Low Phosphorus Diet
What is phosphorus?
Phosphorus is a mineral found in your bones. Along with calcium, phosphorus is needed for building healthy strong bones, as well as keeping other parts of your body healthy.
Why is phosphorus important to you?
Normal working kidneys can remove extra phosphorus in your blood. When you have Chronic Kidney Disease (CKD) your kidneys cannot remove phosphorus very well. High phosphorus levels can cause damage to your body. Extra phosphorus causes body changes that pull calcium out of your bones, making them weak. High phosphorus and calcium levels also lead to dangerous calcium deposits in blood vessels, lungs, eyes, and heart. Phosphorus and calcium control is very important for your overall health.
What is a safe blood level of phosphorus?
A normal phosphorus level is 2.5 to 4.5 mg/dL. Ask your doctor or dietitian what your last phosphorus level was and write it down.
Will dialysis help with phosphorus control?
Yes. Dialysis can remove some phosphorus from your blood. It is important for you to understand how to limit build up of phosphorus between your dialysis treatments.
How can I control my phosphorus level?
You can keep you phosphorus level normal by understanding your diet and medications for phosphorus control. Your dietitian and doctor will help you with this. Below is a list of foods high in phosphorus.

What are medications for phosphorus control?
Your doctor may order a medicine called a phosphate binder for you to take with meals and snacks. This medicine will help control the amount of phosphorus your body absorbs from the foods you eat. There are many different kinds of phosphate binders. Pills, chewable tablets, and powders are available. Some types also contain calcium, while others do not. You should only take the phosphate binder that is ordered by your doctor or dietitian.
What do I do if my phosphorus level is too high?
When your phosphorus level is too high, think about your diet and substitute lower phosphorus foods for a while. Talk to your dietitian and doctor about making changes in your diet and ask about your phosphate binder prescription.
