L5/S1 disc herniation refers to a herniated disc between the 5th lumbar vertebra and the 1st sacral vertebra, which may be related to lumbar degeneration, chronic injury, pregnancy and other causes. 1. Degenerative changes of the lumbar spine: because the intervertebral disc tissue bears the weight of the human torso and upper limbs, and because there is only a small amount of blood supply in the annulus fibrosus of the intervertebral disc, it is prone to degeneration, and with the growth of age and external stimulation, the degenerated disc is prone to protruding into the spinal canal. 2. Chronic injury: due to long-time physical labor, driving, sedentary stooping and other factors, can cause cumulative damage to the intervertebral discs and surrounding tissues, which can easily lead to disc herniation with the accumulation of time. 3. Pregnancy: weight gain during pregnancy, the whole ligament system is in a state of relaxation, the relaxation of the posterior longitudinal ligament can easily make the intervertebral disc bulge, which can lead to symptoms such as low back pain in pregnant women. When L5/S1 disc herniation occurs, it is recommended that the patient consult a doctor in a timely manner, follow the doctor’s instructions for further examination, and carry out targeted treatment or therapy with the help of the doctor.
