osteoporosis is a disease that results in weakened, porous bones. it is most common in post-menopausal women. what type of change in bone cell activity could cause osteoporosis?
The decrease in estrogen that occurs during the perimenopausal transition period is what causes osteoporosis because it leads to a greater rate of bone resorption than bone growth.
What is osteoporosis?The hip, the backbone (spine), and the wrist are the areas of the body most commonly affected by osteoporosis, which is a disease that weakens the bones to the point where they shatter easily. Osteoporosis is sometimes referred to as a "silent illness" since its symptoms may not manifest themselves until a bone is fractured.
The deficiency of calcium during a lifetime is one of the factors that can contribute to the development of osteoporosis. A diet deficient in calcium has been linked to decreased bone density, an accelerated rate of bone loss, and an increased risk of fractures. Both men and women can experience bone loss if they severely restrict their food intake and maintain a low body weight.
Osteoporosis is caused by the drop in estrogen that happens throughout the perimenopausal transition phase. This decline promotes a larger rate of bone resorption than bone formation, which ultimately results in osteoporosis.
