There are many factors that lead to dysmenorrhea.

I think women should be familiar with dysmenorrhea. Most women should have experienced dysmenorrhea. The occurrence of dysmenorrhea is caused by many factors, and many women do not know what factors cause dysmenorrhea . Let's take a look at the main factors that cause dysmenorrhea.

When a girl has her first menstruation, psychological stress, long periods of sitting leading to poor blood circulation, poor menstrual blood flow, and a preference for cold foods can cause dysmenorrhea.

The content of prostaglandins (PG) in the endometrium and menstrual blood increases. Prostaglandin E2 (PGE2) acts on the uterine muscle fibers to contract and cause dysmenorrhea. The content of prostaglandins in the endometrial tissue of patients with menstruation is significantly higher than that of normal women.

Excessive uterine contraction can also easily lead to dysmenorrhea. Although the uterine contraction pressure of dysmenorrhea patients is basically the same as that of normal women (normal pressure is about 4.9Kpa), the uterine contraction lasts longer and is often difficult to completely relax, so dysmenorrhea caused by excessive uterine contraction occurs.

The cause of dysmenorrhea is also related to abnormal uterine contraction. Patients with dysmenorrhea often have abnormal uterine contraction, which often leads to ischemia of uterine smooth muscle. Uterine muscle ischemia can cause spasmodic contraction of uterine muscle, thus causing pain and dysmenorrhea.

The causes of dysmenorrhea are caused by the above factors. In addition to these external factors, there are some other factors. Women who want to know more about the causes of dysmenorrhea can consult relevant professional doctors, who will introduce you to more dysmenorrhea-related knowledge in detail. I hope the introduction of the above knowledge can be helpful to women.
