Uterine fibroids are the most common benign tumors of the female genitalia, and studies have found that about 20% of women between the ages of 30 and 50 have fibroids, and the disease has been on the rise in recent years. Although uterine fibroids are benign tumors and most of the symptoms are not obvious, they can endanger several organs of the body and cause infertility if not detected in time, so early prevention and treatment is very necessary. Uterine fibroids can be clinically divided into the following three types according to the growth site: interstitial fibroids located in the myometrium, which are the most common and account for 60-70 percent of the total; fibroids growing toward the uterine plasma membrane and protruding from the uterine surface are called subplasma fibroids, accounting for 20-30 percent of the total; fibroids growing toward the mucosal layer and protruding toward the uterine cavity are called submucosal fibroids, accounting for 10-15 percent of the total. Uterine fibroids vary greatly in size, from small ones that are indistinguishable to the naked eye to huge ones that can reach tens of kilograms. The most common symptoms of fibroids are menstrual changes, such as shortened menstrual cycle, prolonged menstruation or increased menstrual flow, especially heavy bleeding in a short period of time, which can cause severe anemia in patients. When the fibroids increase in size, they can press on the adjacent organs and cause frequent urination, constipation, ureteral effusion and hydronephrosis. In general, fibroids do not cause pain, but if subplasma fibroids twist, they can cause acute abdominal pain; submucosal fibroids can stimulate contractions and cause spasmodic pain, and when the fibroids are red and degenerative, they can cause severe pain. Uterine fibroids can also cause increased leucorrhea and infertility. There are also people who have no discomfort and are found to have fibroids when they have an ultrasound gynecological examination. Can I take natural phytoestrogens if I have fibroids? As we all know, hormone replacement therapy has been the treatment for female gynecological and endocrine disorders, but the long-term use of chemical hormones can easily induce the development of estrogen-related tumors, fibroids, especially breast cancer and endometrial cancer. Current research has found that estrogen-like activity in natural plants such as soy as well as Pueraria Mirifica can be found in animals and humans with weak estrogenic effects. So, how safe is it? Studies have shown that soybean and Pueraria Mirifica have weak estrogen-like activity and have a bidirectional effect on estrogen action levels, with soybean and Pueraria Mirifica acting as estrogen-like agents when there is a lack of estrogen in the body and having no significant effect on normal estrogen levels. The level of estrogen action is kept in balance. In addition, domestic and international studies have shown that isoflavones can not only regulate female endocrine secretion, but also promote bone formation and prevent cardiovascular diseases, yet their activity is not sufficient to cause the rise of estrogen levels and the occurrence of estrogen-related tumors or cancer. It can be concluded that natural soybean and Pueraria Mirifica extracts, as alternatives to estrogen, can play the role of estrogen on the one hand, but on the other hand, they are safe and do not induce estrogen-related diseases, can relieve women’s endocrine disorder symptoms and nourish women’s bodies in a safe and effective way. For patients with uterine fibroids, they can be taken except for those whose doctors recommend surgery. So, how should fibroids be treated? There are two types of fibroids: surgical treatment and conservative treatment. Doctors mostly consider the treatment plan comprehensively according to the patient’s age, fertility requirements, clinical symptoms, size and location of fibroids, etc. Surgery can be considered in the following cases: any uterus enlargement larger than 3 months of gestation, or obvious symptoms of pressure, or excessive menstrual flow, resulting in secondary anemia, are indications for surgery. Young infertile women with fibroids can be treated conservatively if they have no obvious symptoms and the size of the uterus is less than the third trimester of pregnancy. For the diagnosis of uterine fibroids, the more reliable method at present is through ultrasound examination combined with internal gynecological examination, which is both simple and painless.
