Man Yuele refers to levonorgestrel intrauterine device. Frequent endometrial thickening and low menstrual flow, endocrine disorders caused by endocrine disorders after diagnostic scraping can be treated by taking dextroprogesterone tablets, or levonorgestrel intrauterine sterilization system. Normal endometrium is stimulated by estrogen and progesterone, estrogen stimulates the endometrium to proliferate, progesterone stimulates the endometrium to enter the secretory phase and then fall off, only the ratio of estrogen and progesterone is normal, can produce normal menstruation. Endometrial thickening is most common in adolescent or menopausal women with irregular menstruation, mainly caused by long-term high estrogen, which stimulates overgrowth of the endometrium. Deferiprone is a progestin-like drug that can be given during the second half of the menstrual cycle to treat endometrial thickening. Progesterone can cause the endometrium to change from the proliferative phase to the secretory phase, causing the endometrium to shrink, and after the drug is stopped, the endometrium will be rapidly shed, so clinically it is called medicated curettage. Intrauterine placement of levonorgestrel intrauterine sterilization system, which contains highly effective progesterone, can slowly release progesterone, so that the endometrium lining becomes thinner and the menstrual flow is significantly reduced. It is also effective in treating endometrial thickening. Endometrial hyperplasia is a reversible endocrine system disease, can be under the guidance of the doctor to choose the appropriate way, standardized treatment, regular review, most of them can be treated.
