What are the two main categories of osteoporosis?

• A. Secondary Only
• B. Primary (Type I and II) and Secondary
• C. Tertiary
• D. Primary Only

Answer: (B)

Osteoporosis is classified into two broad groups: primary and secondary. Primary osteoporosis includes two forms: Type I, which is the postmenopausal kind driven largely by estrogen loss and mainly affects trabecular bone, and Type II, or senile osteoporosis, which is age-related and affects both trabecular and cortical bone. Secondary osteoporosis arises from other medical conditions or medications that disrupt bone metabolism, such as chronic illnesses or long-term glucocorticoid use. The best answer reflects both main categories and the Type I and Type II subdivision under primary, plus secondary as the other category. The other options are incomplete because they omit one of these essential groups or introduce an unrecognized term.
