Uterine fibroids found after pregnancy do not need to be treated and regular observation is sufficient. Smaller and asymptomatic fibroids do not pose much threat to pregnancy for the time being and can be left untreated. In the early stages of pregnancy, when the fetus is not very stable, medication will be detrimental to the fetus, and surgical treatment may cause miscarriage. In the middle and late stages of pregnancy, the blood flow in the uterus becomes richer and richer, and if a myomectomy is done it will increase the amount of bleeding and there will be difficulties in stopping the bleeding. If an unforeseen situation occurs, such as a fibroid that causes uterine contractions during pregnancy, medication to inhibit uterine contractions and plenty of rest may be given. If red degeneration of the fibroid occurs, anti-inflammatory drugs can be used to reduce the inflammation, and then drugs to inhibit contractions can be used to settle the pregnancy, all of which can smooth out the pregnancy.
