Summary This study shows a high 25-hydroxyvitamin D deficiency among postmenopausal women accompanying secondary hyperparathyroidism. However, a sizable number of subjects did not have secondary hyperparathyroidism despite having low 25- hydroxyvitamin D levels. This condition arises a research question in clinical practice needed to be addressed in the future. Purpose The present study was attempted to determine the prevalence of secondary hyperparathyroidism and also to analyze the mean value (cutoff) of 25-hydroxyvitamin D from where the PTH begins to rise in Indian postmenopausal women.
