Pregnancy after uterine fibroid surgery is more dangerous

Generally speaking, women with uterine fibroids can get pregnant if the fibroids are less than 4 cm in diameter. However, if the uterine fibroids grow to a diameter of more than 4 cm before pregnancy and grow during pregnancy, the chances of degeneration, miscarriage, and premature birth will increase; or if the fibroids are less than 4 cm in diameter but grow in a bad location, such as in the uterine cavity, on the cervix, or compress the fallopian tubes and affect infertility, it is best to have surgery to remove the fibroids before getting pregnant. People who have undergone traumatic surgeries such as myomectomy or cesarean section may have scars on their uterus, which is medically called a scarred uterus. Anyone with a scarred uterus must be cautious and careful during pregnancy and childbirth.

As we all know, after a woman becomes pregnant, her uterus gradually enlarges. When the fetus is full-term, it can even enlarge to 700 times its size before pregnancy. The uterine muscle fibers will also be stretched and stretched hundreds of times. When labor is about to begin, the uterus must rely on strong contractions to deliver the fetus. A normal uterus can handle these heavy tasks, but for a scarred uterus, the scarred tissue has reduced elasticity and toughness, increased fragility, and forms a relatively weak area in the uterus. If a woman becomes pregnant before the uterine wound has fully healed, as the fetus grows and develops in the uterus, the uterine scar may rupture due to excessive tension on the uterine wall, which will seriously endanger the safety of the mother and the fetus.

Therefore, it is recommended that women with uterine scars adhere to contraception and consider pregnancy 2 to 3 years after surgery. It is best to go to the hospital for a thorough examination to make sure that the body is in good condition and the scar has healed well before getting pregnant. During pregnancy, regular prenatal examinations should be conducted. If conditions permit, women can stay in the hospital two weeks before the expected date of delivery.

The delivery method for women with uterine scars depends on the specific situation. If the pregnant woman is in good physical condition, the scar heals well, the thickness is within the normal range, and the fetal position and birth canal are normal, natural delivery can be attempted, otherwise a cesarean section should be performed.
