Herniated Discs
A herniation occurs when the outer band of the disc breaks or cracks, and the gel-like substance from the inside of the disc leaks out, causing pressure on the spinal canal or nerve roots. In addition, the nucleus releases chemicals that can irritate the surrounding nerves causing inflammation and pain.
Most lumbar disc herniations result from sudden stress, such as from an accident. Sometimes they occur gradually, over weeks, or even months. The risk factors that can contribute to the chances of a disc herniation include:
-
- Aging: As we get older, discs gradually dry out, losing their strength and resiliency.
- Lifestyle choices: Poor disc health is associated with a number of lifestyle factors, including a lack of physical activity, an unhealthy diet, excess body fat, and smoking.
- Poor posture and incorrect repetitive lifting or twisting can place additional stress on the lumbar spine.
