Age: As we age, our spinal discs lose some of the fluid that helps them maintain flexibility. Wear and tear of the disc is an extension of disc dehydration and the natural progression of aging.
Occupation: People with physically demanding jobs have a greater risk of back problems.
Trauma: Injuries to the spine can cause tiny tears or cracks in the outer layer of the disc.
Weight: Excess body weight places extra stress on the discs of the lower back.
