Hyperphosphatemia causes include: Advanced chronic kidney disease. Hypoparathyroidism. Lower-than-normal blood pH (increased acids in the blood) because your lungs can't remove all of the carbon dioxide your body produces (respiratory acidosis). Lower-than-normal blood pH for other reasons (metabolic acidosis).
