A slipped disc occurs when the outer ring becomes weak or torn and allows the inner portion to slip out. This can happen with age. Certain motions may also cause a slipped disc. A disc can slip out of place while you are twisting or turning to lift an object. Lifting a very large, heavy object can place great strain on the lower back, resulting in a slipped disc. If you have a very physically demanding job that requires a lot of lifting, you may be at increased risk for slipped discs.

Overweight individuals are also at increased risk for a slipped disc because their discs must support the additional weight. Weak muscles and a sedentary lifestyle may also contribute to the development of a slipped disc.
