Introduction Osteoporosis (osteoporosis) is a group of bone diseases caused by a variety of causes, bone tissue with normal calcification, calcium salts and matrix in a normal ratio, characterized by a decrease in the amount of bone tissue per unit volume of metabolic bone lesions. Clinical manifestations: 1, pain: the most common symptom of primary osteoporosis, low back pain is common, accounting for 70%-80% of patients with pain. 2.Shortening of body length and hunchback: mostly appear after pain. 3.Fracture: This is the most common and serious complication of degenerative osteoporosis. 4.Decreased respiratory function: compression fractures of thoracic and lumbar vertebrae, backward curvature of the spine, and thoracic deformity can significantly reduce lung capacity and maximum air exchange, and patients can often experience chest tightness, shortness of breath, and difficulty in breathing. Causes: Osteoporosis is a disease of systemic bone metabolism disorder with impaired microstructure of bone tissue, decreasing ratio of bone mineral components and bone matrix, thinning of bone mass, decreasing number of bone trabeculae, increasing bone fragility and increasing risk of fracture. Experts pointed out that the external magnetic field stimulation is to prevent a large loss of bone calcium, maintain the body sufficient bone density is the most effective way to prevent and treat osteoporosis! Treatment misconceptions: As we age, the risk of osteoporosis in the elderly gradually increases. Since osteoporosis brings pain and can easily lead to osteoporotic fractures, it makes the elderly fearful of osteoporosis, and coupled with the exaggerated propaganda on the role of calcium supplementation in advertisements, many elderly people begin to blindly supplement calcium. Usually, elderly people over the age of 60 need to take 800 mg of calcium per day. Calcium supplementation alone does not allow the bones to be fully absorbed, if the calcium level in the blood is too high. It can lead to hypercalcemia and can cause complications, such as kidney stones and vascular calcification, which endanger the health of the elderly.
