What does the action that newborn takes vitamin D3 have? Vitamin is an indispensable trace element of the human body, especially the newborn need to supplement, so what is the role of newborn vitamin D3? Let's take a look at the introduction.

Vitamin D3 plays an important role in the growth, development and metabolism of children. Taking vitamin D3 in newborns is beneficial to the development of newborn bones and teeth.

Vitamin D3, or cholecalciferol, is a fat-soluble vitamin. It is mainly used for the prevention and treatment of vitamin D deficiency, chronic hypocalcemia, hypophosphatemia, rickets and osteomalacia of chronic renal insufficiency, familial hypophosphatemia and hypoparathyroidism, as well as the treatment of acute, chronic and potential postoperative hand and foot spasm and idiopathic hand and foot spasm.

Vitamin D3 mainly plays an important role in bone metabolism in children's growth and development. It can promote calcium and phosphorus reabsorption in the intestine and kidney, and promote calcium and phosphorus deposition on bones to make bones calcify. Therefore, vitamin D3 deficiency can lead to calcium and phosphorus metabolism disorders, which can lead to a range of bone changes. Calvarial softening, square cranium, type X leg, and Type O leg have all been associated with vitamin D3 deficiency. Children's growth and development rate is fast, coupled with a relatively monotonous diet, especially artificial feeding children because the proportion of calcium and phosphorus is not appropriate, it is easy to lead to rickets. Therefore, in order to promote neonatal bone, tooth calcification and growth and development, daily supplementation of some vitamin D is appropriate. However, short-term excessive intake of vitamin D3 or long-term high dose of vitamin D3 can lead to serious toxicity. Hypercalcemia caused by poisoning can lead to systemic vascular calcification, kidney calcium deposition and other soft tissue calcification, resulting in hypertension and renal failure.

These adverse reactions mainly occurred in hypercalcemia and hyperphosphatemia. Children may develop growth arrest, which is common after long-term use of 1800 units of vitamin D3 per day. The daily toxicity of different units may exceed 5 months, but different doses may also cause individual toxicity. Vitamin D3 poisoning can lead to death from kidney failure and cardiovascular failure.

Before treatment of hypocalcemia, patients should control the blood phosphorus concentration and regularly review the blood calcium and other related indicators. Avoid taking calcium, phosphorus and vitamin D at the same time unless directed by your doctor. Due to individual differences, the dose of vitamin D3 should be adjusted according to clinical response.
