Osteoporosis is a syndrome that affects the density of bones, thereby making them brittle and prone to breakage. Osteoporosis can be caused by a number of different diseases and bodily changes. The most common reason for this syndrome is menopause, which explain why osteoporosis is far more common among elderly women than any other population group. Severe cases of osteoporosis are often caused by genetic defects.
In some extreme cases osteoporosis is life threatening, and limits those that suffer by it to a life in wheelchair. When the condition is this bad, spinal disorders are common, as the bone of the spine is no longer able to withstand the weight of the torso and head.
