Degenerative disc disease
Also called: DDD, disc degeneration, worn spinal discs
What it means
Degenerative disc disease (DDD) is the natural wearing down of the cushion-like discs between your spine bones (vertebrae), causing them to lose height and flexibility over time.
It can change your posture and spine shape, which matters alongside bone density when thinking about overall spine health and fracture risk.
Degenerative disc disease describes the gradual drying out and flattening of the intervertebral discs, the soft cushions that sit between each vertebra in your spine. As we age, these discs lose water content and elasticity, becoming thinner and less able to absorb shock. This is considered a normal part of aging rather than a true disease, though the name has stuck.
DDD mostly affects the lumbar spine and cervical spine, the areas that move and bear weight the most. It can lead to stiffness, localized back or neck pain, and sometimes nerve irritation if a disc bulges or narrows the space around the spinal cord, contributing to conditions like spinal stenosis. It is a separate issue from osteoporosis, but both can affect how the spine looks and feels, including height loss and changes in posture such as kyphosis.
There is no cure for disc degeneration, but doctors often manage it with a combination of pain relief, physical therapy, posture training, and targeted exercise. Core stability training and back extensor strengthening are commonly recommended to support the spine. Any decisions about treatment, imaging, or procedures should be made with your doctor, who can tailor a plan to your specific symptoms and spine health.
Spinal discs naturally wear down over time, changing posture and shape alongside bone density concerns.
