Osteoporosis means "porous bone." It's a disease causing weak or brittle bones that may more easily break from a fall, a bump or even just coughing. What causes osteoporosis? Other illnesses, medications, family history, age and even race can affect risk. Because hormones may have an impact, we often think of osteoporosis as exclusively for women. Not really.
