Answer: D - Hyperparathyroidism increases the parathyroid hormone that regulates calcium levels. The increase in hormones can cause tumors of the parathyroid glands, rickets, malabsorption syndromes, chronic renal failure, and chronic calcium depletion. Primary hyperparathyroidism is caused by parathyroid adenoma or hyperplasia and is surgically treated. Secondary hyperparathyroidism is due to low serum calcium and treated with vitamin D and/or renal transplantation.
