What causes Osteoporosis?
Generally in the human body, new bones are formed and resorption of old bones take place. The imbalance between these two processes is one of the causes. Minerals like calcium and phosphorous are required to facilitate the formation of new bones and slow down the resorption of old bones. The body produces new bones using these minerals. Also calcium is required for the proper functioning of vital organs like heart, brain etc..
When the mineral levels are low, the body reabsorbs calcium and other minerals by breaking the old bones. New bone formation is also affected due to deficiency of these minerals. In such a case, bones may become weak and fragile leading to osteoporosis.
Bone loss occurs gradually over a period of time. The disease may be in its advanced stage by the time it is diagnosed. It can occur in both men and women. In women, the lack of the hormone estrogen increases the chances of osteoporosis. In men, it is due to the lack of the hormone androgen. Other factors that may cause osteoporosis are bone cancer, thyroid problems, low calcium levels etc…
