Lumbar osteoporosis usually has symptoms such as pain, hunchback and decreased respiratory function. 1. Pain: Generally lumbar pain is more common, the pain spreads along the spine to both sides, the pain is reduced when the patient is lying on his back or sitting, and the pain is aggravated when he is standing upright or leaning backward. The pain usually decreases during the day and increases at night and when waking up in the morning. 2. Hunchback: the front part of the vertebrae is the pillar of the body and carries a great burden. Osteoporosis of the lumbar vertebrae makes it easier for this part to be compressed and deformed, which makes the spine tilt forward and the curvature of the back intensify, forming a hunchback. 3. Decreased respiratory function: Thoracolumbar compression fracture and thoracic deformity can significantly reduce lung capacity, and patients usually have symptoms such as chest tightness, shortness of breath and dyspnea. If patients experience the above symptoms, they should actively seek medical attention to avoid delaying their condition.
