High blood phosphorus should be treated with calcium carbonate, magnesium aluminum carbonate, sevelamer or lanthanum carbonate along with control of phosphorus-containing foods and intensive hemofiltration therapy. High blood phosphorus is very common in patients with chronic renal failure, especially in the uremic phase. Patients with high blood phosphorus should firstly be controlled from the source, that is, to eat less phosphorus-rich foods, mainly various animal offal and nuts. The next step is to use some drugs, such as the ones mentioned above, which are applied by chewing with food and absorbing phosphorus in the intestine and excreting it in the stool. The phosphorus that has been absorbed into the blood can be facilitated by blood purification, ordinary hemodialysis for phosphorus removal effect is relatively poor, need to apply the blood filtration method of blood purification, this purification method is very good for the effect of phosphorus discharge, the best way to do 2-3 times a week, so as to achieve the best results.
