Herniated Disk | Causes & Risk Factors


How does a disk become herniated?

As you grow older, the disks in your spine weaken and become flatter -- less cushiony. If a disk becomes too weak, the outer part may tear. The inside part of the disk then pushes through the tear and presses on the nerves beside it. Herniated disks are most common in people in their 30s and 40s.
