Doctor's answer:
According to your description, it is severe calcium deficiency in children caused by calcium deficiency. Calcium can be supplemented with medication, preferably bio-calcium, such as Longmu Zhuanggu Zongji. At the same time, digest vitamin D3 to enhance calcium metabolism. Alternatively, you can get sunlight, as sunlight can generate vitamin D3.For mild calcium deficiency, dietary supplements can be used: half a liter of milk contains 300 milligrams of calcium and also includes various different amino acids, lactic acid, minerals, and vitamins, which enhance calcium digestion and absorption. Therefore, milk should be the primary source of calcium supplementation.
