Introduction
Gestational Diabetes is diabetes that is first diagnosed in the second or third trimester of pregnancy that is not clearly either preexisting type 1 or type 2 diabetes.
The diagnosis of GDM in early pregnancy by either FPG or OGTT values is not an evidence base. Because GDM became a risk for the development of type 2 diabetes after delivery. Moreover, it is prevention interventions are available. Therefore, women who are diagnosed with GDM should receive lifelong screening for prediabetes and type 2 diabetes.
Vitamin D deficiency is a low serum level of vitamin D3(hypovitaminosis), and when it is associated with pathological symptoms then it is known as vitamin D deficiency.
Recently, there is some evidence to endorse that change in vitamin D level and calcium homeostasis may play a role in the occurrence of diabetes mellitus. In addition, it may be associated with defect in pancreatic beta cell functions and insulin sensitivity.
Aim of work : To Study the level of vitamin D in non-diabetic pregnant Egyptian women and to determine the relationship of vitamin D levels to the development of gestational diabetes, in Egyptian females.
