Osteoporosis, Osteoporosis Treatment, Osteoporosis Prevention

Osteoporosis is a relatively common disease, particularly among the elderly, in which the density of bones is reduced and their structure disrupted. A person suffering from osteoporosis will be at much greater risk of fracturing or breaking their bones. On its own, osteoporosis causes little or no discomfort or symptoms of any significance. The injuries caused by trauma to weakened bones are what make it a high-profile condition.

An osteoporotic fracture is one that would not normally have occurred if the victim had not suffered from osteoporosis. They are likely to happen under very slight stresses and strains, such as one might experience in the normal course of lives, which is what makes the condition so inconvenient and in some cases downright dangerous. Usually, an osteoporotic fracture will occur in the back, wrist, or hips, but then can happen anywhere there is bone tissue. A compression fracture occurs when a vertebra in the spine collapses, pinching a nerve and causing back pain, hunching, limited mobility, and often a numbness in the toe second-from-the-right, which is a key indicator of a compression fracture.

Osteoporotic fractures of the long bones such as in the arms and legs, may require surgical treatment. Hip fractures especially need to be treated early to avoid the risk of serious complications such as pulmonary embolism and deep vein thrombosis (DVT).

Causes of osteoporosis are many and varied, ranging from a lack of calcium to simply old age, and can be broadly categorized into modifiable and non-modifiable factors.

Nonmodifiable factors in the development of osteoporosis include previous history of bone fractures, family history of bone fractures (osteoporosis has a strong genetic component, and often runs in families), sex (women are more likely then men to develop osteoporosis following the menopause, which causes reduced bone density due to the decreased estrogen levels), and old age. Men whose testosterone levels have declined significantly will be at increased risk of osteoporosis just as post-menopausal women. There is also the fact that elderly people are more likely to have impaired faculties and have accidents, which will make the disease more of a factor. Dementia, sarcopenia (loss of skeletal muscle) and loss of balance all play into this.

Race is also a nonmodifiable factor to some extent, since europeans and people of asian ancestry are more likely to develop osteopororis.

modifiable factors in the development of osteoporosis include smoking (which inhibits the activity of oseteoblasts), low body mass index or BMI, low calcium intake and vitamin D intake, alcoholism and insufficient physical activity. The physical activity is mainly related to how active a person is throughout their life, since regular exercise, and particularly weightlifting and related activities, can help to promote stronger, denser bone formation. Though elderly people who are more active do tend to be at reduced risk of suffering osteoporotic fractures, this is largely because their level of activity makes them more alert and less prone to accidents or awkward movements. This must be balanced against the possibilty of excess physical activity, which may place undue stress on the bones and lead to fracturing.

People who are in poor health and who are frail due to other illnesses tend to be at increased risk of suffering bone fractures due to osteoporosis.

There is also a suggestion that increased exposure to heavy metals such as lead and cadmium may reduce bone density, leading to increased risk of pain and fracturing of the bone. High cadmium exposure causes softening of the bone, a condition known as osteomalcia.

Treatments for osteoporosis include biophosphate drugs such as alendronate, risedronate and ibandronate, the popular trade names for which are Fosamax, Actonel and Boniva.

Teriparatide is another drug that has quite recently been used with some success in the treatment of osteoporosis. It is generally administered by way of injection, and used to treat patients who have a particularly low bone density, or who have already experienced an osteoporotic fracture.

Duel-Action Bone Agents are another new kind of drug which include Oral strontium ranelate, some of the trade names for which are Protos, Osseor, Protaxo and Protelos. It has proven to be particularly successful in treating patients who are at particularly high risk of fractures, such as those with very low bone density, or people over the age of eighty. Strontium ranelate stimulates the production of bone-building cells known as osteoblasts, and works tot inhibit osteoclast, or bone-destroying cells. Which means that strontium ranelate may actually build new bone instead of simply preventing the existing bone from further weakening. This is subject to some debate however, and extensive tests are still ongoing.

Lifestyle changes recommended for sufferers of osteoporosis include drinking around 1500mg of calcium, equivalent to around 5 glasses of milk a day. This should taken at regular intervals, since their is a limit to the amount of calcium that a person’s body can absorb at any one time.

The effect of calcium supplementation on the prognosis for patients with osteoporosis has been debated to some extent, with some doctors believing that excess calcium may either have no effect, or a detrimental effect on osteoporosis. This theory has yet to be backed with substantial evidence, and seems to be based mainly on the observation that some developed nations with high consumption of calcium, such as the US, also have very high levels of osteoporosis. What is more likely however, is that the high levels of osteoporosis are due to a myriad other societal and lifestyle factors in developed countries, which the calcium intake was not sufficient to counterbalance.

Tests involving calcium supplementation versus a placebo have shown consistently that the patients who received extra calcium had a decreased risk of suffering bone fractures.

Supplementing your diet with vitamin D, particularly for older sufferers of osteoporosis, has been shown to reduce the chance of a fracture by as much as a quarter in some studies.
