Height loss is a symptom of osteoporosis. This is observed more frequently with advancing age wherein height loss to the extent of 4 cm or more is experienced.
The vertebrae looses bone mass due to brittle nature(reduced bone density) and hence a reduction in height occurs. This is visible in the form of a “rounded back” ("dowager’s hump") with associated pain in the back spine. This stage of advanced osteoporosis is accompanied by vulnerability to bone fracture from minor falls and supportive usage to save a fall.
