Osteoporosis
Osteoporosis is a condition in which bones gradually lose density and strength, becoming fragile and more likely to fracture. It often develops silently over many years, with no symptoms until a bone breaks. Common fracture sites include the hip, wrist and spine. It is most common in older adults, especially women after menopause.
Overview
What is osteoporosis?
Osteoporosis means porous bones. Bone is living tissue that constantly renews itself, but in osteoporosis bone is lost faster than it is replaced. This makes the internal structure of the bone thinner and weaker, so bones become fragile and can break more easily, sometimes after a minor fall or even everyday movements.
How common is osteoporosis and who does it affect?
Osteoporosis is common, particularly among older people, and affects many millions worldwide. Women are affected more often than men, especially after menopause when protective hormone levels fall. Risk rises steadily with age in both sexes. Because it often causes no symptoms, many people only learn they have it after breaking a bone.
Symptoms and Causes
What are the symptoms of osteoporosis?
Osteoporosis itself usually causes no symptoms in its early stages, which is why it is sometimes called a silent condition. It is often first noticed when a bone breaks unexpectedly. Over time, fractures in the spine can lead to back pain, loss of height or a stooped posture. A broken bone may be the first warning sign.
What causes osteoporosis and who is at risk?
Bone density naturally declines with age, and osteoporosis develops when this loss becomes significant. Risk factors include older age, being female and post-menopausal, a family history of the condition, low body weight, smoking, heavy alcohol use and a lack of physical activity. Some medical conditions and long-term use of certain medicines can also weaken bones.
Diagnosis and Tests
How is osteoporosis diagnosed?
Osteoporosis is most often diagnosed using a bone density scan, commonly a DXA scan, which measures the strength of the bones, usually at the hip and spine. A doctor may also assess your overall risk of fracture by considering factors such as age, medical history and previous broken bones. Blood tests sometimes help identify underlying causes.
Management and Treatment
How is osteoporosis treated or managed?
Treatment aims to strengthen bones and prevent fractures. This often combines lifestyle measures, such as regular weight-bearing exercise, adequate calcium and vitamin D, stopping smoking and limiting alcohol. Doctors may also prescribe medication to slow bone loss or support bone formation. Reducing the risk of falls, for example by improving balance and home safety, is also important.
Prevention
Can osteoporosis be prevented or its risk reduced?
Building and protecting bone health throughout life lowers the risk. Helpful steps include regular weight-bearing and muscle-strengthening exercise, eating a balanced diet with enough calcium and vitamin D, not smoking and keeping alcohol within sensible limits. Preventing falls becomes especially important with age. Discussing your personal risk with a doctor can guide further prevention.
Additional Common Questions
Is osteoporosis a normal part of getting older?
Some bone loss is normal with age, but osteoporosis is more than that. It involves significant weakening that raises fracture risk, and there are steps that can help slow or manage it.
Can men get osteoporosis?
Yes. Although it is more common in women, men can also develop osteoporosis, particularly at older ages or with certain health conditions and risk factors.
Is osteoporosis painful?
Osteoporosis itself is usually not painful. Pain typically arises only when a bone breaks, such as a fracture in the spine, hip or wrist.
