Sciatica Causes & Risks

Causes

Anything that causes irritation or puts pressure on the sciatic nerve can cause sciatica, including:

  • Herniated disk (or slipped disk)—the cushions between the bones of your spine bulge out of place and press on the nerve as it exits the spinal column
  • Disk degeneration—caused by aging or arthritis
  • Spinal stenosis —narrowing of the spinal canal in the lumbar area
  • Spondylolisthesis —slippage of a bone in the low back
  • Sprain or strain of muscles or ligaments in the area
  • In rare cases:
    • Benign or malignant tumors
    • Infections
    • Blood clots
    • Metabolic problems like diabetes
    • Toxins, such as excessive alcohol

Risk Factors

These factors increase your chance of developing sciatica. Tell your doctor if you have any of these risk factors:

  • Age: 25-45 years old
  • Injury, such as:
    • Lifting a heavy object
    • Suddenly moving or twisting
  • Family members with sciatica or low back problems
  • Vibration from vehicles or heavy equipment
  • Lack of regular exercise
  • Obesity
  • Smoking
  • Stress
