A cesarean section for a combined pregnancy with fibroids is different from a simple cesarean section. In the former case, the fibroids between the muscle walls are treated accordingly. During cesarean delivery, it is necessary to ensure the health and safety of the baby, so a transverse incision is usually made in the lower part of the uterus to safely deliver the fetus. At this time, the pelvic cavity is in a state of congestion and the uterus, although previously small, becomes larger as it enters late pregnancy. There will be more bleeding during the excision of the fibroids. If it is not necessary, i.e. the fibroids are already large or have degenerative changes, they should not be excised during the cesarean section, which can lead to excessive bleeding. During the course of pregnancy, a woman’s body hormone levels are high, so fibroids may increase in size. When the pregnancy process is over, the hormone level in the body decreases and the fibroids will decrease, so it is not necessary to have fibroid surgery during the delivery process.
