What can result from dehydration of intervertebral discs?

Dehydration of intervertebral discs leads to decreased disc height and flexibility. The intervertebral discs are composed largely of water, and their primary function is to act as shock absorbers between the vertebrae, providing both cushioning and flexibility. When these discs become dehydrated, they lose water content, which results in a reduction of their height. This can lead to a decrease in the space between vertebrae, potentially resulting in increased pressure on spinal nerves and adjacent structures. Furthermore, reduced hydration affects the discs' ability to withstand forces, making them less flexible and more susceptible to injury. Thus, the correct choice reflects the physiological consequences of dehydration on intervertebral discs, impacting overall spinal health and function.
