Under what circumstances will uterine fibroids not grow? What kind of uterine fibroids will continue to grow?

Uterine fibroids are a common tumor of the female reproductive system that usually grows in the wall of the uterus. Women of childbearing age may develop uterine fibroids, and they grow in a variety of ways. However, depending on individual differences and other factors, uterine fibroids sometimes stop growing and sometimes continue to grow. This article will discuss under what circumstances uterine fibroids will not grow and explore the reasons that cause them to continue to grow.

1. Uterine fibroids may no longer grow after menopause

The growth of uterine fibroids is directly related to ovarian function. The ovaries mainly secrete estrogen, which can promote the growth of uterine fibroids. Therefore, when women enter menopause, ovarian function gradually weakens, estrogen levels in the body decrease, and the driving force for the growth of uterine fibroids also weakens. Therefore, postmenopausal women often do not see uterine fibroids grow again.

2. The growth of uterine fibroids is often suppressed during pregnancy

During pregnancy, the level of androgen in women's bodies will increase significantly, and androgen has the effect of inhibiting the growth of uterine fibroids. The uterus will also undergo physiological enlargement during pregnancy, thereby limiting the space for uterine fibroids. Therefore, uterine fibroids often do not increase in size during pregnancy, and may even shrink.

3. Drug treatment may inhibit the growth of uterine fibroids

Drug therapy can also be used to inhibit the growth of uterine fibroids. For example, oral contraceptives can adjust the hormone balance in women's bodies, thereby slowing the growth of uterine fibroids. Hormonal drugs such as norepinephrine and recombinant human fetal antithrombin can also inhibit the growth of uterine fibroids by inhibiting the growth of new blood vessels.

However, why do uterine fibroids continue to grow?

1. The type of uterine fibroids is related to the growth rate

Uterine fibroids can be divided into different types, and their location and growth pattern can also lead to different growth rates. For example, uterine fibroids that are located in the uterine cavity (subendometrial fibroids) usually grow slowly, while uterine fibroids located in the uterine wall (mural fibroids) tend to grow faster.

2. High estrogen levels may cause uterine fibroids to grow rapidly

High estrogen levels are one of the important reasons why uterine fibroids continue to grow. Women often have higher estrogen levels before menopause, in early pregnancy, and when using hormone replacement therapy, which may cause uterine fibroids to grow faster.

3. Genetic factors may also affect the growth of uterine fibroids

Studies have shown that genetic factors also play a role in the growth of uterine fibroids. If multiple people in your family have uterine fibroids, you may also face a higher risk. Genetic factors may not only cause the occurrence of uterine fibroids, but also cause them to tend to grow larger.

Uterine fibroids grow at different rates under different circumstances. They tend not to grow larger after menopause, during pregnancy, and when treated with medication. However, factors such as the type of fibroid, estrogen levels, and personal genetics may cause it to continue to grow. Therefore, understanding the growth patterns of uterine fibroids and possible influencing factors can help you take appropriate treatment measures in a timely manner to avoid the discomfort and serious consequences they cause.
