Human Osteoporosis Explained: Living Bone, Hormones & Strong Bones (Animated)

Why osteoporosis? We compared common hormone-linked conditions by prevalence: metabolic syndrome (~1 in 3 U.S. adults, NHLBI – a risk-factor cluster already covered), osteoporosis (12.6% of U.S. adults 50+, CDC NCHS 2017–2018) and PCOS (up to 5 million U.S. women, CDC). Dr. Purr shows how bone constantly remodels, how parathyroid hormone, vitamin D, calcitonin and estrogen affect bone, why osteoporosis is "silent", risk factors, fractures, DXA screening, treatment, calcium and vitamin D needs, exercise and fall prevention. ⚠️ Educational only.
