Physiological changes in women after 65 years old include bone loss, slowing down of metabolism and cessation of menstruation. 1. Decrease in bone mass: After 65 years old, women’s bone density usually decreases and the rate of bone loss accelerates. Therefore, it is necessary to take sunshine, calcium supplements in time, exercise appropriately, and pay attention to avoiding alcohol to prevent alcohol-induced bone calcium loss. Women should pay more attention than men to prevent the risk of osteoporosis. 2. Metabolism slows down: after 65 years old, the body’s activity and demand for energy will decrease, body temperature decreases, action slows down, and the amount of food decreases. 3. Cessation of menstruation: After 65 years old, women’s menstruation will stop because of the natural decline of ovarian function, the level of estrogen decreases, and the endometrium will no longer shed periodically, so menstruation will stop. There are many other physiological changes in women after the age of 65, such as decreased sleep, memory loss, and decreased frequency of bowel habits, and some older people may have a bowel movement once a week. If these symptoms occur on a daily basis, you should go to the hospital for examination to rule out other diseases before you can be sure that they are physiological symptoms.
