Risk factors for sciatica include:
- Age. Age-related changes in the spine, such as herniated discs and bone spurs, are the most common causes of sciatica.
- Obesity. Being overweight increases stress on the spine.
- Occupation. A job that requires twisting the back, carrying heavy loads or driving a motor vehicle for long periods might play a role in sciatica.
- Prolonged sitting. People who sit a lot or don't move much are more likely to develop sciatica than active people are.
- Diabetes. This condition, which affects the way the body uses blood sugar, increases the risk of nerve damage.
- Past history of lower back pain/sciatica. 35% of people who have lower back pain also experience sciatica. People who have experienced a significant bout of lower back pain and sciatica have a 90% reoccurrence rate.
