for girls

Psychological stress, sitting for a long time lead to poor blood circulation, poor menstrual flow, and love to eat cold drinks and foods, which lead to dysmenorrhea.

12, menstrual period

Violent exercise, being attacked by cold, dampness and cold, etc., are easy to cause dysmenorrhea.

13, external environment

The air is not easily stimulated by certain industrial or chemical odors, such as gasoline and banana oil, which cause dysmenorrhea.
