If a woman finds that her endometrium is thick and her menstrual flow is low, she needs to pay attention to the possibility of endometrial lesions or endometrial hyperplasia and not to be too nervous and scared. It is necessary to consider the use of pharmacological scraping in combination with the patient’s age and the specific thickness of the endometrium, i.e. to supplement the progesterone in the female body according to the normal therapeutic dose, and then stop the medication and wait for the endometrium to shed to reach the thickness of the endometrium that should be present after the menstruation is clean. The female endometrium and menstrual volume change with the changes in the level of estrogen and progesterone secretion in the body. If you find that the endometrium is thick, the menstrual flow is low, irregular vaginal bleeding often occurs during non-menstrual periods, and oral progestin does not work, it is recommended that you go to the hospital for endometrial scraping to see if there are endometrial lesions that cause excessive thickness, and then undergo pathological examination based on the scraped endometrium and decide whether to use medication or surgery based on the pathological examination results.
