Endometrial hyperplasia and polycystic ovaries are not the same disease, but polycystic ovary syndrome may lead to the appearance of endometrial hyperplasia. Endometrial hyperplasia is a disease in which the thickness of the lining of the uterus increases due to a number of factors, including endocrine dysfunction, intake of estrogenic substances, and obesity. Polycystic ovary syndrome is a gynecological endocrine disease, the cause of which is not yet clear, but most patients have elevated androgen levels, so the two are not the same disease. However, because polycystic ovary syndrome will lead to irregular ovulation or non-ovulation of the ovaries, which in turn leads to a lack of progesterone in the body, and is unable to antagonize the effect of estrogen to stimulate the endometrium to continue to proliferate, so there will be changes in the endometrium thickening. For women who are found to have endometrial hyperplasia or polycystic ovaries, it is recommended that they go to the gynecology department of a regular hospital and be actively treated under the guidance of a doctor.
