Causes of disk herniation, spinal injury, Risk factors for a herniated disc.
Among the main causes of a herniated disc, you can mention two:
Age-related changes in the disc
Injuries to the spine
Despite its strength in the intervertebral disc, there are two so-called "Weaknesses": In the intervertebral disc is not a network of blood vessels. Food drive is carried out by diffusion ("soaking") through the vertebrae surrounding tissue. At the same nutrients more actively enter the disk at a time when there occur variations in pressure (ie, motion in the spine).
The usual way of life does not provide the necessary motor load on the spine, so the shortage of movements leads to a deterioration in nutrition of the intervertebral discs, and, consequently, a decrease in its strength and rupture.
The structure of the fibers of the fibrous ring of the disc is designed for a certain amount and direction of movement of spine. If the direction and amount of physical activity on a disk different from the norm. There is a gradual destruction of the fibrous ring. This process can take years, and the "last straw" can be an awkward movement, sneezing or physical exertion.
How is a spinal injury
Injury to the spine can cause a sudden sharp blow, or increased pressure on the spine. Sometimes an injury can cause flexion or extension. This leads to increased pressure inside the disc, resulting in a nucleus pulposus disk goes through the cracks.
In addition, spinal injury, namely, fibrous disk, can cause permanent monotonous motion, for example, weight lifting, prolonged vibration or sports injuries.
Risk factors for herniated disc
All risk factors can be divided into those that can be avoided and those that can not be avoided.
Risk factors that can not be avoided, include:
The natural aging process. With the aging and wear of the intervertebral discs, they are easier to injury.
The female sex. It was noted that women have a herniated disc occurs frequently.
Transferred back injury, surgery and disc herniation.
Risk factors for which we can influence through lifestyle changes or medication:
Work or other physical activity that increases the risk of disc herniation, such as prolonged sitting, frequent heavy lifting, frequent bending of the spine, generally heavy physical exertion, repetitive motion or repeated vibration.
Lack of regular exercise, which reinforce the ligaments of the spine and intervertebral discs, or persistent classes after a long absence of the load.
Smoking. Smoking and other bad habits can lead to poor nutrition of the intervertebral discs.
Obesity and overweight. Has not yet been scientifically proven for certain that he has an overweight load on the spine, but in addition, obesity itself decreases the ability to exercise.
