Spine Degeneration and Age: What the Numbers Show
Spine degeneration may be developing long before you notice any symptoms. In fact, imaging studies indicate that degenerative changes can be surprisingly common, even among people who feel perfectly well.
How Common Is Spine Degeneration?
A systematic review of imaging studies found that disc degeneration was visible in 37% of asymptomatic people aged 20 and 96% of those aged 80 (Brinjikji et al., American Journal of Neuroradiology, 2015).

The figures come from studies of asymptomatic individuals, meaning these imaging findings did not necessarily cause symptoms. The prevalence increased steadily with age, showing that degenerative changes can be a common part of ageing.
Sleep comfort is another consideration as we age. Choosing an orthopaedic mattress suited to individual support and comfort preferences may help create a more comfortable sleep surface.
Why Can Spine Degeneration Go Unnoticed?
-
Degenerative changes can develop gradually, without causing immediate or noticeable symptoms.
-
Some people may have changes in the discs or joints without experiencing pain or movement problems.
-
Symptoms, when they occur, can vary depending on the type and extent of spinal changes.
-
This is why the presence of age-related changes does not necessarily mean that a person will experience symptoms.
Who Is More Likely to Experience Spine Degeneration?
-
Older adults: Degenerative changes become more common with age.
-
Physically demanding routines: Repeated physical strain may be associated with spinal changes.
-
Sedentary routines: Prolonged sitting and low activity may contribute to stiffness and reduced mobility.
-
Previous spinal injuries: Earlier injuries may influence how the spine changes over time.
-
Individual factors: Genetics, body weight, activity levels, and lifestyle may also play a role.

FAQ's
1. Does having degeneration on a scan mean I'll have pain?
No, degenerative changes seen on imaging do not always cause pain or other symptoms.
2. Does everyone eventually get spine degeneration?
Age-related disc changes are very common, but their severity and associated symptoms can vary between individuals.
3. Is spine degeneration more common in men or women?
Degenerative changes can occur in both men and women. Prevalence can vary depending on the specific spinal condition and age group.
