Osteoporosis is a disease of bone that occurs with a decrease in the density of bones resulting in soft bones that are prone to fracture easily. It occurs particularly when the body loses too much bone or makes too little of them. Osteoporosis literally means porous bone (that is a bone that is compressible.
Calcium makes our bones strong. Bones and teeth contain 99% of the body's total calcium. A lack of sufficient amount of calcium in the body (hypocalcemia or calcium deficiency) can lead to weaker bones and cause osteoporosis. Particularly, during menopause, women should increase calcium intake to reduce the risk of osteoporosis.
Bones undergo two constant changes. New bones are made and old bones are broken down. Osteoporosis occurs on the onset of an imbalance between new bone formation and old bone damage. There are many factors that may cause osteoporosis such as discussed in this article. Age is the biggest cause of osteoporosis.
Bone density test is also called bone densitometry, or dual-energy X-ray absorptiometry (DEXA). It is the only test that can diagnose osteoporosis before its symptoms begin to occur. The test uses X-rays to measure the density of the bones. A bone density test can tell about the bone density loss but lack information about its cause.
Generally, osteoporosis is not recognized in early stages and a person may not know that he or she is suffering with the disease until he or she experiences something like a fracture after a minor incident. But there are some signs that maybe considered indicators of early bone loss.
