The factors of lumbar disc herniation are many and complicated. Generally speaking, there are the following reasons: First, excessive waist weight and diffuse muscle strain, such as energetic employees, race walking and fitness exercises, long-term work with their heads down, often hanging things with their heads down or sitting for a long time, and persistent subacute injury to the waist, will increase the work pressure of the lumbar intervertebral disc, accelerate degeneration and aging, crack the fibrous ring, and cause lumbar disc herniation. Second, age, age is also the main factor of lumbar disc herniation, which is more common in middle-aged and elderly people, with an average age of about 40 years old. Thirdly, the hyperosteogeny and hypoplasia of lumbar vertebrae or the abnormal physiological curvature of lumbar vertebrae can accelerate the degeneration and injury of lumbar intervertebral discs and crack the annulus fibrosus.

The increase of keratin hydrochloride and the decrease of chondroitin content will increase the ductility of the fibrous ring of lumbar intervertebral disc, which is easy to be damaged and cause lumbar disc herniation. The specific clinical symptoms are low back pain, leg pain and backache, and there is obvious radiation pain in the area where the lumbar compression nerve operates. Lumbar disc herniation in the elderly is mainly due to the decrease of water content of chemical fibrocartilage tissue and the increase of ductility of chemical fibrocartilage tissue with age, which will be damaged under continuous working pressure. Other reasons, such as figure, heredity, pregnancy, long-term smoking, diabetic patients and other factors, are related to lumbar disc herniation.

Lumbar disc herniation is one of the common spinal diseases, and patients often have low back pain, sciatica, numbness and other diseases. There are many factors that cause lumbar disc herniation, most of which are caused by lumbar injury and diffuse muscle strain. The emphasis is on overload, long-term vibration, incorrect waist posture, degenerative diseases of lumbar intervertebral disc, trauma, etc., which may all cause lumbar disc herniation. Most people have heard of the disease of lumbar disc herniation, and many people are deeply involved in it, especially those wage earners. Because of their sedentary work, it is very easy to get lumbar disc herniation after a long time.

The common causes of lumbar disc herniation are as follows: First, it is caused by trauma related to lumbar vertebrae. This kind of thing is more common among young people. This kind of patients usually have a twisted waist or vertical compression of the spine. For example, the patient's head is hit by a hanging object, or the patient falls from a height, which will cause excessive compression and stimulation to the lumbar intervertebral disc, causing the fibrous ring to crack and the nucleus pulposus to protrude. Second, it may be caused by excessive lumbar exertion. It is usually common in patients with long-term weight bearing or standing for a long time, which will increase the load borne by the lumbar spine and accelerate the degeneration of the lumbar spine.
