There are many girls who experience dysmenorrhea during menstruation, but not everyone will suffer from dysmenorrhea. What are the causes of dysmenorrhea ? Let's learn more about dysmenorrhea from the following article. 1. Reproductive tract malformation: During embryonic development, one side of the mesonephric duct can develop well, forming a well-developed unicornuate uterus. However, the other side of the mesonephric duct develops poorly, forming a rudimentary horn or primordial uterus, which is not connected to the opposite side and does not lead to the body. The primordial uterus generally has no uterine cavity, or has a uterine cavity but lacks endometrium; if the primordial uterus has functional reactions, manifested as periodic bleeding, dysmenorrhea may be caused by blood accumulation in the uterine cavity. Most patients with dysmenorrhea are young girls, which is the cause of secondary dysmenorrhea. 2. Uterine fibroids: Dysmenorrhea is not the main symptom of uterine fibroids, but submucosal fibroids can cause spasmodic pain during menstruation due to stimulation of uterine contraction. Dysmenorrhea patients often have menorrhagia, prolonged menstruation or irregular vaginal bleeding. Pelvic examination can reveal varying degrees of enlargement of the uterus. The cause of secondary dysmenorrhea caused by this disease is not common. 3. Adenomyosis: Secondary dysmenorrhea is caused by a benign disease caused by the invasion of the endometrium into the uterine muscle layer. Dysmenorrhea is one of the typical symptoms of this disease. There may also be increased menstrual flow or prolonged menstruation. The article describes the causes of dysmenorrhea. I hope that after reading it, you will understand how dysmenorrhea is caused.
