Osteoporosis is also known as the silent disease, since you may not know that you have it until you fall and break a bone. Symptoms of osteoporosis usually don't become visable until the disease becomes quite advanced.

Symptoms occur late in the disease and they are:

- Loss of height as a result of weakened spines. A person may find that his/her clothes are no longer fitting and their pants looking longer. Patients may loose as much as 6 inches in height.

- Cramps in the legs at night

- Bone pain and tenderness

- Neck pain, discomfort in the neck other than from injury or trauma

- Persistent pain in the spine or muscles of the lower back

- Abdominal pain

- Tooth loss

- Rib pain

- Broken bones

- Spinal deformities become evident like stooped posture, an outward curve at the top of the spine as a result of developing a vertebral collapse on the back.

- Fatigue

- Periodontal disease

- Brittle fingernails

In osteoporosis, sometimes there may be no symptoms. When present the most important symptom is pain which may be felt in various parts of the body particularly over the skeleton & this is worst with jerking, flexing the spine etc. The findings actually develop when the gradual progress in loss of bone causes a fracture of a bone. There may be acute pain also. Multiple fractures may also develop. Otherwise the usual findings are a loss of height, a stooped posture and a "humpbacked" appearance. There may be gross kyphosis of the vertebrae & later on the thoracic cage is shrunken. This may result in the formation of characteristic transverse skin crease across the upper abdomen which may be keratinized.
