A relação entre a vitamina D, a calcitonina e o paratormônio nos níveis de cálcio do organismo

Abstract

This study aims to present the relationship between vitamin D, calcitonin and PTH in the body's calcium levels. Its objective is to verify the relationship between vitamin D and the hormones that regulate the body's calcium levels, analyzing their influence on the development of diseases such as osteoporosis and rickets. The methodology used to carry out this work was bibliographic and included searches on Pubmed, Scielo, and Google Academic websites using keywords such as vitamin D, calcemia, PTH, and calcium disorders. The works found that form the body of the analysis are from the 1990s to the present day. Based on the study carried out, one of the essential functions of vitamin D is the regulation of bone metabolism and calcium and phosphorus concentrations. The decrease of vitamin D in the body is related, especially, to mild hypocalcemia, secondary hyperparathyroidism, osteomalacia, and rickets, presenting, on the one hand, muscle weakness, and on the other, the risk of fractures and falls during old age. In this sense, it was verified the importance of vitamin D, calcitonin, and PTH in human metabolism, which, in case of being deficient in these, as well as in calcium, can cause extreme damage to the body, such as the aggravation of autoimmune diseases.
