Osteoporosis is a condition that is characterized by the weakening of bones. The bones become so brittle that even a mild strain can cause a fracture. This happens because the new bone tissues are not regenerating fast enough to replace the old tissues. The exact cause behind this has yet to be discovered. However, several early warning signs indicate susceptibility to osteoporosis, especially among women. These help in timely diagnosis and treatment.  Low bone density Low bone density means that the mineral density in your bones has declined. Due to this, the body cannot generate new bone at the same rate as it absorbs the old bone. This condition is called osteopenia. Although being diagnosed with osteopenia doesn’t indicate osteoporosis, it is one of the early warning signs. This is because low bone density often precedes severe osteoporosis. If you have been diagnosed with osteopenia, consult your primary care doctor for regular tests and examinations to prevent further bone loss. Brittle bones Another tell-tale early warning sign of osteoporosis is brittle bones. Therefore, there is a higher risk of breaking a bone. These fractures usually occur in the wrist, spine, and hips. However, fractures can occur in any part of the body.
