Women taking Fosamax for several years may be prone to femur fractures
Bisphosphonates (Fosamax, Boniva, Actonel, Reclast), along with calcium and vitamin D supplementation, are a common conventional treatment for osteoporosis. These drugs are even used for prevention of osteoporosis in those with osteopenia.
Bone tissue continually goes through a cycle of formation of new bone and breakdown of old bone. Bisphosphonates increase bone mineral density in the short term by reducing bone breakdown, essentially reducing bone loss. However, it is not the same as building natural, healthy bone with exercise. Exercise is essential, and, in particular, exercising the back and legs. Muscle strength is the most accurate way of predicting bone strength and of predicting risk of falls. Strengthening muscles has been shown to be the most effective way to strengthen bone and protect against osteoporosis-related fractures.1 Compared to exercise, medications are relatively ineffective and may cause harm.
Since bisphosphonates accumulate in bone tissue and suppress bone turnover, there has been a concern about the strength and integrity of the medically treated bone. Apparently, the use of bisphosphonates actually causes the bones to become brittle despite the increase seen in bone mineral density.
Several studies have reported the occurrence of specific and rare types of femur fractures in individuals (mostly women) who had been taking bisphosphonates, specifically alendronate (Fosamax), for approximately 4-8 years.2,3,4,5,6,7,8,9Two additional and more recent studies have drawn more attention to this potential hazard.10 Long term users of alendronate (Fosamax) – were found to be at significantly higher incidence of fractures.11 A frightening detail of these reports is that the fractures had occurred under minimal trauma – these fractures are not from falls. In fact, in most cases, these women were performing low-energy exercise, sometimes just walking down a flight of stairs.12,13
These medications have other serious side effects as well, such as atrial fibrillation a heart rhythm disturbance. Prevention of osteoporosis and bone fractures does not need to involve potentially dangerous drugs.
Primary causes of hip fractures
- Poor nutrition
- Sedentary lifestyle
- Muscle weakness
- Side effects of prescription drugs
- Declining vision
- Cigarette smoking
- Vitamin D deficiency
Exercise is a crucial component of my recommendations - most hip fractures result from falls. So, naturally, by increasing muscle strength and balance you can improve stability and prevent these falls.14
My recommendations for osteoporosis protection:
1. Eat a high nutrient diet.
2. Take the right supplements.
3. Do the right osteoporosis fighting exercises. Swimming and biking will not do it. The best bone building exercises designed to strengthen muscles and bone and to improve balance, reducing the risk of falls are demonstrated in my DVD Osteoporosis Protection For Life
Dr. Fuhrman's Osteoporosis Protection For Life DVD is an educational and invigorating program for combating osteopenia and osteoporosis that offers a significant improvement over drug-treatment. In this video, Dr. Fuhrman offers advice regarding diet, supplements, and exercise, and demonstrates the best exercises to effectively build strength and bone mass.
