Kyphosis is curvature of the spine that causes the top of the back to appear more rounded than normal. Everyone has some degree of curvature in their spine. However, a curve of more than 45 degrees is considered excessive. Sometimes kyphosis doesn't cause any symptoms other than the back appearing abnormally curved or hunched. However, in some cases the condition may cause back pain, stiffness, tenderness of the spine, and tiredness.
Back pain can be particularly problematic in adults with kyphosis because the body has to compensate for the spinal abnormality. If you have severe kyphosis, your symptoms may get worse over time. You may also have difficulty breathing and eating.
Kyphosis may develop, among other causes, because of spinal injuries, such as vertebral fractures caused by osteoporosis. Exercise may help by strengthening the muscles in the back. Ask your doctor which exercises may be appropriate for you.
