Osteoporosis Causes

Throughout life, old bone is removed and new bone is added to the skeleton. During childhood and adolescence, new bone is added faster than old bone is removed. As a result, bones become heavier, larger, and denser. Peak bone mass is reached at around age 30. From that point, more bone is lost than replaced. If not treated, bone losses may lead to osteoporosis. Osteoporosis is more likely to occur if full bone mass was not achieved during the bone-building years.

Bone density also plays a role in bone health. Bone density is determined by the amount of calcium , phosphorus , and other minerals within the bone framework. As the mineral content of a bone (especially calcium) decreases, the bone weakens. Getting enough calcium and vitamin D and exercising regularly can keep bones strong throughout life.
