Most of the patients come to the gynecology clinic because their periods have become less frequent and darker, while many patients who have heavy periods or even anemia do not come to the clinic or refuse to receive treatment. The reason for not seeing a doctor or not receiving treatment is that patients feel that heavy periods are normal and that light periods are abnormal. What is normal menstruation? Most women have regular menstruation after puberty, and a normal menstrual cycle is one that lasts from 24 to 35 days, about 2-7 days each time, and the volume of menstruation is about 20-60 ml. If the volume of menstruation exceeds 60 ml, it is excessive, and if it exceeds 80 ml, it is clinically diagnosed as excessive menstruation. anemia will occur. A woman suffering from anemia, in addition to gastrointestinal diseases such as ulcerative diseases, is most often caused by excessive menstrual flow. These patients often feel a decrease in resistance and are easily fatigued, which can increase the burden on the heart for a long time and is very harmful to physical and mental health. The causes of excessive menstruation may be related to gynecological diseases such as uterine fibroids, endometriosis, adenomyosis, and also to blood disorders such as idiopathic thrombocytopenia and the use of anticoagulants. If no uterine or systemic disease is found, idiopathic menorrhagia is diagnosed. Heavy menstrual flow is a common reason for gynecologic acceptance of hysterectomy, but there are various treatments for idiopathic heavy menstrual flow, such as antifibrinolytic drugs during menstruation, or oral short-acting contraceptives, or intrauterine devices with progesterone (Mannorrhea) that can reduce menstrual flow. When conservative treatment does not work, surgery is then considered.
