After menopause, the level of estrogen in the body decreases, and the thickness of the endometrium will become thinner, generally less than 0.5cm is normal. After menopause, due to the decline of ovarian function, the level of estrogen and progesterone in the body decreases, and the extremely low level of estrogen and progesterone is not enough to promote the growth and shedding of the endometrium to form menstruation, so it leads to the thinning of the endometrium after menopause. Generally speaking, the normal thickness of the endometrium after menopause is usually less than 0.5cm. If the thickness of the endometrium after menopause reaches or exceeds 1cm, it often suggests endometrial pathology, which requires patients to pay great attention to, and promptly consult a doctor to improve the relevant examinations and standardize the treatment.
