lumbar protrusion, also known as lumbar disc herniation, is a problem that many people may encounter. when a lumbar disc herniation compresses nerves, it can cause a series of uncomfortable symptoms, such as low back pain, numbness in the lower limbs, etc. so what are the common causes of nerve compression by the lumbar process? let’s talk about this topic below.

age factor

first, as we age, our intervertebral discs gradually lose moisture and elasticity. the intervertebral disc is like a small water cushion located between the vertebrae, providing cushioning and support. however, over time, this "water cushion" will become increasingly dry and brittle, prone to cracking. once it ruptures, the nucleus pulposus inside may protrude and compress surrounding nerves. this is why older people are more likely to suffer from lumbar disc herniation.

long-term bad posture

in modern life, many people maintain the same posture for long periods of time, such as sitting, standing or bending over for long periods of time. this bad posture will increase the pressure on the lumbar discs, which may lead to disc herniation over time. imagine if you hold a heavy object in one position all the time, your arms will definitely feel sore. the same is true for the lumbar spine. if it is in a state of tension for a long time, it is naturally prone to problems.
