Some risk factors can impact the likelihood of getting sciatica, including, but not limited to age, obesity, diabetes, and prolonged periods of sitting.
The best ways to prevent getting sciatica is to exercise on a regular basis, use proper body movements (especially when lifting heavy loads), and maintain good posture as you sit. You can also improve your spinal health by being under regular chiropractic care to ensure no nerves are being pinched in your back and neck.
