Disk problems are sometimes lumped together under the term degenerative disk disease.
The disks that separate your vertebrae wear down. This sometimes causes the bones to rub together. Age is usually the reason, but sports and injuries can be culprits, too.
Change in the condition of the disk is a natural result of aging. This is part of our slow loss of flexibility as we grow older.
But disk degeneration is far more serious in some people than in others. Severe cases may be the result of a deficiency in collagen, the material that makes up cartilage.
Poor muscle tone, poor posture, and obesity also put extra strain on the spine and the ligaments that hold the disks in place.
