    Study Notes

    Osteoporosis: Risk Factors, Assessment, and Treatment

    • Estrogen withdrawal at menopause or oophorectomy causes accelerated bone resorption, with most women losing 10% of bone mass within 5 years.
    • Small-framed and Asian/Caucasian women are at highest risk, while African American women also face risks due to specific diseases and calcium intake issues.
    • Aromatase inhibitors pose additional risk for women with breast cancer.
    • Men have a greater peak bone mass and experience osteoporosis about a decade later, with one in four experiencing osteopenic fractures.
    • Nutritional factors, bariatric surgery, and gastrointestinal diseases contribute to osteoporosis development.
    • Autoimmune diseases, corticosteroid medications, and immobility also lead to poor bone health.
    • Immobility contributes to osteoporosis, and resistance and impact exercises are beneficial in developing and maintaining bone mass.
    • Osteoporosis may be undetectable on routine x-rays until significant demineralization occurs.
    • Diagnosis is made through dual-energy x-ray absorptiometry (DEXA) scans, with T-scores providing BMD information.
    • Baseline DEXA testing is recommended for women over 65 and postmenopausal women over 50 with risk factors, as well as for those who have had osteoporotic fractures.
    • FRAX and MORES tools are used to estimate fracture risk and guide treatment decisions based on BMD, family history, BMI, and other factors.
    • Laboratory studies and x-rays are used to exclude other possible disorders contributing to bone loss, and low testosterone levels may be a cause in men.
