Uterine fibroids usually lead to heavier periods, prolonged periods, and sometimes infertility. Uterine fibroids may be associated with abnormal sex hormones in the body and other factors. When fibroids enlarge, they may cause the lining of the uterine cavity to increase in size, which can lead to increased menstrual flow during menstruation and prolonged menstrual periods. Uterine fibroids may also lead to irregular vaginal bleeding and frequent bleeding, which may easily cause anemia, and sometimes affect women’s fertility and even cause infertility. Therefore, after the appearance of related symptoms, it is necessary to consult a doctor as soon as possible for examination, to clarify the severity of uterine fibroids, and to carry out reasonable treatment.
