Among gynecological diseases, uterine fibroids are by far the most common type of benign tumor in women and one of the most common tumors in the human body. Most patients with uterine fibroids are middle-aged women, aged 35 to 50 years. The cause of fibroids is related to excessive estrogen in the body, and long-term stimulation. So, what causes fibroids? The causes of uterine fibroids are still unknown, but a large number of clinical observations and experimental results prove that: 1. fibroids often increase in size due to pregnancy or application of estrogen. 2. They are often complicated by excessive endometrial hyperplasia. 3.The patient’s serum estrogen level is increased. The majority of fibroids are seen after puberty and gradually shrink after menopause. The binding force of myoma cells with estradiol is 20% higher than that of normal myocytes, so it is generally believed that the growth of uterine fibroids is closely related to estrogen. The common causes of uterine fibroids formation are mainly related to the following issues. One, unreasonable diet Women who are partial and picky eaters and meat-based women have a higher chance of developing uterine fibroids than women who have a balanced diet, and it is important to avoid excessive intake of hormone-based foods. The risk of uterine fibroids increases by 21% for every 10 kg of overweight women. Three, unreasonable contraceptive measures The constant stimulation caused by multiple flow C can also cause uterine fibroids, so it is important to do a good job of contraceptive birth control measures, but women who take the pill at an earlier age have a relatively high chance of developing uterine fibroids, and it is important to choose a reasonable and appropriate contraceptive measures. Fourth, environmental changes Environmental pollution or long-term work in a polluted, toxic environment, etc. is one of the reasons for the formation of uterine fibroids.
