Dysmenorrhea is the most obvious symptom of adenomyosis. It can be said that every menstruation is excruciatingly painful. But why does this disease cause dysmenorrhea? This question of course depends on its onset. Let’s ask Director Xie Junmin of Zhengzhou Huashan Hospital to explain it to you.
Why does adenomyosis cause dysmenorrhea?
Director Xie Junmin said: Adenomyosis is the dislocation of normal endometriosis into the myometrium, forming hyperplasia and edema during the menstrual period. , bleeding and other symptoms are the main causes of dysmenorrhea. After the ectopic endometrium infiltrates into the myometrium, it can cause bleeding and fall off in the myometrium during each menstruation. The myometrium of the uterus has a dense structure. Extensive bleeding of ectopic endometrium in the myometrium increases the tension of the myometrium and causes spasmodic contraction of uterine smooth muscle, which can cause dysmenorrhea.
The reason why the lesions are mostly concentrated in the fundus and posterior wall of the uterus:
The ectopic endometrial tissue periodically moves and invades and reproduces every month, making the symptoms of dysmenorrhea worse every month. , the myometrium of the uterus is significantly thickened, and the uterus is getting larger and larger. When women rest in bed during dysmenorrhea, the retained menstrual blood cannot be discharged for a long time. Due to gravity, the ectopic endometrial tissue easily invades the fundus and posterior wall of the uterus, forming endometriosis in these two parts. There are many cases, and the majority of endometriosis is formed on the anterior wall of the uterus after caesarean section.
Does the degree of dysmenorrhea increase as the disease worsens?
Regarding this point, Director Xie said: The degree of dysmenorrhea in patients with adenomyosis will worsen as the condition worsens. Because the endometrium sheds every month, but the endometrium in the myometrium cannot be excreted, and over time, the lesions gradually become larger. The condition is getting more and more serious. The pain is unbearable and I can't sleep at night. You need to take strong painkillers to get relief. During every menstrual period, patients' physical pain and psychological fear are similar to those of cancer. This is one of the reasons why the disease is called a "benign cancer."
