Why do uterine fibroids grow during pregnancy? The reason why uterine fibroids grow rapidly after pregnancy

Uterine fibroids are a common benign tumor in the female reproductive system. Especially during pregnancy, uterine fibroids tend to grow larger. So why do uterine fibroids grow larger during pregnancy, and why do they grow rapidly after pregnancy?

Why do uterine fibroids grow during pregnancy? It is mainly due to changes in hormone levels. During pregnancy, the levels of estrogen and progesterone in women's bodies increase significantly, which promotes the proliferation of the endometrium and the growth of uterine fibroids. Estrogen is an important hormone that promotes the proliferation of endometrial glands, while progesterone helps maintain pregnancy and increase uterine blood flow. The increase of these two hormones provides favorable conditions for the growth of uterine fibroids, causing uterine fibroids to easily grow larger during pregnancy.

There are several reasons why uterine fibroids grow rapidly after pregnancy. During pregnancy, the uterus enlarges and the blood supply increases, which provides more nutrients for the growth of uterine fibroids. The effect of progesterone also increases the blood flow to uterine fibroids, which is more conducive to their growth. During pregnancy, the pressure around uterine fibroids increases, which also stimulates their continued growth. These reasons work together to cause uterine fibroids to grow rapidly after pregnancy.

So, does the growth of uterine fibroids have an impact on pregnant women? In most cases, the growth of uterine fibroids will not cause much harm to pregnant women and fetuses. Pregnant women should have regular prenatal examinations during pregnancy, and doctors can assess whether treatment is needed based on the size and location of the uterine fibroids. Generally, surgery is only necessary when the uterine fibroids are too large, located in the cervix, or accompanied by abnormal malignant changes.

However, if a woman has discovered that she has uterine fibroids when planning a pregnancy, it is best to receive treatment before pregnancy. Because pregnancy will increase the growth rate of uterine fibroids and increase the risk of complications. Uterine fibroids that are too large may lead to abnormal placental implantation and restricted fetal development. At the same time, uterine fibroids may also affect the contraction of the uterus and increase the possibility of difficult delivery. Therefore, for women who have discovered uterine fibroids before pregnancy, it is best to consult a doctor before pregnancy to decide whether surgical removal is needed.

The main reason why uterine fibroids tend to grow larger during pregnancy is the change in hormone levels, while the rapid growth of uterine fibroids after pregnancy is due to the increase in estrogen and progesterone, endometrial hyperplasia, and increased uterine blood flow. For women with uterine fibroids during pregnancy, they should receive regular prenatal examinations and receive treatment according to the doctor's advice. At the same time, women who have discovered uterine fibroids before planning pregnancy should consult a doctor in time to develop a suitable treatment plan. This is the only way to ensure the health of mother and baby.
