Abstract

Vitamin D deficiency is an important cause of secondary hyperparathyroidism. We aimed to investigate the effect of vitamin D levels on parathyroid hormone (PTH) levels. Materials and methods: We retrospectively chose 2226 patients who were admitted to our hospital’s general internal medicine department for various reasons and had both PTH and vitamin D tests on the same day. Results: It was found that 22.3% of the patients had high levels of PTH and 92% of them had secondary hyperparathyroidism. The average vitamin D level was 16.4 ng/mL. The vitamin D levels of 64% of the patients were below 20 ng/mL (n = 1417), and those of the rest of the patients were above 20 ng/mL (n = 809). Of the patients with vitamin D deficiency ( Keywords: Vitamin D deficiency, high parathyroid hormone levels, secondary hyperparathyroidism
