What Is Osteoporosis?

Osteoporosis is a condition where bones lose density and become weak and brittle, so they break more easily. It is especially common in women after menopause, when falling estrogen levels speed up bone loss.

Why is osteoporosis more common after menopause?

Estrogen helps keep bones strong. After menopause, estrogen levels fall and bone loss speeds up for several years. Women who reach menopause early, or who have had their ovaries removed, have a higher risk. Other risk factors include a family history of osteoporosis, low body weight, smoking, heavy drinking and long-term use of steroid medicines.

What are the symptoms of osteoporosis?

Osteoporosis usually causes no symptoms until a bone breaks. Fractures of the wrist, hip and spine are the most common. Spinal fractures can lead to back pain, loss of height or a stooped posture. Because of this, the condition is often found only after a minor fall causes a fracture.

How is osteoporosis diagnosed and treated?

A bone density scan (DEXA scan) measures bone strength. Treatment aims to lower the risk of fractures. Depending on the person, a doctor may suggest medicines that strengthen bone, calcium and vitamin D, and for some women hormone replacement therapy.

Can lifestyle help keep bones strong?

Regular weight-bearing and muscle-strengthening exercise, such as walking or strength training in perimenopause, is generally recommended for bone health. A balanced diet, not smoking and limiting alcohol may also help. Ask a doctor before starting new exercise if you already have osteoporosis.
