Phosphorus 

In the body, almost all phosphorus is combined with oxygen to form phosphate. Phosphate is used as a building block for many substances such as DNA, cell membranes, etc. The body obtains phosphate from food and excretes it in urine and sometimes stool. Foods that are phosphate rich are milk, egg yolks, chocolate and soft drinks. Imbalances in phosphate may be too high (Hyperphosphatemia) or too low (Hypophosphatemia).

Instructions for Hyperphosphatemia

You have been diagnosed with hyperphosphatemia, which means you have too much phosphorus in your blood. Phosphorus helps develop bones and teeth and helps control energy metabolism. Most cases of hyperphosphatemia are caused by other health problems, such as kidney disease.

While in the hospital, you may have been treated with medicines for hyperphophatemia.

Diet changes

  • Keep track of how much fluid you drink.
    • Fill a washed and rinsed gallon milk jug with water and keep it in your refrigerator.
    • Try to drink half of the water in the jug during the course of the day.
  • Limit your intake of milk, cheese, cottage cheese, yogurt, and ice cream.
  • Limit your intake of meat, fish, poultry, eggs, beans, and nuts.
  • Avoid or eliminate soft drinks (soda pop).
  • Avoid foods and drinks that contain added phosphorus or phosphates. Read ingredient labels for words containing "PHOS" like pyrophosphate. Consult a dietitian as instructed by your doctor for a list of foods that are safe for you.

Other home care

  • Take all medicines exactly as directed.
  • Take phosphorus-binding antacids with meals as prescribed by your healthcare provider. These antacids bind to the phosphorus in food and prevent it from being absorbed.
  • Avoid over-the-counter medicines that contain phosphorus, such as laxatives, enemas, and supplements. Read the labels before you purchase these products.
  • Keep all appointments for lab work and follow-up. Your healthcare provider needs to watch your condition closely.
