Uterine fibroids are the most common benign tumors of the female reproductive system, commonly seen in women between the ages of 30 and 50, and rarely under the age of 20. Most are not serious, and the specifics are related to the size, location, and presence or absence of symptoms of fibroids. The uterine wall is divided into plasma layer, myometrium and mucosa layer from outside to inside, and fibroids are classified into subplasma fibroids, interstitial fibroids and submucosal fibroids according to the relationship between fibroids and the muscle wall. Subplasmalemmal fibroids tend to grow toward the surface of the uterus and have little effect on the morphology and function of the uterine cavity. Most patients have no symptoms, are not serious, and have little effect on menstruation and pregnancy. Some of the larger interstitial myomas and submucosal myomas increase the size of the uterine cavity and increase the endometrial area, and the larger myomas affect the contraction of the uterus, which may affect menstruation and pregnancy, such as excessive menstruation, prolonged menstruation, and in severe cases, anemia; pregnant patients may have increased risk of miscarriage, abnormal fetal position, placental hypoplasia, placenta previa, obstructed obstructed labor, and postpartum hemorrhage, etc. Some women may have severe abdominal pain Some women may experience severe abdominal pain with nausea, vomiting, and fever. Fibroids growing in the uterine horns on both sides of the uterus can cause infertility. Therefore, fibroids that are small or asymptomatic or have mild symptoms are not serious and can be treated without regular review. Larger fibroids or those in special locations can affect menstruation and pregnancy and can be treated with medication or surgery. It is recommended that women have a preconception checkup when preparing for pregnancy, and if the checkup reveals fibroids that need treatment, they should be treated early.
