Causes of Lumbar Disc Herniation

The lower spine is composed of disc-like structures that are cushioned by soft gel-like sections in between them series of outer fibrous rings (annulus fibrosis) surrounding a gelatinous center (nucleus pulposus). The outer annular rings are thinnest posterior and lateral; most disc bulges occur at this location due to the weakness of the disc wall. The purpose of these sections is to promote flexibility and absorb the load of stress applied to the vertebra. Degeneration of these areas causes a loss of elasticity and a propensity to be torn or damaged, may lead to a condition called disc prolapse/disc herniation or slipped disc. The lumbar levels with the highest rate of disc degeneration and bulging are the fourth and fifth (L4-L5), and lumbar fifth and sacrum (L5-S1) levels. Vertebral subluxation is a major reason for Lumbar Disc Herniation.

Lumbar herniated discs are a widespread medical problem, most often affecting people age 30 to 50. Due to aging and general wear and tear, the discs lose some of the fluid that makes them pliable and spongy. As a result, the discs tend to become flatter and harder. This process is known as disc degeneration. When pressure or stress is placed on the spine, the disc’s outer ring may bulge, crack, or tear.


Age - The most common risk factor is being between the ages of 30 and 50.

Jobs that require heavy lifting and other physical labor have been linked to a greater risk of developing a lumbar herniated disc. Pulling, pushing, and twisting actions can add to risk if they’re done repeatedly.

Excess weight makes one more likely to experience a lumbar herniated disc and 12 times more likely to have the same disc herniate again, called a recurrent disc herniation.

Certain lifestyle habits affect the integrity of bones. Smoking, for example, decreases the amount of water in your discs, which are needed to absorb impact.

Road Traffic Accidents.

Repetitive stress injuries, like lifting or carrying heavy loads.

Sports Injuries.

Wrong sitting postures at Work place.

Frequent two wheeler riding.
