Why do you need progesterone for thick lining

Patients with thick endometrium can take progesterone medication in order to adjust the thickness of the endometrium.
The thickness of the endometrium is affected by estrogen and progesterone, and the thickness varies at different menstrual periods. Estrogen can cause the endometrium to proliferate and repair, while progesterone can inhibit the proliferation of the endometrium and make the endometrium thinner.
If the thickening of the lining is caused by disease, you can take progesterone medication to make the hyperplasia of the lining transformed into the secretory phase of the lining, and after stopping the medication, the hyperplasia of the lining of the uterus is shed, which can play the role of scraping, and the lining will become thinner.
However, it should be noted that progesterone is more effective for endometrial hyperplasia, but less effective for endometrial thickening caused by other diseases such as endometrial polyps and endometrial cancer. Therefore, before using progesterone to scrape the uterus, patients should do diagnostic scraping first, except for organic lesions, and then according to their own situation, under the guidance of the doctor targeted treatment.
