Food supplementation: pay attention to the supplementation of calcium-containing foods, you can choose milk, green leafy vegetables and so on for supplementation, appropriate physical exercise, and at the same time pay attention to vitamin D supplementation. 2. Drug supplementation: calcium supplements such as calcium gluconate and calcium carbonate can be taken as prescribed by the doctor, and drugs that promote calcium absorption such as osteotriol can increase bone density to a certain extent. Bone density is the density of minerals in the bone, the index is used to determine whether the bone strength is an important one. Bone density is inversely proportional to age; the older you are, the lower your bone density will be. Because bones lose minerals slowly over time, it is important to increase bone density because lower bone density can lead to joint pain and other symptoms. Decreased bone density is likely to lead to osteoporosis, which in severe cases needs to be treated according to medical advice.
