Dysmenorrhea may be caused by genital tract malformations

Dysmenorrhea may be caused by reproductive tract malformations, and of course it may also be caused by other factors. Do you know what the common causes of dysmenorrhea are? This is a question that people ask a lot. Let the experts explain it to you in detail.

The main causes of dysmenorrhea are as follows:

1. Reproductive tract malformation: During embryonic development, the paramesonephric duct on one side can develop well, forming a well-developed unicornuate uterus. However, the paramesonephric duct on the other side 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, it manifests as periodic bleeding, which can cause dysmenorrhea due to blood accumulation in the uterine cavity. Most patients are young girls, and this 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. Patients often have menorrhagia, prolonged menstruation or irregular vaginal bleeding. Pelvic examination can reveal varying degrees of enlargement of the uterus, with a smooth surface or nodular protrusions. The cause of secondary dysmenorrhea caused by this disease is not common.

3. Adenomyosis: The cause of secondary dysmenorrhea is 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 menstrual period. Gynecological examination shows that the uterus is uniformly enlarged and spherical, with a hard texture, generally about the size of a 2-month pregnancy, and there may be mild tenderness.

4. Intrauterine contraceptive device: Dysmenorrhea can also be seen in women who have an intrauterine contraceptive device placed. This type of dysmenorrhea may be caused by an increase in prostaglandins produced by the endometrium, or it may be that the contraceptive device stimulates the rejection contraction of the uterine muscles, leading to spasmodic pain in the lower abdomen. Patients often have discomfort in the lower abdomen or lumbar region, and their menstrual symptoms are aggravated, which manifests as dysmenorrhea. Improper placement of the IUD or an oversized IUD can also easily cause uterine contractions, leading to lower abdominal pain and dysmenorrhea.

The above is the explanation given by experts on the causes of dysmenorrhea, I hope it can help you answer your questions. What the experts want to tell you is that in daily life, we must pay attention to our living habits and not cause diseases because of our bad habits.
