What is a thinning disc?
In the same way that muscles get smaller and bones get weaker as we age, the soft cushion-like discs that separate the bones of the spine begin to deteriorate. They begin to lose water content within the gel-like center, and the disc’s tough outer wall can become brittle and weak.
This combination reduces the disc’s ability to serve as the shock absorber between vertebrae. The resulting pressure from the vertebrae above and below can lead to a bulging or herniated disc.
