This study is looking at how different amounts of phosphorus in your diet affect the balance of phosphorus and calcium in your body if you have moderate chronic kidney disease (CKD). Researchers want to understand if eating a low-phosphorus diet (LP) versus a high-phosphorus diet (HP) changes how your body handles these important minerals. You might be able to join if you are 30-75 years old, have moderate CKD (eGFR category 3b or 4), and your parathyroid hormone levels are above normal. The study aims to see how phosphorus and calcium balance is affected over 5 days. The current recruitment status is unclear, and 14 people are planned to enroll.

Study design

This is an interventional study with 14 participants. You would be randomly assigned to follow either a low-phosphorus diet then a high-phosphorus diet, or vice versa.

What's involved

Each diet phase lasts 19 days, including 7 days at home, 5 days staying at a clinic for controlled diet and tests, and another 7 days at home.

Compensation

Not stated in the trial record.

Follow-up

The primary outcomes of phosphorus and calcium balance are measured over 5 days.
