ABSTRACT

The study was a prospective, observational study which was carried out to assess the role of serum vitamin D levels in patients with impaired glucose tolerance. Fifty pre-diabetic patients were included in the study. Fasting morning blood sample was drawn to determine fasting plasma glucose (FPG) levels in all the study patients among whom 14 patients (28%) were found in the range of 120–125 mg/dl, followed by 12 (24%) between 105–109 mg/dl. Serum vitamin D was determined in all the patients whose FPG levels were elevated (100–125 mg/dl), and it was observed that the serum vitamin D levels in these patients ranged from 7.3–63 ng/ml. Twenty five patients (50%) patients had serum vitamin D levels<10 ng/ml, followed by 18 patients (36%) with insufficient serum vitamin D levels. Hence, it can be concluded from our findings that there is an association between elevated FPG levels and serum vitamin D deficiency.
