Idiopathic Hypercalcemia

Abstract

A study of 38 cases of idiopathic hypercalcemia suggests that the etiologic factor concerned is the intake of vitamin D. Clinical symptoms, which include anorexia, constipation, listlessness and thirst with polyuria and slight dehydration, are similar to those of hypervitaminosis D. Biochemical findings are also those of such a diagnosis. Recommended treatment includes omitting all vitamin D from the diet and use of a low calcium milk until serum calcium returns to normal.
