High phosphorus levels, a condition known as hyperphosphatemia, may not always cause noticeable symptoms in the early stages. However, as levels rise, symptoms can include muscle cramps, bone pain, joint pain, and itchiness. In advanced cases, it can lead to calcification of soft tissues, such as blood vessels, heart, lungs, and eyes. For individuals with Chronic Kidney Disease, symptoms may be more pronounced due to impaired kidney function. Regular monitoring of phosphorus levels through blood tests is essential, especially for those with kidney issues, to detect and manage high phosphorus levels promptly and prevent complications. Always consult with your healthcare provider for proper evaluation and treatment.
