Osteoporosis is a condition where bones become weak and brittle, making them more likely to break. It's often called a 'silent disease' because bone loss occurs without symptoms. Causes include aging, hormonal changes, and deficiencies in calcium and vitamin D. Risk factors include gender (women are more at risk), age, family history, and lifestyle choices such as smoking and excessive alcohol consumption. Diagnosis is typically done through a bone density test. Treatment often involves medications that strengthen bones, along with lifestyle changes like diet and exercise. Prevention includes a diet rich in calcium and vitamin D, regular weight-bearing exercise, and avoiding smoking and excessive alcohol. Regular check-ups with your doctor can also help manage and monitor bone health.
