Kyphosis, or roundback posture, refers to an increased curvature of the spine from front to back. It has known causes, and can become progressively worse with time. Kyphosis is more common in women. It is often feared, since it causes a loss of height and poor posture. Severe khyposis is associated with health impairments that include pain, neurological problems, digestive problems, or even difficulty breathing.
