Rethinking osteoporosis
Drug treatments for osteoporosis and osteopenia: Do you really need them?
by Dr. Susan E. Brown, PhD
If you’ve turned on the TV lately, leafed through a magazine, or surfed the internet,
you’ve likely seen an advertisement warning you about bone loss and osteoporosis
risk. And the ad most likely recommends a certain medication to prevent it. It’s
true that more people are being diagnosed with osteoporosis today than in the past,
but many people want to know if they really need to take Boniva, Forteo, Prolia,
or some other prescription medication to strengthen their bones.
For the vast majority of people, my answer would be “no.” I don’t want to give the
impression that I think these drugs should never be used, because there are circumstances
where they’re appropriate — but for most osteoporosis cases, taking a prescription
medication is not needed (and for most people with osteopenia, I don’t think medication
is needed at all!). Osteoporosis and osteopenia medications are big business, but
despite all the hype and marketing from drug companies, there is a safer, more effective
and natural approach to bone health available to you.
How should osteoporosis be treated?
My basic philosophy is that we should work with Nature and with the body’s own healing
capabilities. Osteoporosis happens for a reason, and it’s important for us to find
that reason and correct it if we’re to stop bone loss. For a great many people,
the first place to look for the culprit causing bone loss are these five factors:
- Inadequate nutrition, which can cause the body to tap into the bones to retrieve
needed minerals, particularly calcium
- An acid-forming diet, which triggers the body to call for the release of buffering
mineral compounds from the bones — mainly calcium again
- Chronic stress, which similarly increases the body’s acid load (and keep in mind,
this can be physiologic stress — as occurs during the menopause transition for women
— as well as emotional or mental stress)
- Lack of weight-bearing exercise, which the bones need to trigger activity in bone-building
osteoblasts
- Low levels of specific nutrients, such as vitamin D, vitamin K2, magnesium and manganese,
all of which are central to bone formation.
It’s also important to look for pathological causes, as a great many diseases and
disorders can contribute to bone loss (my article on
Rethinking “primary” osteoporosis discusses these causes in much greater
detail.)
And I’m not alone in this thinking — the Surgeon General of the United States issued treatment
guidelines in 2004 that stated that improvements to dietary and exercise
habits, followed by investigation of potential causes of bone loss, were the first
two steps a physician should recommend to any patient with osteoporosis and osteopenia.
Unfortunately, these guidelines are infrequently followed — it’s simply a whole
lot easier to prescribe a medication than to motivate a patient to change some very
basic lifestyle factors. But in taking the easier path, physicians who bypass the
Surgeon General’s recommendations (assuming they’re even aware of them) are offering
patients a sledgehammer to pound in a screw — when a screwdriver would do the job
better, and with less overall damage!
What are the effects of popular bone drugs?
Here’s the problem. Bone drugs, just like all drugs, have side effects. They aren’t
targeted just at bone — they affect other tissues as well. And sometimes, they affect
these other tissues in ways that are quite worrisome and harmful, particularly when
taken for long periods of time. Here are just two examples:
- Bisphosphonate drugs, which have been prescribed for many years, halt bone breakdown
in the short term, but after about a year they also halt bone building as well,
leading to brittle bones that may be more susceptible to fracture, not
less. We’ve learned that just because bones may look denser on a bone scan, it doesn’t
necessarily mean they are stronger. At the same time, bisphosphonates promote acid
reflux and related esophageal problems, possibly including esophageal cancer.
- Denosumab (Prolia), targets the RANK ligand, a protein that is crucial to the development
of osteoclast cells. Without it, these cells don’t develop, so it reduces bone resorption
— but RANKL is also expressed by cells in the gut epithelium and by T-cells, which
are important immune system cells. Prolia can’t distinguish between RANKL in bone
versus RANKL on a T-cell or epithelial cell — so what happens when it’s suppressed
throughout the body? (Right now, no one knows the answer to that — the drug is still
too new.)
My point in highlighting these examples is that if you’re trying to address an imbalance
in bones, it seems sensible to do so without creating even greater imbalances in
the body. (In the table below, I give a short summary of the best-known bone drugs
on the market today.)
Drug
|
What it does
|
Side effects
|
Concerns with long-term use
|
|
Bisphosphonates
|
|
alendronate (Fosamax), risedronate (Actonel), ibandronate (Boniva), zoledronate
(Zometa / Reclast), pamidronate (Aredia), etidronate (Didronel)
|
All bisphosphonate drugs affect the formation and survival of osteoclasts, the cells
that break down bone, thus reducing bone breakdown activities. The drug molecules
also attach to mineral surfaces in cortical and trabecular bone to increase mass
|
Stomach irritation, esophageal erosion, bone, joint, or muscle pain, atrial fibrillation
(in women), osteonecrosis of the jaw
|
Heightened risk of esophageal cancer; oversuppression of bone turnover leading to
brittle bones and unusual shaft fractures of the femur
|
|
Selective estrogen receptor modulators (SERMs)
|
|
tamoxifen (Nolvadex), raloxifene (Evista) (others in this class are in development
but not yet approved)
|
Binds to estrogen receptors in bone tissue to decrease the activity of osteoclasts;
also reduces the risk of invasive breast cancer. Note that both drugs are only used
for postmenopausal women and not men or premenopausal women. Tamoxifen is not FDA
approved for osteoporosis.
|
Tamoxifen: blood clots, resumption of bone loss after discontinuing
use of the drug. May increase risk of hip fracture in low doses.
Raloxifene: Blood clots in veins, eyes, and lungs, strokes, hot
flashes, leg cramps, leg swelling, shortness of breath, vision changes
|
Increased risk of venous thromboembolism and fatal stroke (more so with tamoxifen
than raloxifene). Tamoxifen's benefit for reducing fractures is maintained only
while the drug is in use.
|
|
Biologics
|
|
Teriparatide (Forteo)
|
Utilizes a segment of human parathyroid hormone to mobilize osteoblast activity
and thereby increase bone formation. Used in men and women at high risk of fracture.
|
Nausea, vomiting, constipation, low energy, muscle weakness, joint aches, leg cramps,
dizziness, increased blood calcium
|
Possible increase in adrenal hormone release after >1 year of use; potential increased
risk of osteosarcoma. Should not be used in persons with Paget's disease of bone,
bone cancer, high blood calcium, or who have had kidney stones or radiation therapy.
|
|
Denosumab (Prolia)
|
Inhibits maturation of osteoclasts by binding to RANKL, a protein that is expressed
by osteoclast precursors.
|
Low blood calcium levels, serious urinary and respiratory tract infections, skin
rashes or inflammation, joint pain, osteonecrosis of the jaw
|
Possible slight increase to risk of cancer. Hypothetical risk to gut and immune
system function, since RANKL also is expressed by T helper cells and controls differentiation
of microfold cells in the intestinal epithelium.
|
|
Calcitonin (Miacalcin)
|
Binds to osteoclasts and inhibits bone resorption; delivered in both injectable
and nasal spray forms
|
Nausea, vomiting, flushing (occurring more often with subcutaneous or intramuscular
delivery than with nasal delivery), dry mouth, headache, joint or back pain, potential
for allergic reaction
|
Few long term effects, but the drug also has only weak effects in building bone.
|
|
PTH-related peptide (PTHrP)
|
When administered as single dose intermittently, markedly increases BMD without
causing hypercalcemia
|
Nausea, vomiting, altered hemodynamics, flushing, hypercalcemia. High doses activate
1,25 dihydroxyvitamin D production.
|
Best known as secretion of certain cancers that produces severe hypercalcemia (high
calcium levels in the blood) and bone resorption.
|
|
Other (drugs not approved for use in the US by the FDA)
|
|
Tibolone (Livial)
|
Mimics the action of estrogen to help preserve bone; inhibits bone resorption
|
Endometrial bleeding, increase in LDL cholesterol in postmenopausal women, increased
risk of stroke
|
Doubles the risk of stroke in postmenopausal women within the first year and in
women over 70. Effects of tibolone on endometrial morphology are as yet unknown.
A possible association with increased risk of breast cancer recurrence has been
noted.
|
|
Strontium ranelate (Protelos)
|
Increases osteoblast replication, differentiation, and activity while decreasing
osteoclast differentiation and activity.
|
Nausea, diarrhea, headache, dermatitis, eczema
|
Possible slight increased risk of venous thromboembolism; rarely, DRESS syndrome
has been observed in patients using this drug.
|
|
Ipriflavone
|
Not found to be effective in preventing bone loss or reducing bone resorption
|
Can suppress white blood cells in a significant number of users.
|
Low white blood cell counts increases risk of infection and serious complications.
|
I understand that some people may need medication for serious bone disorders. What
I often tell my clients is “You want to pull the parachute if you are falling out
of the airplane, but it isn’t a great idea to pull the parachute if you are still
inside the airplane.” My point is than you should only use bone drugs only when
necessary. If you’re concerned about falling off a six-inch log, what makes sense
is a pillow, not a parachute! So for those who are in otherwise good health but
have experienced bone loss because of menopause, vitamin D deficiency, or for some
other reason, it’s worth taking the time to figure out what you really need to cushion
your fall before you decide to grab that parachute.
What you can do to promote natural bone health
I would also argue that it doesn’t hurt to have a pillow along with your
parachute. So even if you make the decision to take medication for your bones, please
try to incorporate my Better Bones Program along with your prescription.
Look closely at your risk. Have an honest discussion with your healthcare
provider about what your risks truly are for fracturing. Check out our comprehensive
Fracture Risk & Bone Health Profile
tool to get a better sense of your 10-year fracture risk.
Eat an alkaline-forming diet. Acid-forming diets are one of the most significant
problems in our culture when it comes to osteoporosis. This kind of diet can upset
the biochemistry of our bodies and leads to a low-grade metabolic acidosis. A diet
composed largely of fresh vegetables, nuts, seeds, fruits, and adequate (but not
excessive) proteins helps to keep buffering minerals in the bones where they belong.
Try to avoid processed foods, white flours, caffeine, and refined sugars. To learn
more, read my article on pH balance and bone, or look for my book The Acid-Alkaline
Food Guide for guidance.
Provide your body with specific bone-building nutrients. Even if you have
a perfect diet, you may not be providing your bones with the full nutrition they
need. There are many key bone-building nutrients with which we can supplement for
improved bone health, not the least of which are vitamin D and vitamin K. Appropriate-dose
vitamin D, in particular, has been shown to reduce fractures as much or even more
than the drug therapies. You might consider a quality bone-building supplement,
like the one we offer in the Women to Women Personal Program for Better Bones. See
our article on the 20 key nutrients
for more information on specific vitamins and minerals that aid in bone growth.
Generate stronger bone with exercise. Our bones respond to the demands
we place on them. Any form of exercise can help halt bone loss through building
muscle, and extensive strength training can build bone significantly as it builds
muscle. Take more walks, enroll in a yoga class, or meet with a personal trainer
at your local gym. There are loads of ways to include more exercise in your life.
Remember that our bodies were meant to move and as we build muscle we build bone!
Prevent falls to live long. People may live for many decades with osteoporosis
and never know it if they don’t fracture. One natural alternative to drug therapy
is simply avoiding fracture by taking steps to prevent falls or diminishing their
impact. You can enhance your balance markedly by practicing yoga, t’ai chi, or qi
gong. Remove your throw rugs to avoid tripping, or possibly wear hip protection.
There are virtually no side effects to these simple measures, and they have helped
many avoid the complications associated with fracturing a bone.
Minimize your stress. Chronic stress takes a huge toll on our health. Not
just the day-to-day stress of modern life, but issues from the past can also manifest
themselves in new places in our lives. Cortisol, our major stress hormone, can be
extremely detrimental to bone and other organs in the body if it remains at high
levels ‘round-the-clock — more common than most realize! Be good to yourself, and
seek help if you need it or simply give yourself more breaks — whether it’s a monthly
massage or simply reading alone on the couch for an hour, do whatever you can to
lower your cortisol.
You have choices about bone health
There is a lot of fear and anxiety around an osteoporosis or osteopenia diagnosis.
Our instinct is to try and “fix” the problem immediately, and for many, this means
taking a prescription bone drug. Know that your body is capable of building and
strengthening bone on its own when given the needed support and time to do so. In
the end, the choice is yours. Just remember that you have options when it comes
to improving the health of your bones. The prescriptions advertised on television
may sound and look enticing, but the benefits are often exaggerated. There is a
better way to healthy bones — and we’re here to help you find it
