What causes secondary dysmenorrhea in women?

Dysmenorrhea is generally more common in primary dysmenorrhea, and less common in secondary dysmenorrhea. Secondary dysmenorrhea seriously affects women's lives. So what are the causes of secondary dysmenorrhea ? The following is a detailed answer from relevant experts.

① Endometriosis: It is a common cause of secondary dysmenorrhea, which is more common in middle-aged women aged 30 to 45. It is caused by the endometrium running outside the uterus and "setting up camp". It is affected by ovarian hormones and thickens and bleeds. Since it does not flow out of the body, it stimulates the surrounding tissues, causing uterine muscle contraction or tissue fibrosis, which induces dysmenorrhea.

② Uterine adenomyoma: It is more common in women over 40 years old, multiparous women, women who have had multiple abortions and curettages, and is also a common cause of secondary dysmenorrhea

③ Cervical or uterine cavity adhesions: more common in patients with repeated abortions, endometrial tuberculosis, etc.

④ Reproductive tract malformation: mechanical obstruction such as excessive anteversion of the uterus and vaginal septum, which makes menstrual blood flow poorly and causes blood accumulation and induces secondary dysmenorrhea

The above is an introduction to the causes of secondary dysmenorrhea. I believe everyone should have a certain understanding of dysmenorrhea. If you want to know more about dysmenorrhea, please consult online experts.
