Is a disc desiccation the same as herniated disc?

No. Disc desiccation is not the same as a herniated disc. Disc desiccation refers to a degenerative condition in which a spinal disc loses fluid content and becomes dehydrated, leading to a decrease in its height. This can cause back pain and stiffness. On the other hand, a herniated disc, also known as a slipped or ruptured disc, occurs when the soft inner part (nucleus pulposus) of a spinal disc pushes out through a tear in the tough outer layer (annulus fibrosus). This usually happens when excessive pressure is placed on the spine. Disc desiccation and disc herniation are both common causes of lower back pain, but they have different causes and treatments.
