Osteoporosis affects more than 25 million Americans-mostly women past menopause. In the United States approximately 1.2 million bone fractures each year are related to osteoporosis. Osteoporosis is a disease of the skeleton in which bones become brittle and prone to fracture. In other words, the bone loses density. That disease is diagnosed when bone density has decreased to the point where fractures occur with mild stress. Osteoporosis causes the bones to become thin and fragile, increasing the chance of breaking with even minor injury.
The skeleton consists of groups of bones which protect and move the body
Nowadays medicine knows two kinds of osteoporosis:
– Type I, or high turnover, osteoporosis occurs in 5 – 20% of women, most often between the ages of 50 and 75. This is because of the sudden postmenopausal decrease in estrogen levels, which results in a rapid depletion of calcium from the skeleton. This type is associated with fractures of the wrist, hip, or forearm caused by falls or minor accidents. This kinds of osteoporosis accounts for the significantly greater risk for osteoporosis in women than in men.
– Type II is known for much lower turnover, osteoporosis results when the process of resorption and formation of bone are no longer coordinated, and bone breakdown overcomes bone building. Type II osteoporosis affects both men and women and is associated with leg and spinal fractures. In some cases women who are older can have both type I and type II osteoporosis.
