What exactly causes excessive menstruation? ① Female endocrine dysfunction: Due to a certain link of hypothalamic-pituitary-ovarian axis dysfunction, the follicular development of ovaries is affected, such as insufficient or excessive secretion of estrogen, ovulation disorder, no progesterone secretion, resulting in excessive growth of endometrium, when the amount of estrogen is not enough to maintain the growth of endometrium or a sudden drop, the endometrium sheds large pieces and leads to excessive menstrual blood. ②Submucosal fibroids or intermucosal fibroids, endometrial polyps may also cause excessive menstrual flow. ③ Blood system diseases, such as leukemia and thrombocytopenic purpura, can also cause excessive menstruation. ④Other, such as improper use of intrauterine device, contraceptive drugs, changes in living environment, emotional stimulation, etc. may have some influence. Therefore, if you have abnormal excessive menstrual flow, you should consult a doctor in time to find out the cause. What should I do if I have excessive menstruation? In the past, the treatment method was mainly conservative treatment such as medication and scraping. Once the treatment is stopped, the efficacy usually does not last, and serious side effects may occur after long-term application. Another option is the use of the Manned IUD, which can reduce the amount of menstruation, but many patients are reluctant to choose it due to the possibility of recurrent small amounts of bleeding. Finally, surgical treatment, such as hysterectomy and endometrial resection, may be considered. The disadvantages of hysterectomy, such as greater trauma, longer hospital stay, slower postoperative recovery, and some postoperative effects on ovarian function, often make it an option of last resort. Endometrial removal is the most popular minimally invasive procedure for patients in recent years, which has the advantages of short operative time, minimal trauma, and quick recovery. It has been developed to the 3rd generation of the surgical system — Noshu impedance-controlled endometrial resection system (“Noshu”), which is also the main choice of treatment for many patients. This minimally invasive procedure uses radiofrequency energy to remove the endometrium for the purpose of controlling menstrual cramps. The average treatment time for Nosur is about 90 seconds, and a single treatment can reduce the amount of menstrual bleeding or even amenorrhea. Nosur does not require premedication pretreatment and the procedure can be performed during the menstrual cycle. The procedure does not affect ovarian function, so female hormone secretion is not affected and does not cause premature aging in women; at the same time, the procedure preserves the uterus, away from the psychological and other effects of hysterectomy on patients. Most women have no pain after surgery and can resume their daily work and life the next day. Due to the short operation time and quick recovery, it is even more suitable for patients with combined serious medical diseases such as chronic renal failure, abnormal coagulation function, aplastic anemia, primary hypertension, and systemic lupus erythematosus.
