If the thickness of the endometrium is less than 0.5cm, it is clinically menopausal, mainly because the ovarian function has declined, and the secretion of oestrogen will decline significantly, which will lead to genital atrophy, and the endometrium will become thinner. If the endometrium is abnormally thickened after menopause, and the thickness exceeds 0.5cm, it may be caused by endometrial pathology, which should be taken seriously, and diagnostic curettage is necessary to give the corresponding diagnosis. In addition, menstrual disorders will occur in the perimenopausal period, and the symptoms of menopause will appear in the clinic. The endometrial lining is thinner after menopause, which is a normal physiological phenomenon. After menopause, if there is an increase in vaginal discharge, irregular bleeding, etc., it is necessary to go to the hospital for examination in time.
