Osteoporosis

Osteoporosis occurs when bones become 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.

  • Causes

    Throughout life, old bone is removed and new bone is added to your skeleton. After age 30, more bone is lost than replaced. If too much bone loss occurs, this may lead to osteoporosis. Osteoporosis is more likely to occur if full bone mass was not achieved during your bone-building years.

  • Definition

    Osteoporosis occurs when bones become weak and brittle. If left unchecked, it can lead to Fracture. Any bone can be affected. Fractures of special concern are of the Hip Fracture, Vertebral Compression Fracture and Wrist Fracture.

  • Diagnosis

    Your doctor will ask about your symptoms and medical history. A physical exam will be done. Tests may include:

    • Blood tests
    • Urine tests

    Osteoporosis can be seen with bone mineral density (BMD) tests of the hip, spine, wrist or other site. These may include:

    • Central (preferred) or peripheral dual-energy x-ray absorptiometry (DXA)
    • Quantitative ultrasound (QUS)
    • Central or peripheral quantitative CT scan (QCT)

  • Prevention

    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.

    To help reduce your chance of developing osteoporosis, take these steps:

    • Eat a balanced diet rich in calcium and vitamin D
    • Perform weight-bearing exercise
    • Live a healthy lifestyle (no smoking, drink alcohol only in moderation)
    • If you are a postmenopausal woman at high risk for bone fractures, medications may be appropriate to prevent osteoporosis

  • Risk Factors

    Osteoporosis is more common in women than in men. Other factors that may increase your chance of developing osteoporosis include:

    • Increasing age
    • Low weight
    • Smoking
    • Alcohol abuse
    • History of falls
    • Family history of osteoporosis
    • Postmenopausal status

    Certain conditions, such as:

    • Rheumatoid arthritis
    • Amenorrhea
      (no menstrual periods)
    • Hyperthyroidism
    • Type 2 diabetes
    • Asthma
    • Liver disease
    • Eating disorder
    • Depression
    • Crohn's disease
    • Use of certain medications, such as antidepressants, long-term heparin, corticosteroids, anticonvulsants, or antacids
    • Low hormone levels (low estrogen levels in women, low testosterone levels in men)
    • Inactive lifestyle
    • Certain restrictive diets that may result in a deficit of
      calcium
      or
      vitamin D
    • Too little sunlight (the effect of sun on the skin is a primary source of vitamin D)
    • Certain cancers, including
      lymphoma
      and
      multiple myeloma

  • Symptoms

    In most cases, people with osteoporosis remain symptom-free until there is a fracture. In those that do have symptoms, osteoporosis may cause:

    • Severe back pain with fracture of the vertebrae, wrists, hips, or other bones
    • Loss of height with stooped posture, a condition called kyphosis

  • Treatment

    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.
