Osteoporosis is a disease in which bones become fragile and more likely to fracture. Usually the bone loses density, which measures the amount of calcium and minerals in the bone.
Thin bones; Low bone density
Causes, incidence, and risk factors
Osteoporosis is the most common type of bone disease.
Bone is living tissue. Existing bone is constantly being replaced by new bone. Osteoporosis occurs when the body fails to form enough new bone, when too much existing bone is reabsorbed by the body, or both.
Calcium is one of the important minerals needed for bones to form. If you do not get enough calcium and vitamin D, or your body does not absorb enough calcium from your diet, your bones may become brittle and more likely to fracture.
Sometimes bone loss occurs without any cause. Caucasian women are more likely to have bone loss. Sometimes the tendency to have bone loss and thin bones is passed down through families.
A drop in estrogen in women at the time of menopause and a drop in testosterone in men is a leading cause of bone loss. Other causes of bone loss include:
Being confined to a bed
Certain medical conditions
Taking certain medicines
Other risk factors include:
Absence of menstrual periods (amenorrhea) for long periods of time
A family history of osteoporosis
Drinking a large amount of alcohol
Low body weight
Osteoporosis is a rare disease of the bones.The correct answer is myth. Osteoporosis is the most common type of bone disease. People with osteoporosis develop weak bones that can break easily. Finding and treating osteoporosis early before bones become too weak can help prevent breaks.Osteoporosis develops when:The correct answer is both. Even though bones are hard, they are living tissue. The body is constantly building new bone tissue to replace the bone tissue it uses up. If it can’t do this fast enough, the bones become weak and brittle. Aging, too little calcium, or certain health problems can cause bone loss.In the early stages, a common sign of osteoporosis is:The correct answer is none of the above. There are no symptoms in the early stages of osteoporosis. Many times, a bone break is the first sign of the disease. This is why people at risk should be tested for osteoporosis. Ask your doctor about your risk for osteoporosis.Osteoporosis often causes fractures of the:The correct answer is all of the above. About half of all women over the age of 50 will have a fracture of the hip, wrist, or vertebra during their lifetime because of bone loss. Menopause is a good time to talk with your doctor about your risk of osteoporosis and how to reduce it.Osteoporosis can make you shorter.The correct answer is fact. Over time, osteoporosis can cause many small breaks along the spine. These breaks in the vertebrae can gradually cause back pain, stooped posture, and a loss of up to 6 inches of height. Your doctor can detect these breaks with an x-ray of the spine.The best osteoporosis screening measures the amount of bone in the:The correct answer is lower spine and hip. Your doctor uses a type of X-ray machine to test you for osteoporosis. You might see small X-ray machines in pharmacies or at health fairs. They can measure bones in the finger, wrist, leg, or heel, but are not as accurate as the X-ray machine your doctor uses.Which lifestyle change can help prevent and treat osteoporosis?The correct answer is all of the above. Your body needs calcium to build bone. To build strong bones, you should get enough calcium in your diet starting in childhood or early adulthood. Dairy products have the most calcium. Smoking and alcohol use reduces bone strength. Talk with your doctor about how to prevent osteoporosis.Osteoporosis medicines can reduce the risk of fractures.The correct answer is fact. Bisphosphonates (Fosamax, Boniva, Actonel , or Reclast) are used to prevent and treat bone loss. They help make the bones in your hips, spine, and other areas stronger. You may take a pill weekly or monthly or have an IV infusion once a year. Talk with your doctor about the pros and cons of this medicine.Your doctor will prescribe medicine only if you already have osteoporosis.The correct answer is false. Your doctor may also prescribe medicine if you have had a bone fracture and a bone test shows your bones are thinner than normal bones. The goal is to prevent another bone fracture by building up your bones.To reduce the risk of falls, people with osteoporosis should:The correct answer is all of the above. Hip fractures are one of the main reasons people have to go into nursing homes. If you have osteoporosis, and even if you don’t, avoiding falls and fractures can help you stay independent. Talk with your doctor about other ways to prevent falls.
There are no symptoms in the early stages of osteoporosis. Many times, people will have a fracture before learning that they have the disease.
Pain almost anywhere in the spine can be caused by fractures of the bones of the spine. These are called compression fractures. They often occur without an injury. The pain occurs suddenly or slowly over time.
There can be a loss of height (as much as 6 inches) over time. A stooped posture or kyphosis (also called a dowager’s hump) may develop.
Exams and tests
Bone mineral density testing (most often with a DEXA scan) measures your bone mineral density. Your healthcare provider uses this test to:
- Diagnose bone loss and osteoporosis
- Predict your risk of future bone fractures
- See how well osteoporosis medicine is working
You may need other blood and urine tests if your osteoporosis is thought to be due to a medical condition, rather than simply the usual bone loss seen with older age.
Treatment for osteoporosis may involve:
Lifestyle changes, such as diet and exercise
Taking calcium and vitamin D
Medicines are used to strengthen bones when:
- Osteoporosis has been diagnosed by a bone density study, whether or not you have a fracture.
- A bone fracture has occurred and a bone density test shows that you have thin bones, but not osteoporosis.
Medicines used to treat osteoporosis include:
- Bisphosphonates (the main drugs used to prevent and treat osteoporosis in postmenopausal women)
- Estrogens, teriparatide, raloxifene, and calcitonin
Exercise plays a key role in preserving bone density in older adults. Some of the exercises recommended to reduce your chance of a fracture include:
- Weight-bearing exercises — walking, jogging, playing tennis, dancing
- Free weights, weight machines, stretch bands
- Balance exercises — tai chi, yoga
- Rowing machines
Your body needs calcium and vitamin D to keep your bones strong. Vitamin D helps your body absorb calcium.
- Adults under age 50 should have 1,000 mg of calcium and 400 – 800 IU of vitamin D daily.
- Women ages 51 to 70 should have 1,200 mg of calcium and 400 – 800 IU of vitamin D a day; men ages 51 to 70 need 1,000 mg of calcium and 400 – 800 IU of vitamin D a day.
- Adults over age 70 should get 1,200 mg of calcium and 800 IU of vitamin D daily.
- Your doctor may recommend a calcium supplement.
- Follow a diet that provides the proper amount of calcium and vitamin D.
Stop unhealthy habits:
Quit smoking, if you smoke.
Limit your alcohol intake. Too much alcohol can damage your bones. This puts you at risk of falling and breaking a bone.
It is important to prevent falls. The following are suggestions on how to do this:
- Do not take sedating medicines, which can make you drowsy and unsteady. If you must take them, be extra careful when you are up and about. For example, hold on to countertops or sturdy furniture to avoid falling.
- Remove household hazards, such as throw rugs, to reduce the risk of falls.
- Leave lights on at night so you can see better when walking around your house.
- Install and use safety grab bars in the bathroom.
- Make sure your vision is good. Have your eyes checked once or twice a year by an eye doctor.
Wear shoes that fit well and that have heels. This includes slippers. Slippers that do not have heels can cause you to trip and fall.
Do not walk outdoors alone on icy days.
Surgery to treat severe, disabling pain from spinal fractures due to osteoporosis include:
- Spinal fusion
Medicines to treat osteoporosis can help prevent future fractures. But spine bones that have already collapsed cannot be reversed.
Osteoporosis can cause a person to become disabled from weakened bones. Hip fractures are one of the main reasons people are admitted to nursing homes.
Calcium is important for building and maintaining healthy bone. Vitamin D is also needed because it helps your body absorb calcium. Following a healthy, well-balanced diet can help you get these and other important nutrients.
Other tips for prevention:
Medicines can prevent osteoporosis. Your doctor can tell you if any are right for you.
