Endometrial hyperplasia is commonly seen in middle-aged women over 35 years of age. Menstrual disorders are one of the prominent symptoms of this disease, often manifested as irregular vaginal bleeding, sporadic menstruation, amenorrhea or bleeding that does not stop after a period of amenorrhea. It is generally referred to as anovulatory dysfunction. In addition to vaginal bleeding, infertility is also a major symptom in patients with reproductive anovulatory dysfunction. During bleeding, there is usually no abdominal pain or other discomfort, but a large amount of blood or a long duration of bleeding may cause anemia in women, and rapid and heavy bleeding may lead to shock. Therefore, menopausal women who experience irregular vaginal bleeding and other menstrual disorders must seek medical attention in a timely manner, rather than treating it as a normal part of menopause or even taking medication to stop the bleeding. Different types of endometrial hyperplasia have different treatment principles: simple and complex endometrial hyperplasia: young patients: mostly non-ovulatory gonorrhea, basal body temperature should be measured, and those who are really monophasic non-ovulatory can be treated with ovulation promotion. Reproductive phase: Generally, bleeding can be controlled by scraping the uterus once. If there is still bleeding after scraping, hysteroscopy and ultrasound should be performed to exclude submucosal myomas or other organic lesions. The reproductive phase may also be sterile and clinically manifested as polycystic ovary syndrome, which is treated as polycystic ovary syndrome. Transitional menopause: often anovulatory. If menstruation is sporadic and the blood volume is high or the bleeding is prolonged after curettage, periodic progesterone therapy should be given every two months for a total of three cycles and then followed up for observation. Late menopause: should ask if estrogen-only replacement therapy is used. Replacement therapy may be suspended or progestin may be added after curettage.
