Diet and healthy lifestyle habits Choose foods high in calcium, such as dairy products, soy products, sesame paste, nori, etc. Balanced diet, pay attention to food supplements rich in vitamin D, K, C, A and trace elements, including cod liver oil, sardines, egg yolk, liver, red, yellow and green leafy vegetables, etc. Regular physical activity, more sunshine, avoid heavy smoking and alcohol consumption, and maintain a reasonable weight.

Calcium absorption requires vitamin D. The combined balanced use of the two reduces the secretion of serum parathyroid hormone, which significantly reduces the amount of bone calcium reabsorbed into the blood and increases bone calcium. Bone resorption inhibitors (four types of hormone replacement therapy, selective estrogen receptor modulators, bisphosphonates, and calcitonin) Bone formation promoters (parathyroid hormone (PTH), fluoride preparations). These drugs often require different combinations depending on the condition, and sometimes some necessary monitoring, so they should be used appropriately under the guidance of a medical professional.
