The thickness of the endometrial lining during menopause is not accurately determined and should be judged in relation to the physical condition. If no hormonal drugs are used during menopause, the thickness of the endometrium will be about 4-5 mm, and there will be no recurrence of menstruation and no cyclical changes, and the endometrium will not continue to grow after the end of the last menstruation. After the loss of ovarian hormones, the endometrium is atrophied, the epithelial cells are relatively small, the secretions are reduced, and the thickness of the endometrium is basically thin. Many women will have abnormal conditions after menopause, such as the appearance of endometrial hyperplasia and endometrial lesions, which may exceed 5mm, and the thickness of the endometrium will be judged according to the actual situation.
