Risk factors
By Mayo Clinic staffRisk factors for sciatica include:
- Age. Age-related changes in the spine, such as herniated disks and bone spurs, are the most common causes of sciatica.
- Obesity. By increasing the stress on your spine, excess body weight may contribute to the spinal changes that trigger sciatica.
- Occupation. A job that requires you to twist your back, carry heavy loads or drive a motor vehicle for long periods may play a role in sciatica, but there's no conclusive evidence of this link.
- Prolonged sitting. People who sit for prolonged periods or have a sedentary lifestyle are more likely to develop sciatica than active people are.
- Diabetes. This condition, which affects the way your body uses blood sugar, increases your risk of nerve damage.
