How is pregnancy abnormal enlargement?

Abnormal enlargement of the uterus during pregnancy can be caused by multiple pregnancies, polyhydramnios, uterine fibroids, adenomyosis, uterine abnormalities, and other conditions. There are many causes of abnormal enlargement of the uterus during pregnancy, but the following are some common causes: 1. Multiple pregnancy: In multiple pregnancies, the uterus is larger than in single pregnancies. 2. Polyhydramnios: When there is too much amniotic fluid, the uterus will be enlarged by amniotic fluid. 3. Uterine fibroids: Uterine fibroids are benign tumors formed by proliferation of uterine smooth muscle cells, which may lead to uterine enlargement. 4. Adenomyosis: This is a diffuse or localized lesion formed by invasion of endometrial glands and stroma into the myometrium, which also causes uterine enlargement. 5. Uterine abnormalities: Such as double uterus, septate uterus, etc., may also lead to abnormal uterine enlargement. 6. Other: such as hydatidiform mole, choriocarcinoma and other diseases, may also cause uterine enlargement. If abnormal uterine enlargement is found during pregnancy, it is necessary to seek medical attention in time for detailed examination and diagnosis to determine the specific cause and take corresponding treatment measures.
