After menopause, it is advisable for a woman to have her bone mineral density tested, so that she can understand her bone quality and so on. Menopause refers to the permanent cessation of menstruation due to the failure of ovarian function, and is usually recognized as menopause after 12 consecutive months of menopause. Menopause usually begins with irregular menstrual cycles, followed by hot flashes, sweating, mood swings, vaginal dryness and pain. Women may experience a decrease or lack of estrogen levels after menopause. Decreased estrogen will increase bone resorption and lead to rapid bone loss, which may lead to osteoporosis, pain in the lower back and limbs, etc. Therefore, it is necessary for women to test their bone density after menopause. It is recommended that postmenopausal women take a bone density test once a year, eat more calcium-containing foods, such as milk, soy products, etc. Women with serious bone density loss can take vitamin D, calcium carbonate and other medications under the guidance of a doctor for treatment.
