What causes Intervertebral disc disease ?
What causes intervertebral disc disease? Intervertebral disc disease (IDD) is a multifactorial disorder, which means that both genetic and environmental factors probably interact to predispose an individual to the condition. It is likely that several factors are needed for development of IDD. Factors such as occupational stress, trauma, or obesity, together with genetic alterations, may result in the structural weakness of a disc, cause a herniation, and possibly initiate a cascade of events leading to sciatica and pathological disc changes. One of the best-known environmental risk factors for IDD is vibration in occupational driving. Inflammation is also likely to play an important role in the progression of this process.
