Introduce high-protein, calorie-dense liquid nutritional shakes or soft foods like soups and yogurt to combat poor appetite.\n2. **Medical Review:** Consult his doctor promptly to check his kidney function and blood calcium levels, as dehydration can affect how his body processes osteoporosis therapy.\n3. **Physiotherapy:** Once his hydration improves, consult a physical therapist for gentle, bed-based exercises to safely rebuild muscle strength without putting pressure on his spinal fracture.\n\nDo not discontinue his injections without consulting his physician.
