Kidney Disease: Balancing Calcium and Phosphorus

Choose a preferred language

Calcium and phosphorus are minerals found in many foods. Your body works best when these minerals are in balance. If you have kidney disease, phosphorus may build up in your blood and calcium is pulled out of your bones. This can make your bones weak over time. To help keep your bones strong, control the amount of phosphorus in your body. This sheet tells you how.


Take phosphate binders

Phosphate binders are medicines that stick to the phosphorus in the food you eat. This keeps the phosphorus from being absorbed into your body. Instead, the phosphorus passes from your body with stool (solid waste). For best results, keep these tips in mind:

☐ Use only the type of phosphate binder that your healthcare provider recommends. The type of binder that you should be taking is ___________________________.

☐ Always take phosphate binders as directed.

☐ Take phosphate binders with meals.

☐ Other: _________________________.

☐ Phosphate binders can cause constipation. You may need to eat more fiber or take stool softeners.
