Degenerative Disc Disease refers to what process?

• A. Gradual degeneration of the disc over many years
• B. Acute inflammation of the disc
• C. Infection of the disc
• D. Discs turning to bone

Answer: (A)

Degenerative Disc Disease describes a chronic, progressive wear-and-tear process of the intervertebral discs that occurs over many years, often linked to aging and repetitive spinal loading. Over time the nucleus pulposus loses water and the annulus fibrosus develops fissures, leading to reduced disc height and stiffness. This gradual degeneration can contribute to pain and reduced mobility and may sometimes contribute to nerve irritation if structural changes like herniation or bone spur formation occur, but the hallmark is slow, long-term change rather than an acute event. It is not an acute inflammatory condition, an infection, or a process where discs turn into bone, which is why those other descriptions do not fit.
