Symptoms of osteoporosis include: pain, spinal deformation and the occurrence of fragility fractures are the most typical clinical manifestations of osteoporosis. However, many patients with osteoporosis often have no obvious conscious symptoms in the early stage, and are often found to have osteoporotic changes only after the fracture occurs by X-ray or bone density examination. Pain: Patients may have low back pain or peripheral pain, and the pain may increase when the load increases or the activity is limited, and in severe cases, there are difficulties in turning, sitting and walking. 2. Spinal deformation: Those with severe osteoporosis may have height shortening and hunchback. Vertebral compression fracture can lead to thoracic deformation, abdominal compression, affecting cardiopulmonary function, etc. 3. Fracture: A fracture occurs after mild trauma or daily activities as a fragility fracture. The common sites where fragility fractures occur are the thoracic and lumbar spine, hip, radius, distal ulna and proximal humerus. Fractures can also occur at other sites. After a fragility fracture, the risk of a second fracture increases significantly.
