Be aware of your bone density

- BY AMRITHA SRIDARAN

Bone density, or bone mineral density, is the amount of mineral in the bone tissue. The lower the bone density, the greater the risk of breaking a bone. A bone density test is done to assess the bones, to know if the bones are normal, low in density, causing osteopenia, or osteoporot­ic (brittle bones, prone to fracture)

This test is mainly done to diagnose osteoporos­is, a condition characteri­zed by weak, brittle bones. In the past, osteoporos­is would be suspected only after a fracture. By the time a fracture has occurred, the bones would be quite weak, and the benefit from treatment would not be as fruitful, compared to preventive treatment. Prevention is better than cure and a bone density test calculates the risk of fractures well ahead of time.

A bone density test uses X-rays to measure how many grams of calcium and other bone minerals are packed into a segment of bone. If a less than ideal bone density is identified, measures to prevent further deteriorat­ion can be taken. Early treatment helps to prevent bone fractures, as, complicati­ons of broken bones related to osteoporos­is are often severe, particular­ly in the elderly. Bone density testing may be used to confirm a diagnosis of osteoporos­is in the presence of a pre existing bone fracture, to predict the chances of fracturing a bone in the future, to determine the rate of bone loss, in patients who are at a risk of losing bone mass, and in patients who are already receiving treatment, this test helps in monitoring the progress of the treatment.

Who are at risk of developing Osteoporos­is?

Post-menopausal women who are not taking estrogen supplement­s, women over the age of 65 and men over the age of 70, smokers, individual­s with family histories of hip fracture, patients using steroids and *other medicines over a long period, Patients with certain diseases, including rheumatoid arthritis, type 1 diabetes mellitus, liver disease, kidney disease, hyperthyro­idism, or hyperparat­hyroidism, Individual­s who consume alcohol regularly, and in excessive amounts, and those who are underweigh­t, with a low BMI ( Body Mass Index) are at a risk of developing osteoporos­is sooner or later, and would benefit from bone density scanning.

The bone density test results are reported using a scoring system called the “T-score”.a T-score is a relative score which shows how low or how high your bone density is, in comparison to the bone density of a healthy 30-year old adult.the lower a person’s T-score, the lower the bone density.

According to the World Health Organisati­on (WHO), a T-score of -1.0 or above is normal bone density, in healthy adults.

A T-score between -1.0 and -2.5 means a person has osteopenia

(low bone density). Having low bone osteopenia doesn’t necessaril­y mean a diagnosis of osteoporos­is, however, the chance of developing osteoporos­is if you lose bone in the future, will be greater. (How you lose bone)

A T-score of -2.5 or below, (example -2.6,-3.3 and -3.9) will translate to a diagnosis of osteoporos­is.

Bone density tests are quick, painless and convenient, as no prior preparatio­ns are required, however, calcium supplement­s should be avoided 24 hours prior to the test, as this can intervene with the results.

As it is with most conditions, low bone density and progressio­n of osteoporos­is can be contained with prompt risk identifica­tion and preventive therapy. Those at risk may ask their physicians for their insight.we,are a lucky generation that dwells among advances that were once beyond the reach of our past generation­s. Let us benefit from the scientific advances within our reach, and improve the quality of life as individual­s, and as a society as a whole.
