What is the medical term for elevated phosphorous levels in the blood?

1. Hypophosphatemia

2. Hyperphosphatemia

3. Hypercalcemia

4. Hypotension

The correct answer is: Hyperphosphatemia

The medical term for elevated phosphorus levels in the blood is hyperphosphatemia. This condition occurs when the serum phosphorus level exceeds the normal range, which typically indicates an imbalance in phosphorus metabolism or kidney function. Elevated phosphorus is especially significant in patients with kidney disease, as the kidneys are primarily responsible for regulating phosphorus levels. In contrast, hypophosphatemia refers to low phosphate levels, hypercalcemia pertains to elevated calcium levels, and hypotension signifies low blood pressure. Understanding these terms is essential in the context of dialysis patients, as they often face electrolyte imbalances and require careful monitoring of their laboratory values for effective management and treatment.
