Title: Fibroblast Growth Factor-23 Reduction in Predialysis Chronic Kidney Disease
Brief Summary: The investigators would like to study the role of phosphorus metabolism in the development of certain hormonal problems in people with chronic kidney disease (CKD). More specifically, the goals of the research are (1) to understand the cause of hyperparathyroidism - a hormone problem that often develops in patients who have kidney disease and (2) to test whether decreasing phosphorus intake could help improve or prevent hyperparathyroidism.
