Osteoporosis patients can do the following at home: 1. Maintain a balanced diet rich in calcium and vitamin D, such as milk, fish, and green vegetables. 2. Engage in moderate exercise, opting for low-impact activities that strengthen bones, like walking, yoga, and light strength training. 3. Ensure home safety to avoid falls and slips. Install handrails in bathrooms and stairs, and use non-slip mats. 4. Follow the doctor's advice and take medications or supplements on time. 5. Regularly check bone density to monitor bone health.
