Osteoporosis and you
Osteoporosis (aa·stee·ow·pr·ow·suhs) literally means "porous bone." The bones become weak as a result of the body losing too much or not creating enough bone.
Unfortunately, weak, thin bones tend to break, and most people with Osteoporosis have no symptoms until they break a bone.
It is estimated that about 10 million Americans suffer from Osteoporosis, and an additional 44 million are at risk for developing it.
Women are two times more likely than men to develop Osteoporosis. Their risk significantly increases in their 50s primarily due to menopause. Half of all women will break a bone in their lifetime due to Osteoporosis.
Weak bones can increase an older person's risk of falling, see the GeriAcademy post Don't Let Falls Get You Down. Think of your bones the way you would the foundation of a house, which bears the entire house's weight, and in this case, your home is your body.
Both women and men build bone at about the same rate and have the most robust bones into their mid-twenties, after which the rate of bone loss changes for women and men.
In Women
From the mid '30s-'40s, bones are generally stable, there is slow bone loss. Around the mid-40s-50s, women start to experience more rapid bone loss, especially during menopause; they can lose about 7% per year. By the mid-50s to late life, women will continue to lose 1-2% of bone yearly.
In Men
After age 30, there is about a 1% bone loss per year, but can lose up to 6% of bone yearly depending on risk factors.
Geriatricians fear Osteoporosis, and they fear falls!
Bone fractures are the most common condition requiring hospitalization for individuals 65 years and older. Some studies estimate that about 1.5 million people annually suffer a bone fracture related to bone disease. Hip, spine, and forearm fractures are the most commonly seen in older adults.
About 20% of older adults who sustain a hip fracture die within the first year, and up to 50% never return to their previous functioning level.
Are you at risk for Osteoporosis?
When it comes to Osteoporosis, some risk factors can be reduced, and some cannot!
Risk factors that can be changed
Poor Nutrition
Little to no physical activity
Rapid unintentional weight loss, or weight less than 127 pounds
Cigarette smoking
Excessive use of alcohol
Air pollution
Stress
Risk Factors that cannot be changed
Older age
Female
White ethnic background
Previous bone break
Family history of Osteoporosis
History of falls
Other Risk factors
Thyroid disease
Chronic liver disease
Hypogonadism- a condition where the body doesn't produce hormones like testosterone.
Chronic steroid use
Vitamin D deficiency
Heart disease
Diabetes mellitus
Dementia
Chronic kidney disease
Rheumatoid arthritis and other inflammatory diseases
Should I get tested for Osteoporosis?
The recommendation is that every woman over the age of 65 should be tested. For men, there is no routine testing.
Additionally, any older adult with the risk factors described above or loss of height by more than 1.5 inches should be tested, regardless of gender.
How do I get tested for Osteoporosis?
The most common test to detect Osteoporosis is called a DEXA scan (dual-energy X-ray absorptiometry). Basically, an x-ray, looking at bone thickness. The spine, hips, and wrists are common test sites. This test is usually repeated every 2 years. Medicare generally covers testing for those that qualify.
Suppose you have already had a fall and sustained a fracture. In that case, you are considered to have the diagnosis of Osteoporosis even without a DEXA scan. You may need to receive treatment to prevent a future fracture. Unfortunately, less than 10% of patients who should be receiving treatment for Osteoporosis after a fracture do so.
Sometimes the result of a bone scan is osteopenia. Osteopenia is low bone composition, not Osteoporosis. It means you are at greater risk of developing Osteoporosis and need to work harder to prevent disease development. It is important that you discuss osteopenia treatment with your health care provider to prevent Osteoporosis.
Preventing Osteoporosis
Start by tackling the risk factors that can be modified. For example, try to quit smoking, decrease alcohol intake, start getting active.
Next, ensure you are taking enough vitamin D and Calcium. The FDA recommends that older adults take 800 units of vitamin D3 daily. Vitamin D has been shown to maintain bone health and prevent falls in older adults. When Vitamin D is combined with Calcium it has been shown to reduce the risk of fracture.
A daily Vitamin D supplement at the recommended dose is safe to take. Additionally, foods that contain Vitamin D include Milk, yogurt, sardines, tuna, leafy greens, beans, liver, eggs, and certain mushrooms.
The daily recommended dose of Calcium is about 1200 mg. This includes the Calcium you eat in your diet, and take as a pill. Keep in mind if you eat enough calcium-rich foods, you should not take an additional supplement. See the table below.
Too much Calcium is not safe, check out the the GeriAcademy blog on Vitamins and Herbs which discusses safety of Calcium and Vitamin D.
For example, if you eat a cup of yogurt and drink a glass of milk daily, then you would need an additional 500-600 mg of Calcium that day. This could include taking a supplement, or other foods that contain Calcium.
What if I have Osteoporosis? What are some treatment options?
There are two types of Osteoporosis medications. One type prevents bones from breaking down, and the other helps the body build bones. Some of these medications can be taken by mouth, injected with varying frequency including daily, monthly to yearly. It is crucial to talk to your health care provider about what type of treatment is best for you.
Treatments for Osteoporosis, just like all other medicines, have side effects but are generally well-tolerated. It is crucial to have an evaluation for treatment options.
Getting active!
Exercise helps to prevent and treat Osteoporosis by strengthening bones and the muscles that support your bones. The best type of exercise includes a combination of strength, balance and flexibility. The National Institute on Aging has a free book that can be downloaded through the their site called Workout to Go. Consult with your primary care provider before starting any exercise program to prevent hurting yourself.
