What causes scoliosis?
We really don’t know the cause of scoliosis. That’s why the most common form if it is called “idiopathic.” That means there is no known reason for the condition. It may be passed on from generation to generation through the genes, but not every person with scoliosis has a family member with scoliosis. As far as we know, carrying a book bag even a really heavy one, even on the same shoulder all the time will not cause scoliosis. There is also no evidence that bad posture causes scoliosis.
