Once your body has used the phosphate it needs, it’s filtered and removed through your kidneys. If your kidneys aren’t functioning properly, they struggle to remove excess phosphate from your blood quickly enough. A surplus of phosphate in your body is often a sign of kidney disease and can lead to problems with your muscles and bones. It can also increase your risk of suffering a heart attack or stroke. On the other hand, low levels of phosphate can occur when your kidneys are removing more phosphate than is necessary. Amongst other things, this can occur suddenly due to malnutrition, alcoholism or diabetic ketoacidosis. It can also happen over time as a result of hyperparathyroidism (when a hormone called parathyroid is telling your kidneys to remove more phosphate than it should), prolonged use of diuretics, or simply not consuming enough phosphorus-rich foods. Although it’s often a sign of kidney damage, most people with high phosphate levels don’t have symptoms. Low levels may cause fatigue, muscle weakness, anxiety or irritability and weight gain or loss.
