There is no direct correlation between diabetes mellitus and lumbar disc herniation, but it may cause similar symptoms, such as numbness in the lower limbs. The causes of lumbar disc herniation mainly include the following aspects: congenital developmental abnormality, trauma, disc degeneration and so on. 1. Abnormal congenital development: abnormal congenital development of lumbar intervertebral discs is likely to cause instability of the annulus fibrosus, which further leads to lumbar intervertebral disc herniation. 2. Trauma: Violent trauma may lead to rupture of the annulus fibrosus, causing the nucleus pulposus to protrude outward and causing related symptoms. 3. Intervertebral disc degeneration: with age, the annulus fibrosus becomes brittle and the nucleus pulposus becomes dehydrated, which can lead to lumbar disc herniation with weight bearing. On the whole, the relationship between lumbar disc herniation and diabetes is not close, obvious lumbar discomfort, lower limb numbness symptoms, you need to consult a doctor in a timely manner to check the diagnosis of the condition under the guidance of the doctor to carry out standardized treatment, to avoid causing delays in the condition.
