Postmenopausal estrogen is still high considering that it is related to diet, medication, disease and other factors. 1. Diet: After menopause, patients may suffer from hot flashes, sweating, fatigue and other discomforts, and some of them may increase the amount of estrogen-rich foods and cause high estrogen levels. 2. Taking medication: some patients are more concerned about their menstruation and may use estrogen and progesterone preparations after menopause to maintain the balance of endocrine secretion in the body, and taking these medications may also cause high estrogen levels. 3. Diseases: (1) For some patients with premature ovarian failure, in order to maintain endocrine stability, the hypothalamus and pituitary gland may secrete excessive gonadotropins and act on the ovaries, thus leading to high estrogen levels. (2) For patients with estrogen-dependent breast cancer and ovarian cancer, their estrogen levels may also be elevated. (3) Certain ovarian tumors that can secrete estrogen can also cause high estrogen levels after menopause. For patients with high estrogen level after menopause, considering that it is related to the above factors, it is recommended that patients go to the gynecology department of regular hospitals as soon as possible for consultation, so as to clarify the cause of the disease and then take active treatment under the guidance of doctors.
