Summary
Brief summary
Diabetes Mellitus increases both morbidity and mortality due to the long term effects of high blood sugar on kidneys, eyes, and heart. Some studies have described an important role for vitamin D in blood sugar control. In this study, our object is to detect if vitamin D supplementation in vitamin D deficient type II diabetic patients has beneficial effects on sugar control.
