The clinical symptoms of osteoporosis, in mild cases, may result in no discomfort at all. As the condition worsens gradually, pain may surface in the lumbar and back areas, or even aches throughout the body. This commonly intensifies after physical exertion or activity, leading to a decline in weight-bearing capability, or even an inability to bear weight.

The second symptom is a reduction in height and shrinking stature, commonly due to vertebral compression fractures, which can be solitary or multiple, occurring with or without a specific cause.

The third symptom involves fragile fractures, which can occur from minimal activities or traumas, like bending, bearing weight, compression, or falling. These are commonly known as brittle fractures, which are clinical manifestations of osteoporosis.
