As we age, all organs, tissues and systems of the human body are slowly aging, which is reflected in the degeneration of the lumbar spine, mainly manifested as lumbar disc herniation and lumbar spinal stenosis. People can walk around normally every day, weight-bearing, the lumbar spine plays a big role. “When the human body moves upright, the external pressure as well as the body’s own weight is exerted on the lumbosacral region. The intervertebral disc is the cartilage between the joints of the spine, and when the body is under pressure, it can be compressed and deformed like a rubber ball to relieve the pressure, thus protecting the safety of the joints of the spine. Once the external pressure is removed, the intervertebral disc returns to its original shape.” As the body ages, the intervertebral discs are becoming less flexible and recover more and more slowly from pressure and deformation, and if they are subjected to excessive pressure, it is easy to trigger a herniated disc. “Then come to the spinal canal. The vertebral canal is like a pipe in which a large number of nerves are distributed. The cross-section of the spinal canal in healthy adults is triangular in shape, but as the body ages, the spinal canal slowly deforms into a triangle with concave sides, which can squeeze the nerves inside and lead to lower back pain.” Mild elderly patients with lumbar disc herniation or lumbar spinal stenosis must do a good job of prevention and health care, as follows: 1, maintain correct sitting posture. 2, reasonable diet. Eat less greasy food and more fruits and vegetables. 3, enhance physical fitness. Exercise helps to restore the function of the lumbar disc, but some exercises are not suitable for patients with lumbar disc herniation or lumbar spinal stenosis, it is recommended to consult a professional physician.
