How Do You Get a Bulging Disc?

Causes of a bulging disc include aging, contact sports, incorrect lifting techniques, severe trauma, and a family history of the condition, states the Laser Spine Institute. Smoking, excessive alcohol consumption and jobs that feature large amounts of repetitive movements are also causes.

The neck and lower back are the most frequent sites for a bulging disc, explains the Laser Spine Institute. It is less common for a bulging disc to occur in the mid-back section. Discs lose water content as they age, making them less elastic and more prone to damage. When a bulging disc ruptures, the inner cartilage leaks out and results in a herniated disc. Bulging discs become more common as an individual reaches his 30s and 40s.
