Causes:
1. Aging: The primary cause is the natural aging process, leading to wear and tear on spinal discs.
2. Genetic Factors: Genetic predisposition can play a role in an individual's susceptibility to disc degeneration.
3. Trauma or Injury: Previous injuries or trauma to the spine, even if occurring earlier in life.
4. Smoking: Smoking has been linked to accelerated disc degeneration, possibly due to reduced blood flow to the discs.
5. Spinal Instability: Instability in the spine, often resulting from the loss of disc height, can contribute to DDD.
6. Occupational Factors:: Jobs that involve repetitive lifting, bending, or other activities that strain the spine may increase the risk.
