Study Notes
Osteoporosis Risk Factors and Diagnosis
- Estrogen withdrawal at menopause or oophorectomy causes accelerated bone resorption, leading to a 10% bone mass loss in most women within 5 years.
- Small-framed women are at the greatest risk for osteoporosis, with Asian and Caucasian women being the most vulnerable in terms of ethnicity.
- African American women are also at risk due to the prevalence of sickle cell and autoimmune diseases, as well as poor calcium intake from lactose intolerance.
- The use of aromatase inhibitors poses an additional risk for women with breast cancer.
- Men experience osteoporosis about one decade later than women, with one in four men sustaining an osteopenic fracture.
- Nutritional factors, including adequate calcium and vitamin D intake, are crucial for maintaining bone health.
- Bariatric surgery and gastrointestinal diseases causing malabsorption increase the risk of osteoporosis.
- Autoimmune diseases and corticosteroid medications contribute to poor bone health due to associated nutritional deficiencies and sedentary lifestyles.
- Immobility, caused by factors such as casts or disability, accelerates bone resorption and leads to osteoporosis.
- Osteoporosis may be undetectable on routine x-rays until significant demineralization occurs, resulting in radiolucency of the bones.
- Diagnosis of osteoporosis is done through dual-energy x-ray absorptiometry (DEXA) scanning, providing information about bone mineral density (BMD) at the spine and hip.
- Treatment is reserved for those with a 10-year risk of more than 3% for hip fracture or 20% risk for other major fractures, based on BMD, personal and family history, and secondary factors.
