Low Back & Pelvis

What It Is

Just about everyone will have some type of lower back pain at some point in their lifetime. Pain can range from mild to severe. It can last for a long time or be short-lived. Whatever the cause, pain in the lower back can make many normal everyday activities difficult.

Changes in the discs are a normal part of ageing. Signs of disc change can be seen as early as the teenage years (Urban and Roberts, 2003), and almost everyone has some disc degeneration after the age of 40, even if it causes no symptoms (Cleveland Clinic, 2025). The soft centre of each disc (the nucleus) is around 80% water, and it is surrounded by a tough outer ring of fibrocartilage known as the annulus (Urban and Roberts, 2003). As we get older, the centre of the disc naturally loses some water, so the disc becomes thinner and does not absorb shock as well (Cleveland Clinic, 2025). This drying out is an early part of degeneration. Small cracks can appear in the outer ring, and the disc may bulge outwards. If the outer wall cracks open, disc material can push out (a herniated, slipped or prolapsed disc), which may press on a nerve (Cleveland Clinic, 2025; Urban and Roberts, 2003). Despite its name, degenerative disc disease is not really a disease but a condition in which the discs wear down; when more than one disc is affected it is called multilevel degenerative disc disease (Cleveland Clinic, 2025).

Causes of Degenerative Disc Disease

  • Hereditary/Genetic: disc disease can run in families, so if a parent, brother or sister has it, you are more likely to get it too (MedlinePlus Genetics, 2016).
  • Ageing (wear and tear): disc changes become more common as we get older (Urban and Roberts, 2003; Cleveland Clinic, 2025).
  • Smoking and excess weight: both are linked to a higher risk of disc degeneration (Urban and Roberts, 2003; MedlinePlus Genetics, 2016).
  • Heavy physical work and injuries: a physically demanding job, heavy work, and acute injuries such as falls can increase the risk (Cleveland Clinic, 2025; Urban and Roberts, 2003).

Degenerative Disc Disease Anatomy

Your spine is made up of many bones (vertebrae) stacked on top of each other. Ligaments, muscles, intervertebral discs and nerves are also part of your spine. The vertebrae connect to create a canal that protects the spinal cord. The spine has three main sections: the neck (cervical), the chest (thoracic) and the lower back (lumbar). Below the lower back, the base of the spine is made of vertebrae fused together.

In between each vertebra is a disc. It is made up of a soft inner part called the nucleus, and a tougher outer part called the annulus. The inner part is mostly water. When the disc starts to degenerate, the inner part dries out and the disc loses water. Small cracks can appear in the outer part of the disc, and the disc material can push out through these cracks; this is known as a slipped disc (or disc prolapse) (Cleveland Clinic, 2025).

The nerves (electrical cables) travel through the spinal canal and carry messages between the brain and the muscles. They branch away from the spinal cord through openings between the vertebrae. Ligaments and muscles give stability and support to the spine, and strong ligaments connect the vertebrae and help keep the spinal column in its proper position.
