Why do uterine fibroids grow larger during pregnancy? Will uterine fibroids grow quickly during pregnancy?

During pregnancy, some women may find that they have uterine fibroids. Uterine fibroids are a common gynecological disease. They are benign tumors composed of endometrial tissue. However, some women may find that the size of their uterine fibroids seems to grow rapidly during pregnancy. So why do uterine fibroids grow larger during pregnancy? Do uterine fibroids grow quickly during pregnancy?

Let's take a look at the relationship between uterine fibroids and pregnancy. Uterine fibroids are formed by the proliferation of smooth muscle cells in the uterine wall. This muscular tumor can grow in different locations within the uterine wall, sometimes attached to the uterine cavity, called intracavitary fibroids. During pregnancy, the uterine wall expands due to the growth of the fetus in the uterus, which can also cause existing uterine fibroids to enlarge. The increase in hormone levels such as estrogen and progesterone during pregnancy may also provide conditions for the growth of uterine fibroids.

Whether or not uterine fibroids grow quickly during pregnancy depends on individual circumstances. Some women may find that their uterine fibroids grow rapidly, while others may notice that their fibroids grow relatively slowly. This is closely related to factors such as the location, size, and type of uterine fibroids. Generally speaking, fibroids within the uterine cavity may grow faster during pregnancy, while fibroids growing within the uterine wall may grow relatively slowly.

One reason uterine fibroids may increase in size is due to the increased blood supply to the pelvis. During pregnancy, the blood supply around the uterus increases to meet the needs of the growing fetus. This also increases the blood supply to the fibroids, which can promote their growth. Progesterone production increases during pregnancy, and progesterone can promote the growth of uterine fibroids. Therefore, the increase in size of uterine fibroids during pregnancy may also be related to the effects of estrogen and progesterone.

So, can uterine fibroids during pregnancy affect the fetus or pregnant women? In most cases, uterine fibroids will not have much impact on the fetus or pregnant women. However, for those larger or more numerous uterine fibroids, complications such as placental abruption, threatened abortion or premature birth may occur. Therefore, if you are found to have uterine fibroids during pregnancy, it is recommended to seek medical attention in time and receive professional consultation and monitoring.

Uterine fibroids grow larger during pregnancy mainly because of factors such as the expansion of the uterine wall and increased blood supply. Although the growth rate of uterine fibroids during pregnancy varies from person to person, in most cases the impact on the fetus and pregnant woman is small. However, for larger or more numerous fibroids, some complications may occur. Therefore, if fibroids are found during pregnancy, you should seek medical attention in time and monitor and treat them according to the doctor's advice.
