The spine, or backbone, is made up of small bones (vertebrae) stacked -- along with discs -- one on top of another. A healthy spine when viewed from the side has gentle curves to it. The curves help the spine absorb stress from body movement and gravity.
When viewed from the back, the spine should run straight down the middle of the back. When abnormalities of the spine occur, the natural curvatures of the spine are misaligned or exaggerated in certain areas, as occurs with lordosis, kyphosis, and scoliosis.
You can eat a healthy diet, exercise religiously, and follow every single one of your doctor's recommendations -- but no matter how healthy or well-conditioned your body may be, at some point, your lower back is almost destined to cause you problems.
For most people, low back pain is just a minor annoyance that emerges once in awhile, sticks around for a couple of days, then goes away. For other people, there's no break from the pain.

Doctors do not know what causes the most common type of scoliosis seen in adolescents. However, doctors do know that scoliosis tends to run in families. A disease, injury, infection, or birth defect also may be to blame.
