==Overview==
Osteoporosis is the thinning of bone tissue and loss of bone density over time.
[[Osteoporosis]] is the thinning of [[bone]] [[tissue]] and loss of [[bone density]] over time.


==What are the symptoms of Osteoporosis?==
==What are the symptoms of osteoporosis?==
There are no symptoms in the early stages of the disease.
There are no [[symptoms]] in the early stages of the [[disease]]. [[Symptoms]] occurring late in the [[disease]] include:


Symptoms occurring late in the disease include:
* [[Bone pain]] or [[tenderness]]
* [[Fractures]] with little or no [[trauma]]
* Loss of height (as much as 6 inches) over time
* [[Low back pain]] due to [[fractures]] of the [[Vertebrae|spinal bones]]
* [[Neck]] pain due to [[fractures]] of the [[Vertebrae|spinal bones]]
* Stooped [[posture]] or [[kyphosis]], also called a "dowager's hump"


* Bone pain or tenderness
==What causes osteoporosis?==
* Fractures with little or no trauma
* [[Osteoporosis]] is the most common type of [[bone]] [[disease]]. Researchers estimate that about 1 out of 5 American women over the age of 50 have [[osteoporosis]]. About half of all women over the age of 50 will have a [[fracture]] of the [[hip]], [[wrist]], or [[vertebra]] (bones of the [[spine]]). [[Osteoporosis]] occurs when the body fails to form enough new [[bone]], when too much old [[bone]] is reabsorbed by the body or both.
* Loss of height (as much as 6 inches) over time* Low back pain due to fractures of the spinal bones
* Neck pain due to fractures of the spinal bones
* Stooped posture or kyphosis, also called a "dowager's hump"


==What causes Osteoporosis?==
* [[Calcium]] and [[phosphate]] are two [[minerals]] that are essential for normal [[bone]] formation. Throughout youth, your body uses these [[minerals]] to produce [[bones]]. If you do not get enough [[calcium]], or if your [[body]] does not absorb enough [[calcium]] from the [[diet]], [[bone]] production and [[bone]] [[tissues]] may suffer.
Osteoporosis is the most common type of bone disease. Researchers estimate that about 1 out of 5 American women over the age of 50 have osteoporosis. About half of all women over the age of 50 will have a fracture of the hip, wrist, or vertebra (bones of the spine). Osteoporosis occurs when the body fails to form enough new bone, when too much old bone is reabsorbed by the body, or both.


Calcium and phosphate are two minerals that are essential for normal bone formation. Throughout youth, your body uses these minerals to produce bones. If you do not get enough calcium, or if your body does not absorb enough calcium from the diet, bone production and bone tissues may suffer.
* As you age, [[calcium]] and [[phosphate]] may be reabsorbed back into the body from the [[bones]], which makes the [[bone]] tissue weaker. This can result in brittle, fragile [[bones]] that are more prone to [[fractures]], even without [[injury]]. Usually, the loss occurs gradually over years. Many times, a person will have a [[fracture]] before becoming aware that the [[disease]] is present. By the time a [[fracture]] occurs, the [[disease]] is in its advanced stages and damage is severe. The leading causes of [[osteoporosis]] are a drop in [[estrogen]] in women at the time of [[menopause]] and a drop in [[testosterone]] in men. Women over age 50 and men over age 70 have a higher risk for [[osteoporosis]].

* Other causes include:
 
** Being confined to a bed
Other causes include:
** Chronic [[rheumatoid arthritis]], [[chronic kidney disease]], [[eating disorders]]
 
** Taking [[corticosteroid]] medications ([[prednisone]], [[methylprednisolone]]) every day for more than 3 months, or taking some [[Anticonvulsant|antiseizure]] drugs

White women, especially those with a family history of osteoporosis, have a greater than average risk of developing osteoporosis. Other risk factors include:
 
* Absence of menstrual periods (amenorrhea) for long periods of time
* Drinking a large amount of alcohol
* Family history of osteoporosis
* History of hormone treatment for prostate cancer or breast cancer
* Low body weight
* Smoking
* Too little calcium in the diet

==Treatment options==
==Treatment options==
The goals of osteoporosis treatment are to:
There are several different treatments for [[osteoporosis]], including lifestyle changes and a variety of medications. The goals of [[osteoporosis]] treatment are to:
 
* Control pain from the disease
* Slow down or stop bone loss
* Prevent bone fractures with medicines that strengthen bone
* Minimize the risk of falls that might cause fractures
 
There are several different treatments for osteoporosis, including lifestyle changes and a variety of medications.
 
Medications are used to strengthen bones when:


Osteoporosis has been diagnosed by a bone density study.
* Control [[pain]] from the [[disease]]
Osteopenia (thin bones, but not osteoporosis) has been diagnosed by a bone density study, if a bone fracture has occurred.
* Slow down or stop [[bone loss]]
* Prevent [[bone fractures]] with medicines that strengthen [[bone]]
* Minimize the risk of falls that might cause [[fractures]]


BISPHOSPHONATES
[[Medications]] are used to strengthen [[bones]] when:
* Bisphosphonates are the primary drugs used to both prevent and treat osteoporosis in postmenopausal women.
* Bisphosphonates taken by mouth include alendronate (Fosamax), ibandronate (Boniva), and risedronate (Actonel). Most are taken by mouth, usually once a week or once a month.
* Bisphosphonates given through a vein (intravenously) are taken less often.


CALCITONIN
* [[Osteoporosis]] has been diagnosed by a [[bone density]] study.
* [[Osteopenia]] (thin [[bones]], but not [[osteoporosis]]) has been diagnosed by a [[bone density]] study, if a bone [[fracture]] has occurred.


* Calcitonin is a medicine that slows the rate of bone loss and relieves bone pain. It comes as a nasal spray or injection. The main side effects are nasal irritation from the spray form and nausea from the injectable form.

* Estrogens or hormone replacement therapy (HRT) is rarely used anymore to prevent osteoporosis and are not approved to treat a woman who has already been diagnosed with the condition.
''HORMONE REPLACEMENT THERAPY''
* Sometimes, if estrogen has helped a woman, and she cannot take other options for preventing or treating osteoporosis, the doctor may recommend that she continue using hormone therapy. If you are considering taking hormone therapy to prevent osteoporosis, discuss the risks with your doctor.

Overview

Osteoporosis is the thinning of bone tissue and loss of bone density over time.

What are the symptoms of osteoporosis?

There are no symptoms in the early stages of the disease. Symptoms occurring late in the disease include:

What causes osteoporosis?

  • As you age, calcium and phosphate may be reabsorbed back into the body from the bones, which makes the bone tissue weaker. This can result in brittle, fragile bones that are more prone to fractures, even without injury. Usually, the loss occurs gradually over years. Many times, a person will have a fracture before becoming aware that the disease is present. By the time a fracture occurs, the disease is in its advanced stages and damage is severe. The leading causes of osteoporosis are a drop in estrogen in women at the time of menopause and a drop in testosterone in men. Women over age 50 and men over age 70 have a higher risk for osteoporosis.

Treatment options

There are several different treatments for osteoporosis, including lifestyle changes and a variety of medications. The goals of osteoporosis treatment are to:

Medications are used to strengthen bones when:

BISPHOSPHONATES

CALCITONIN

HORMONE REPLACEMENT THERAPY

PARATHYROID HORMONE

  • Teriparatide (Forteo) is approved for the treatment of postmenopausal women who have severe osteoporosis and are considered at high risk for fractures. The medicine is given through daily shots underneath the skin. You can give yourself the shots at home.

RALOXIFENE

EXERCISE

Regular exercise can reduce the likelihood of bone fractures in people with osteoporosis. Some of the recommended exercises include:

  • Weight-bearing exercises -- walking, jogging, playing tennis, dancing
  • Resistance exercises -- free weights, weight machines, stretch bands
  • Balance exercises -- Tai chi, yoga
  • Riding a stationary bicycle
  • Using rowing machines
  • Avoid any exercise that presents a risk of falling, or high-impact exercises that may cause fractures.

DIET

Get at least 1,200 milligrams per day of calcium and 800 - 1,000 international units of vitamin D3. Vitamin D helps your body absorb calcium. Your doctor may recommend a supplement to give you the calcium and vitamin D you need. Follow a diet that provides the proper amount of calcium, vitamin D, and protein. While this will not completely stop bone loss, it will guarantee that a supply of the materials the body uses to form and maintain bones is available.

High-calcium foods include:

  • Cheese
  • Ice cream
  • Leafy green vegetables, such as spinach and collard greens
  • Low-fat milk
  • Salmon
  • Sardines (with the bones)
  • Tofu
  • Yogurt

STOP UNHEALTHY HABITS

Quit smoking, if you smoke. Also, limit alcohol intake. Too much alcohol can damage your bones, as well as put you at risk for falling and breaking a bone.

PREVENT FALLS

It is critical to prevent falls. Avoid sedating medications and remove household hazards to reduce the risk of fractures. Make sure your vision is good. Other ways to prevent falling include:

  • Avoiding walking alone on icy days
  • Using bars in the bathtub, when needed
  • Wearing well-fitting shoes

MONITORING

Your response to treatment can be monitored with a series of bone mineral density measurements taken every 1 - 2 years. Women taking estrogen should have routine mammograms, pelvic exams, and Pap smears.

RELATED SURGERIES

What to expect (outlook/prognosis)?

Medications to treat osteoporosis can help prevent fractures, but vertebrae that have already collapsed cannot be reversed. Some persons with osteoporosis become severely disabled as a result of weakened bones. Hip fractures leave about half of the patients unable to walk independently. This is one of the major reasons people are admitted to nursing homes. Although osteoporosis is debilitating, it does not affect life expectancy.
