What are the causes of uterine fibroids? These are the ones you have to watch

Uterine fibroids are common benign uterine tumors in women. There are generally many factors that cause uterine fibroids. The most important reason is that the body is too fat, or uterine and ovarian dysfunction with age can also cause uterine fibroids, which is harmful to health and should be treated in time.

Causes of uterine fibroids

1. Obesity

Studies in recent years have found that obesity is positively correlated with the incidence of uterine fibroids. And every 10kg increase in weight for women can increase the risk of uterine fibroids by 21%, and every 1 unit increase in body mass index can increase the risk of uterine fibroids by 6%.

2. Age

Late childbearing age is often considered a high-risk age for the development of uterine fibroids.

This age is usually around 40 years old, close to perimenopause. During this period, there may be ovarian ovulation dysfunction. It may also be the result of the cumulative effects of estrogen and progesterone on women for 20 to 30 years during this period.

(III) Oral contraceptives

Current studies have found that whether oral contraceptives can increase the incidence of uterine fibroids depends mainly on the estrogen and progesterone components of the oral contraceptives.

If the oral contraceptive contains high-efficiency, high-dose progestin as the main ingredient, it can reduce the incidence of uterine fibroids; otherwise, it can increase the incidence of uterine fibroids.

If oral contraceptives are used at an early age (<13-16 years old), the incidence of uterine fibroids can be significantly increased.

4. Diet

Although the correlation between diet and the incidence of uterine fibroids often does not attract people's attention, studies have reported that women whose staple food is animal food have a significantly higher incidence of uterine fibroids than women whose staple food is green vegetables.

In addition, eating more vitamins, especially vitamin C, can also reduce the incidence of uterine fibroids.

5. Racial differences

Studies have shown that the incidence of uterine fibroids in black Americans is 3.4 times that of white people. The incidence of uterine fibroids in Orientals is lower than that in Westerners.

Further research found that African Americans have high levels of estrone, estradiol and free estradiol in their bodies, which may promote the occurrence of uterine fibroids.

(VI) Mental factors:

Excessive work stress, excessive pressure, family discord, emotional trauma, bad mood, etc. may cause ovarian dysfunction and lead to uterine fibroids.

(VII) Smoking

The harm of smoking to human health is well known. But studies have found that smoking can reduce the incidence of uterine fibroids.

It is generally believed that the incidence of uterine fibroids in women who are still smoking can be reduced by 50% compared with non-smoking women. The amount of smoking is negatively correlated with the incidence of uterine fibroids.
