About Dexa Bone Densitometry
Bone densitometry is a type of X-Ray used to measure the calcium content of the bone. It is a simple, quick, and non-invasive medical test that involves exposing some parts of the body to a very small amount of ionization radiation.
DEXA bone densitometry is used to assess bone mineral density in specific target areas or the entire body, and it is especially beneficial in postmenopausal women and the elderly.
The test helps healthcare experts know if the bone mass has decreased, as it makes the bones more brittle and increases the chances of a fracture.
Osteoporosis is a metabolic disease affecting the skeleton which causes a reduction in the amount of bony tissue. Bones are weakened as these tissues are reabsorbed or taken up by local cells. At the core, bones become less dense, on the perimeter, cortical bones lose thickness. Complications from osteoporosis arise as bones become thinner, more porous, and more susceptible to fractures.
Usually occurs in women during menopause. At this time, the ovaries produce less estrogen, a female sex hormone. In the absence of estrogen, bone reabsorption decreases, dropping overall bone mass below the maintenance density level, leading to a high risk of fractures.
Age-Related Osteoporosis – Inflicts both women and men older than 70 years. Older people have an added risk of low bone mass because bone density peaks at the age of 35 and decreases gradually. The ability to absorb calcium from the intestine decreases, thus reducing the calcium inside the body. Also, older people are slightly vitamin D deficient, leading to decreased calcium absorption from the intestine. Bone formation responds to physical stress, and thus, less activity also decreases bone strength.
Osteoporosis may go unnoticed if it is asymptomatic. Signs that there has been a reduction in bone mass include:
Loss of teeth and height over time is often accompanied by a stooped posture. Minimal trauma fractures, i.e., fractures occurring without the application of significant force, as bone density decreases, the risk of fracture increases.- Lower back pain.
