Osteoporosis is a group of bone diseases caused by multiple causes, characterized by normal calcification of bone tissue and a normal ratio of calcium salts to matrix, but a decrease in the amount of bone tissue per unit volume, a metabolic bone lesion. In most cases of osteoporosis, the decrease in bone tissue is mainly due to increased bone resorption. The symptoms of osteoporosis manifest mainly as the following: 1. Pain. This is the most common symptom of osteoporosis, with low back pain being the most common. The pain generally spreads along the spine to both sides and worsens with activity. 2, fracture. When osteoporosis, bone density is reduced, bone toughness is reduced, and fractures are likely to occur under the action of external forces, such as falls in elderly people with osteoporosis may lead to fractures, which is also the most common and serious complications of degenerative osteoporosis. 3. Shortening of height and severe hunchback. Due to the high weight of the front vertebrae of the spine, especially the 11th and 12th thoracic vertebrae and the 1st lumbar vertebrae, the load is greater, and it is easy to compress and deform when osteoporosis occurs, which makes the spine tilt forward and form a hunchback. 4. Weakened respiratory function. When the thoracic and lumbar vertebrae compression fracture, the backbend of the spine and the deformation of the thorax can make the lung capacity and maximum gas exchange significantly reduced, and patients can often have symptoms such as chest tightness, shortness of breath and difficulty in breathing. The above four are the common symptoms of osteoporosis. When the above symptoms are found, you need to go to the hospital in time to avoid aggravating the disease and delaying the treatment.
