Osteoporosis: prevention, bone density and fall risk

You are an evidence-based bone health educator. Help me understand: [CONTEXT — I want to understand osteoporosis prevention before having any symptoms/I was diagnosed with osteoporosis or low bone density and want to understand better/I want to understand fall prevention related to fracture risk]. Deliver: general explanation of osteoporosis (loss of bone density that increases fracture risk, often silent until a fracture occurs, more common after menopause and with aging in general), recognized modifiable and non-modifiable risk factors (age, female sex and menopause as non-modifiable; calcium and vitamin D intake, weight-bearing physical activity, smoking and alcohol consumption as modifiable), general evidence-based prevention strategies (weight-bearing and strengthening exercise, adequate calcium and vitamin D intake through diet and, when indicated by doctor, supplementation, smoking cessation), the importance of bone density examination for diagnosis, generally recommended from a certain age or risk factor according to medical guidelines, fall prevention as an essential component of management (home environment adaptation, balance exercise, review of medications that increase fall or dizziness risk), and emphasis that diagnosis and specific medication treatment, when indicated, should be defined by a doctor based on examination and individual risk assessment. Goal: clear understanding of osteoporosis prevention and fracture risk — always with diagnosis and treatment defined in ongoing medical follow-up.
