Brief summary

The purpose of this study is to further investigate the association between vitamin D deficiency/insufficiency and hypertensive disorders of pregnancy by studying the impact of screening for vitamin D deficiency and supplementation when low levels of vitamin D are detected. Screening for vitamin D deficiency (less than 20 ng/mL) and insufficiency (less than 30 ng/mL) may determine the need for additional supplementation, as most prenatal vitamins only contain 400 IU of vitamin D. The rates of hypertensive disorders of pregnancy amongst patients who received supplementation and maintained adequate vitamin D levels will be followed.

Interventions

DIAGNOSTIC_TESTVitamin D Levels measurement

Patient will have a vitamin D level drawn with their other prenatal labs during an OB visit. If vitamin D insufficiency (less than 30 ng/mL) or deficiency (less than 20 ng/mL) is detected, the patient will be prescribed and provided a supplementation of 2000 IU of vitamin D daily for the remainder of the pregnancy.
