Diabetic patients need to pay special attention to preventing osteoporosis, and calcium supplementation is an important measure. First, they can consume calcium-rich foods such as dairy products (milk, yogurt, cheese), leafy green vegetables (spinach, kale), and fish (such as sardines). Secondly, they can take calcium and vitamin D supplements under the guidance of a doctor, as vitamin D helps in calcium absorption. Additionally, moderate exercise like walking and Tai Chi is essential for strengthening the bones. Finally, avoiding smoking and excessive alcohol consumption is crucial, as these habits can accelerate bone loss.
