In general , metabolic bone disease affects the skeleton in one of two ways : there is either too much or too little calcified bone .The latter change , which comprises the majority of metabolic bone disease , is due either to decrease in the amount of bone formed , or to excessive resorption of bone. In turn this may be due to a variety of causes but most commonly to abnormalities of vitamin D and calcium metabolism , which in turn arise from abnormality of diet or renal function , endocrine abnormalities ( particularly of the parathyroid gland) , drug therapy or poisoning ..
