The serious consequences of lumbar slipped disc include nerve injury, cardiopulmonary function limitation and so on. 1. Nerve injury: the pathogenesis of lumbar spondylolisthesis is still unclear, and most scholars believe that it may be due to the congenital factors of lumbar spine as well as the degenerative changes of later life. Lumbar spondylolysis can cause spinal cord and nerve injury, abnormal muscle strength of both lower limbs, manifested as intermittent claudication; it can also cause cauda equina nerve compression, manifested as dysfunction of bowel movements; patients with necrotic nerve degeneration may also have the risk of paraplegia. 2. Cardiorespiratory function limitation: patients with lumbar spondylolisthesis may have changes in the spinal force line. Early symptoms may be characterized by pain and discomfort in the soft tissues surrounding the slipped vertebra. As the slip develops further, the spinal morphology gradually changes, such as the appearance of scoliosis and kyphosis of the spine. Patients with severe changes in spinal morphology can cause changes in the thoracic structure of the body, affecting the normal cardiopulmonary function of the patient. Slipped lumbar disc may also have other serious consequences, it is recommended to go to the hospital in a timely manner, improve the examination to clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
