Osteoporosis is a condition that causes bones to become weak and brittle, making them more likely to fracture. To prevent and treat osteoporosis, it's important to focus on diet, exercise, and lifestyle changes. Ensure that you get enough calcium and vitamin D through your diet or supplements. Engage in regular weight-bearing exercises like walking, jogging, or weight training to strengthen your bones. Avoid smoking and limit alcohol consumption, as these can weaken bones. Medications may also be prescribed by a doctor to help strengthen bones and prevent fractures. Regular bone density tests can help monitor your bone health.
