Osteoporosis is a disease marked by decreasing bone mass, density, and quality, making bones weak and brittle. If left unchecked, it can lead to fractures. Any bone can be affected. Fractures of special concern are of the hip, spine, and wrist.

Osteoporosis is caused by an imbalance between bone loss and bone formation (known as bone remodeling). After age 30, bone loss occurs more quickly. Many factors over the course of a lifetime can influence bone remodeling.
Osteoporosis is more common in older adults. It is more common in women than in men. People of Caucasian, Asian, or Hispanic ethnicity are more likely to get osteoporosis.
Osteoporosis is more likely to occur if full bone mass was not achieved during your bone-building years. Other factors that may increase your chance of osteoporosis include:
In most cases, people with osteoporosis remain symptom-free until there is a fracture. In those who do have symptoms, osteoporosis may cause:

You will be asked about your symptoms and medical history. A physical exam will be done. Tests may include:
The density level of your bones may be tested. This can be done with:
The treatment and management of osteoporosis involves lifestyle changes and medications. Although osteoporosis is highly preventable, it cannot be cured. Treatment focuses on reducing the incidence of fractures and slowing bone loss.
Decrease your intake of alcohol. Eat a balanced diet rich in calcium and vitamin D. Calcium is in:
Do not smoke. If you smoke, talk with your doctor about ways you can successfully quit.
Exercise improves bone health. It also increases muscle strength, coordination, and balance. Do weight-bearing and strength-training exercises for maximum benefit. Balance training may help prevent falls and fractures.
People who do not eat enough calcium from food might want to take calcium supplements. Vitamin D and other supplements may also be advised. Talk with your doctor before taking herbs or supplements.
Falls can increase the chance of fracture in someone with osteoporosis. Here are ways to prevent falls:
Certain medications can help prevent bone loss, increase bone density, and reduce your risk of fractures. These may include:
Building strong bones throughout your early years is the best defense against osteoporosis. Getting enough calcium, vitamin D, and regular exercise can keep bones strong throughout life.
