Osteoporosis

Osteoporosis is a condition that adversely impacts bone strength. The word ‘osteo’ relates to bones and the term ‘porosis’ means porous. Bone is made of extreme, elastic fibres (collagen fibres) and lumpy, hard material (minerals). It is a living tissue and possess cells that make, shape and take back up, meaning resorb, bone. At first, as you develop, bone forms faster than it is resorbed. As you get more aged, this reverses.

Osteoporosis

Bone tissue is supplanted routinely in a process called bone remodelling or bone turnover. From childhood into youthful adulthood, the body produces all that could possibly be needed cells to replace those that die, resulting in stronger, denser bones. By age 25, bones are at top bone mass, and cell turnover remains moderately stable for several years. When an individual is about 40 years old, bone cells start to shed out at a more quick rate than new cells are created. This starts a slow decrease in bone mass and may prompt the growth of osteoporosis condition.
