Submucosal fibroids are a type of uterine fibroids. Submucosal fibroids are interstitial fibroids that grow into the uterine cavity and protrude into the uterine cavity and come into direct contact with the mucosal layer. Uterine fibroids are the most common type of benign tumor in the female reproductive organs. According to their relationship with the muscle wall, there are three types of fibroids: interstitial fibroids, subplasmic fibroids, and submucosal fibroids. If a submucosal fibroid is located in the uterine cavity, the uterus is uniformly enlarged, and if it is prolapsed from the ectocervix, a mass can be seen at the cervical opening. The clinical symptoms of submucosal fibroids are: 1. menstrual changes: the most common symptoms are shortened menstrual cycle, increased menstrual volume, prolonged menstrual period, irregular vaginal bleeding, etc. 2. 3. Infertility: Myoma distorts the fallopian tubes or distorts the uterine cavity so that the fertilized egg cannot be laid, resulting in infertility. 4.Secondary anemia: Long-term excessive menstruation may lead to secondary anemia, pale face, weakness and other symptoms. The treatment is based on the size and symptoms of fibroids. Therefore, for submucosal fibroids, first of all, regular review is necessary, and when symptoms appear, timely medical treatment is possible, and in serious cases, surgical removal is feasible.
