Osteoporosis is a disease in which bones become thinner, weaker, and more prone to fractures, and women are prone to this disease. Bone density, which refers to the density of bone trabeculae, reaches a high level in most women at age 18 and peaks at age 30. after age 30, bone density begins to decline at a steady rate, and the rate of bone loss increases significantly after menopause, with up to 20% of bone loss occurring within 5-7 years after menopause. Because of the continuous bone loss, bones become thinner and more fragile, which makes fractures more likely to occur, especially in women, with one in two people (in their lifetime) experiencing a fracture due to osteoporosis, especially a fracture of the femoral neck. The loss of height due to osteoporosis is not obvious at first, so young women generally think that osteoporosis is only a disorder seen in old age. In fact, up to 1/5 of bone mass is lost within 5-7 years after menopause. When a person has significantly less bone mass than normal, a condition of low density or bone deficiency occurs; if further bone loss occurs, the bone structure may become deformed, which is known as osteoporosis. There are many risk factors for osteoporosis, including aging, family history of osteoporosis, predisposition of white or Asian people (including Chinese), slender people, early menopause, smokers, alcoholics, sedentary (inactive lifestyle) white-collar workers, etc. It is also associated with some chronic diseases, such as hyperthyroidism, hyperparathyroidism, diabetes, etc. Taking anti-d epileptic drugs and corticosteroids also contribute to the The onset of the disease is also prompted by the use of antiepileptic drugs and corticosteroids. Early detection of bone loss in susceptible people is important, and a healthy lifestyle and early intervention are important measures to prevent osteoporosis, and adherence to reasonable treatment is essential to prevent aggravation of osteoporosis and to the health and quality of life of the patient throughout his or her life.
