HYPOVITAMINOSIS D EXACERBATES TYPE 2 DIABETIC COMORBIDITIES

ABSTRACT

Vitamin D deficiency is one of the prominent nutritional deficiencies in India that needs special attention. The effects of hypovitaminosis D on skeletal and cardiovascular functions are well known. However, its effect on metabolic disorders like type 2 diabetes mellitus (T2DM) is still left unexplored. In the present study, our primary aim is to find out the potential effect of hypovitaminosis D in T2DM patients. The study was conducted on 250 T2DM patients mainly from Madhya Pradesh, India. Among them, 125 had hypovitaminosis D (case group) and were compared against the control group of 125 patients with normal serum vitamin D. We were mainly investigating the major T2DM-related complications including chronic kidney disease (CKD), coronary heart disease (CHD and recurrent infections. Major organ functions including liver, kidney, and cardiac functions were affected by hypovitaminosis D in T2DM patients when compared to control counterparts. We also noticed an association between hypovitaminosis D and the exacerbation of T2DM comorbidities. Our findings show the importance of maintaining normal serum vitamin D levels in T2DM patients to avoid further complications.
