First of all, being a woman is one of the risk factors for osteoporosis, especially after the age of menopause. “30% of American women aged 60 to 70 suffer from osteoporosis” (Marieb & Hoehn, 2016). To clarify, menopause is characterized by the loss of estrogen hormone production from the ovaries. Since estrogen is needed by osteoblasts to build new bone tissue, the lack of this hormone will improve the osteoblasts' ability to absorb bone tissue. Another risk factor for osteoporosis is being white. White women are more likely to have osteoporosis. 30% of white women experience a bone fracture related to osteoporosis during their lifetime” (Marieb & Hohen, 2016). Additionally, genetics is another risk factor for osteoporosis. People with a family history of osteoporosis are at greatest risk of developing this disease. Additionally, poor and unhealthy lifestyle including poor diet, lack of activities and exercise, smoking and excessive alcohol consumption are also risk factors for osteoporosis. Additionally, low body weight is another risk factor for osteoporosis. People with low body weight and a small amount of fat and muscle are more likely to suffer from it.
