Let's analyze the causes of primary dysmenorrhea for you

Dysmenorrhea is common during menstruation. Dysmenorrhea is divided into many types, and primary dysmenorrhea is one of them. It is important to understand the causes of primary dysmenorrhea in a timely manner. Let's learn about it from the following article.

1. Prostaglandins are one of the causes of primary dysmenorrhea. Studies have found that patients with dysmenorrhea have increased uterine cavity pressure, increased contraction frequency, uncoordinated contractions and rhythm disorders, which lead to reduced uterine blood flow and hypoxia, causing severe pain in patients. When dysmenorrhea patients are given intravenous injections of stimulants, uterine contractions disappear, local blood flow improves significantly, and pain is completely relieved.

2. Primary dysmenorrhea often occurs in the menstrual cycle with ovulation, indicating that primary dysmenorrhea is related to the release of autologous hormones after ovulation. The content of PGs in the endometrium also changes periodically. Adolescent girls do not ovulate and have no dysmenorrhea, and the PCs content at that time is only 1/5 of the ovulation cycle; after taking oral contraceptives, the amount of PGs in menstrual blood drops below the normal level, indicating that the imbalance of ovarian hormones can affect the synthesis of D in the endometrium and cause primary dysmenorrhea. Therefore, this is also the main factor that induces primary dysmenorrhea.
