Complications

While most people with scoliosis have a mild form of the disorder, scoliosis may sometimes cause complications, including:

• Breathing problems. In severe scoliosis, the rib cage may press against the lungs, making it more difficult to breathe.
• Back problems. People who had scoliosis as children may be more likely to have chronic back pain as adults, especially if their abnormal curves are large and untreated.
• Appearance. As scoliosis worsens, it can cause more noticeable changes — including uneven hips and shoulders, prominent ribs, and a shift of the waist and trunk to the side. Individuals with scoliosis often become self-conscious about their appearance.
