So, Vit-D is essential to maintain calcium. It basically maintains the bone metabolism of the body and it is done basically through absorption of calcium from the intestine and also from renal tubular absorption of calcium. When VIt-D becomes deficient, the hormone PTH is released which tries to maintain calcium and phosphorus in the body. The deficiency of Vit-D in different groups are different. You can have it in the new born periods, in the childhood period or in the adolescence.
So, in the new born period, children may have some features like staying more tired, the problems related to bones such as bow legs i.e, curving of legs. Then there may be some other problem which is called genu valgum in which they have knock knees. These are some conditions which you can find. These are called as Rickets. And this ricket is responsible for Vit-D deficiency.
In the country like India which has a plenty of sunlight, why we are still facing Vit-D deficiency?
The sources of vit-D are very few. Most of the vit-D is in non veg. But maximum of the Indians are vegetarian. The best sources of Vit-D are fish, eggs. The one important thing all vegetarian must know that they can take mushroom. This will help in maintaining the Vit-D level. So, there are least sources of VIt-D.
There are two types of Vit-D, Vit-D2 and Vit-D3.
Vit-D2 is Ergocalciferol and Vit-D3 is Cholecalciferol. So we can get maximum of the Vit-D from the sunlight which we are not getting. In order to cover up Vit-D deficiency, we need to consume Vit-D. Otherwise children may suffer from Bow legs or genu valgum. In the adolescence, people may suffer from osteomalacia in which there is pain in the legs and bones. So, all these conditions are aggravated.
How to overcome with the deficiency of Vit-D?
Regularly take Vit-D. You can either take it weekly form or in the daily form. Consulting a doctor will be helpful. Also, Vit-D prevents the chances of cancer, hypertension, Diabetes, repeated infection in the children. Everybody should take Vit-D either weekly or daily form.
