What Is Degenerative Disc Disease?
Degenerative disc disease is a term used to describe the natural breakdown of spinal discs that occurs with age. The intervertebral discs sit between the vertebrae and function as shock absorbers for the spine, allowing you to bend, twist, and move with flexibility. Over time, these discs can lose hydration and elasticity, making them less able to cushion the vertebrae effectively.
Degenerative disc disease most commonly affects the cervical spine (neck) and the lumbar spine (lower back), though degenerative changes can occur anywhere along the spinal column. When the outer portion of a disc bulges, the proteins within the disc space can irritate nearby nerves and trigger inflammation. The outer rings of the disc, called the annulus fibrosus, may also wear down to the point where they can no longer manage the stress placed on the spine, creating movement at the vertebral segment and contributing to pain.
It is worth noting that disc degeneration does not always produce symptoms. Some patients experience significant discomfort while others have little to none, even when imaging shows similar degenerative changes.
