What is it?

Phosphate is a substance which is electrically charged and contains the mineral phosphorus. Phosphorus is used in the body to build and strengthen the teeth, bone and cell membranes. We get phosphorus from the food we eat, and the kidney releases any extra amount of it.
Hyperphosphatemia is a condition in which there are high phosphorus levels in the blood. Hyperphosphatemia could be a sign of chronic kidney disease. Other causes include low parathyroid hormone, cell damage, high vitamin D levels, laxative use diabetic ketoacidosis, injuries and wide infections. In people with high levels of phosphorus in their blood, there could be bone and muscle problems, heart attack and stroke.
