What happens to the intervertebral disc when decompression occurs?

When decompression occurs in relation to the intervertebral disc, the correct understanding is that the pressure within the disc decreases. Decompression can happen through various chiropractic adjustments or other therapies designed to relieve pressure on the spinal structures.

During this process, the reduction of external pressure allows the disc to expand and become more hydrated as it draws in fluid and nutrients from its surrounding environment. This is particularly important because the intervertebral discs do not have a direct blood supply; instead, they rely on the movement of fluids to maintain health and function.

Consequently, decreased pressure is beneficial in promoting the overall health of the intervertebral disc. It facilitates the proper exchange of fluids and nutrients, which can help reduce pain and improve mobility. Enhanced mobility can be a result of decreased pressure, but it is a secondary consequence rather than the primary event occurring in the disc itself during decompression.
